12.1GENERAL

12.2AUDIO

In the VST3 plugin this page is disabled, because the host owns the audio device.

The status below OUTPUT PAIRS shows the callback buffer duration, the driver-reported output latency, and audio underruns when the driver reports them. Buffer duration is only one part of output latency. Standalone playback accounts for the driver-reported output delay when scheduling Link/PilotNet audio. Full AutoPilot also accounts for its internal instrument-alignment delay; Player has no such delay. On iOS, Player uses the audio buffer’s hardware presentation timestamp plus reported output latency when that timestamp is available. Device measurements and listening tests may still reveal residual offsets. Failed device, sample-rate, or buffer changes display an error.

AutoPilotPlayer saves its audio device, sample rate, buffer size, and output routing in AutoPilotPlayer.audio.settings inside the AutoPilot application support directory. Synced host libraries persist separately in Synced Libraries, with a SQLite metadata snapshot per host and media files named by checksum. Received library edits and other Player preferences remain temporary; syncing refreshes the host’s read-only snapshot. For the Raspberry Pi DAC Pro, use its Direct hardware device without any conversions output. The Pi test configuration uses 44100 Hz / 64 samples; increase to 128 samples if playback produces underruns. The direct hardware path bypasses the desktop sound-server volume; start with your amplifier turned down.

On Raspberry Pi hardware, Player starts fullscreen with controls scaled up to 150%. The mixer receives more width and the waveform uses the remaining space. F11 toggles fullscreen; Escape leaves fullscreen. Other desktop Player platforms retain their existing window and scaling behavior. On the Pi, Audio and PilotNet dialogs stay attached to the Player window and fit within the display. Hover tooltips are disabled in the Pi Player. Animation follows the display refresh rate; a 60 Hz panel cannot show more than 60 distinct frames per second.

The experimental iPhone Player runs fullscreen in landscape and fits its controls inside the screen's safe area. Join the same Wi-Fi network as the AutoPilot library host and allow Local Network access. PilotNet/Link discovery requires a build signed with Apple's multicast networking entitlement. For private testing, a developer can launch Player with a direct library host address and key: ordinary TCP library browsing and track transfers need only Local Network permission, without TestFlight or multicast approval. Link sync still requires its network discovery. Development installation also requires Developer Mode on the phone. Desktop VST instruments and the desktop Elastique SDK are unavailable in this initial iOS build.

Player’s top bar shows the master beat alongside CLICK and its volume knob. CLICK toggles the metronome on the configured Cue output; the knob adjusts its level. These controls remain available in the Browser.

Player starts with PilotNet enabled each session. Beneath its volume/filter section, the clock panel shows the master/follower role, LINK peer count, Link bar phase and playback correction (RAMP). LINK 0 means no other Link peers are connected. MASTER, SYNC and W use the existing header ownership, player tempo-sync and wallclock controls. The BPM spinner and minus/plus controls are editable when the local header owns tempo; Command-hold minus/plus bends it. OUTPUT BPM is the main header's effective master tempo including bend; the separate PLAYER BPM readout shows the loaded player's current tempo. Tempo SYNC preserves an existing track phase offset; use the deck's phase-reset control to clear that offset when aligning beats. PHASE beneath Player BPM shows the current offset from the nearest beat in playback milliseconds, to two decimal places: positive is LATE, negative is EARLY. This readout reports the track’s phase adjustment, not a measurement of network or hardware latency.

12.3DECKS

12.4MIXER

PROCESS EQ/FILTER FOR DIRECT OUT defaults to on. Direct hardware output channels include the mixer EQ and filter when on; turning it off bypasses that channel tone stage, including its pre-fader Cue tap. Trim, volume, mute/solo, and effects still apply. Master-routed channels and VST3 host outputs always retain mixer EQ/filter processing. Arrangement lane EQ/filter remains part of the source mix. Changes crossfade over 5 ms.

FILTER / EQ in Mixer settings applies across the mixer, Perform Loop, arrangement editor/player and offline rendering:

• LP/HP RES: bipolar cutoff plus resonance, as before.
• ONE KNOB: FILTER sweeps the cutoff and WIDTH adjusts the gap between the LP and HP cutoffs. Width defaults to 1 when starting or switching into ONE KNOB mode; 1 restores the original full-width response and 0 is narrowest. Resonance starts at 0.3 and increases toward 0.85 near the center of the sweep as Width narrows. Double-click WIDTH to restore full width. Width uses the second filter control (the same saved parameter slot used for resonance in LP/HP RES mode). Leaving ONE KNOB resets that shared control to 0 for resonance; explicitly saved values are restored when loading a project.
• LP/HP: independent LP and HP knobs, with zero resonance. Both knobs are neutral fully left; turn clockwise to increase filtering. Double-click restores each neutral position. Their values are saved separately. Switching into LP/HP mode resets both knobs to bypass.
• LOW / MID (Hz) defaults to 250 Hz and MID / HI (Hz) to 2500 Hz. LOW covers below the first crossover, MID the range between them, and HI above the second. The upper crossover must be higher than the lower. Frequency changes are smoothed during playback.

The updated Cytomic cutoff ranges are 100 Hz–16 kHz for LP and 50 Hz–8 kHz for HP (scaled down at sample rates below 44.1 kHz). Filter labels light up when their controls are away from neutral. Click a lit label to reset its control; in the arrangement editor this also disables automation for that control so the reset holds.

The DEFAULTS button below the EQ split fields restores 250 Hz and 2500 Hz; save when you close Settings to apply. Filter changes use Cytomic’s coefficient interpolation across each audio processing block. Separate LP/HP controls support MIDI mapping and OSC Filter/LowPass / Filter/HighPass, normalized 0–1.

FADER CURVE: LINEAR (dB), CONSTANT POWER, DIPPED, FAST CUT. EQ visibility is controlled here too.

12.5MIDI

• INPUTS: turn on the controllers you want to map (section 13). Only enabled inputs can be learned or used.
• OUTPUTS: enable the devices that clips and attached MIDI can play to. Mappings never send to them.
• DEVICES: REFRESH rescans, and the line beside it shows how many inputs and outputs were found.
• DECK ROUTING: the default MIDI OUT device and CH for each of Decks 1–4.

12.6OSC

OSC INPUT ENABLED, the LISTEN PORT (default 9090), STATUS, and the five SENDERS for the OSC lanes in tracks, clips and arrangements. See section 14.1.

12.7OSC FEEDBACK

The DEST IP and PORT for state feedback (default 9096), RESEND STATE, and the SUBSCRIPTIONS that choose which header, deck and mixer values are sent. See section 14.10.

12.8DATABASE

• LIBRARY → DATABASE FILE: reveals the database.
• IMPORT → REKORDBOX: XML import (section 2.4).
• RESET → CLEAR DATABASE / FULL RESET: maintenance (section 3.6).
• Library checks and repairs have moved to the Library Manager.

12.9VST

• ENABLE VST / VSTi SUPPORT is the global switch at the top, on by default. It applies and saves immediately, briefly restarting audio. Turning it off saves patches, unloads all hosted instruments and their helper processes, prevents plugin loading and scanning, and bypasses all VST-related audio and MIDI alignment delays, including the fixed instrument buffer used when no instrument is loaded. Turning it back on restores the suspended instruments from their saved patches. If a patch cannot be saved, the switch stays on and reports the error. While support is off, only the switch is shown; the scanner and plugin information return when support is enabled.
• Device output-latency compensation, Link timing correction, user MIDI timing offsets, and native mixer EQ/effects remain active. Cancel a running scan before switching support off.
• VST3 LOCATIONS shows the folders that are scanned: folders listed in the VST3_PATH environment variable, your user VST3 folder (~/Library/Audio/Plug-Ins/VST3 on macOS, %LOCALAPPDATA%\Programs\Common\VST3 on Windows), the system VST3 folder, and any folders you add. FOLDERS lists them and has Add Folder…; click one of your own folders in that menu to remove it.
• SCAN VST3 scans new and changed plugin files, up to four at a time, each in a separate helper process. Unchanged files reuse their saved results, so rescans are quick. CANCEL SCAN stops at once and keeps the previous results.
• A plugin that takes longer than 10 seconds is often waiting for a licence or activation window. Finish that window, or press SKIP to move on. A plugin is skipped automatically after 90 seconds.
• ISSUES lists plugins that could not be scanned with the reason (crashed, timed out, skipped, wrong processor type, no plugins found). Click one to retry it, or choose Retry All Skipped, Rescan Everything or Show Scan Log. Skipped plugins are not retried on later scans until the file changes or you retry them.
• Right-click a plugin in either list to choose Use as Instrument, Use as Effect or Automatic, for plugins that describe themselves incorrectly.
• The INSTRUMENTS and FX lists have checkmarks. Unchecked plugins are hidden from choices and new instances, while existing playback carries on. Checkmarks persist across rescans.

13.1Before you start

1. Connect the controller and open Settings → MIDI (section 12.5). Under INPUTS, turn the controller on. Use REFRESH if it isn't listed. The change applies when you close Settings and choose to save.
2. Only enabled inputs can be learned or used. AutoPilot rereads the list about once a second, so a controller you enable while the Mapping page is open turns from red to green without a restart.
3. Mappings never send anything back to the controller. There is no LED or motor-fader feedback over MIDI. If a surface needs to show AutoPilot's state, use OSC feedback (section 14.10).

13.2Quick learn (MAP)

Quick learn assigns a control without leaving Perform.

1. Press the learn key at the right end of the header (the MIDI plug icon). It turns blue. It's available in Perform, Perform Loop and Arrange; in Arrange, only header, Browser and insert-window controls can be learned.
2. Every mappable control gets a blue tint and a pointing-hand cursor. Mapped inputs don't fire while learn is on.
3. Click a control. A dialog titled MIDI / KEYBOARD LEARN – waits for input.
4. Move a knob or fader, press a pad or note, or press a key. The dialog closes as soon as AutoPilot hears it.
5. Click the next control, or press the learn key again to finish.

Quick learn adds an input. It never removes the control's existing inputs, and it lets an input you already use drive this control too. The only thing it refuses is the exact pairing that already exists ("That input already controls …"). Press Escape or CANCEL to stop without learning.

A few controls can only be learned this way, such as a mixer channel's FX key and the BYPASS ALL key in the insert window.

Outside learn mode, a mapped key on screen is drawn pressed while its input is held (or flashes briefly for a single press), so you can see what your controller is doing.

13.3The Mapping page

Choose MAPPING from the Mode menu to manage every assignment. The header stays at the top, and the page fills the rest of the window. While it's open AutoPilot only listens: inputs are shown and logged, but no control fires.

The page has three columns.

PROFILE and APPLICATION CONTROLS (left)

ASSIGNMENTS (middle)

Every assignment in every area, in the order you made them. Each row shows the control, then the input: device, channel and message (for example CH 1 · NOTE 11), KEYBOARD Q, or NOT LEARNED.

An amber ×N badge means this input drives N controls. CLEAR ALL MAPPINGS removes every assignment straight away, without asking, so save your profile first.

LEARN & CONFIGURE (right)

13.4Making a mapping

1. Choose an AREA and, if it has one, the deck, channel or lane.
2. Select the control in the list. Use FILTER or SEARCH to find it.
3. Press ADD ASSIGNMENT, then LEARN.
4. Move the hardware control or press the key.
5. Adjust INVERT, MINIMUM / MAXIMUM or TOGGLE ON EACH PRESS if you need to, and check the RESPONSE chart.
6. Save the profile.
7. Switch back to Perform or Edit to play with it.

To move to a different controller, select each assignment and press LEARN on the new device. A mapping belongs to one device and one MIDI channel.

13.5Control types

Every control has a fixed type, which decides how inputs drive it. The type isn't something you choose; the options in BEHAVIOUR adapt to it.

For every type except Value and Selection, any MIDI value above 0 counts as pressed and 0 as released, whether it comes from a note, a CC or the pitch wheel.

Step and Bend are what you need for jog-style or encoder buttons. For example, map the controller's "beat back" pad to BEAT SKIP with INVERT on, and its "beat forward" pad to the same control without it. The control then shows 2 INPUTS.

13.6Areas and controls

FILTER1 and FILTER2 follow whatever the channel's filter is set to (section 7.1), so a mapping keeps working when you change filter type. The sampler's controls include every lane (SAMPLER LANE 1–8 / …) as well as the selected lane.

13.7Profiles

Your assignments are saved automatically with the app and come back at the next launch, together with the profile name and whether it has unsaved changes. To keep a set for a particular controller or gig, save it as an .apmidimap profile.

A profile can hold up to 512 assignments and 1 MB. If a file can't be read, you see an error and the assignments you had stay loaded.

Profiles from older versions still open:

• OSC assignments are skipped, because OSC now uses the fixed API.
• Assignments made with the former DDJ-FLX4 preset load as ordinary MIDI assignments.
• Retired mixer filter targets (cutoff, resonance, low pass and high pass as separate controls) are skipped. Map FILTER1 and FILTER2 instead.

13.8Keyboard mappings

• Learn a key the same way as a MIDI control. Shift, Control, Option and Command combinations count as separate keys, so Q and Shift+Q can do different things.
• Mapped keys work in Perform and Perform Loop, while the main window is in front.
• They don't fire while you're typing in a text field, while a dialog is open, or while quick learn is on.
• A mapped key takes priority over the app's own shortcut for that key in Perform.
• Autorepeat is ignored. If the window loses focus while you hold a key, the control is released, and you need to press the key again.
• Escape can't be mapped. It always cancels learning.

13.9What's supported

If MIDI arrives faster than AutoPilot can handle it, every held control is released and the status line reports that messages were dropped. Your mappings stay on.

14.1Setting up

Open Settings → OSC.

Changes apply when you close Settings and choose to save them. Send your messages over UDP to the listen port on the AutoPilot computer's IP address. Where to send state back is set separately, in Settings → OSC FEEDBACK (section 14.10).

14.2The OSC API window

The OSC API window lists every address AutoPilot accepts, explains each one, and shows the messages arriving, which makes it the quickest way to set up and test a surface. Open it from the Mapping page: Mode → MAPPING, then OSC API in the PROFILE column.

14.3Message rules

• Addresses start with the address root, /AutoPilot/ by default.
• Matching ignores case, so /autopilot/deck/1/playpause works. Wildcards (*, ?, […]) aren't supported; send each address in full. Addresses must be shorter than 128 bytes.
• Most messages carry one argument, an int32 or a float32. A message with no argument, a single string, or a non-finite number is ignored, and so is a message with extra arguments for a one-argument address.
• Three addresses take several arguments: Deck/{n}/HotCue, Deck/{n}/SetCueLoop and Deck/{n}/Sampler/LaneSet.
• Bundles are accepted. Their messages are applied in order as soon as the bundle arrives; time tags are ignored.
• A route does nothing if its control isn't available. For example, a track-deck route is ignored while that deck holds a sampler, and Header/BPM is ignored while the header doesn't own the clock.

The kind of each address is shown in the OSC API window and in the tables below.

Examples:

/AutoPilot/Header/BPM              float 126.0
/AutoPilot/Header/Quantize         int 4            (1/4)
/AutoPilot/Deck/1/PlayPause        int 1
/AutoPilot/Deck/2/BeatSkip         int -8           (back 8 beats)
/AutoPilot/Deck/1/HotCue           int 3, int 1 … int 3, int 0   (hold cue 3)
/AutoPilot/Deck/1/PhaseBend        int 1 … int 0
/AutoPilot/Mixer/CH3/Volume        float 0.75

14.4Header

Addresses: /AutoPilot/Header/…

14.5Browser

Addresses: /AutoPilot/Browser/…

Longer aliases also work: Navigation/Up … Navigation/Back, LoadDeck1 … LoadDeck4, and Load/Deck1 … Load/Deck4.

14.6Track and arrangement decks

Addresses: /AutoPilot/Deck/{1-4}/…

Transport and clock

Loops and skipping

Pitch, phase and waveform

14.7MIDI clip decks

Addresses: /AutoPilot/Deck/{1-4}/Clip/…

14.8Sampler decks

Addresses: /AutoPilot/Deck/{1-4}/Sampler/…

14.9Mixer and Arrange editor

Mixer — /AutoPilot/Mixer/CH{1-4}/…

MIDI mappings and OSC feedback use the same Filter1/Filter2 pair across filter types, including Loop Perform. Subscribe to the enabled flags to update controller availability when the filter type changes. The former parameter-specific filter mapping targets and OSC addresses are no longer supported; use Filter1 and Filter2.

The former native FX routes (/AutoPilot/Mixer/CH{n}/Reverb/… and so on) are still accepted but do nothing; use FX and FX/Macro/{1-8} for VST3 inserts.

Arrange editor — /AutoPilot/Arrangement/…

These control the arrangement open in Arrange mode, not an arrangement deck.

14.10Feedback: what AutoPilot sends back

AutoPilot can send its state to a control surface, lighting desk or visuals app, so faders, buttons and displays stay in step with what's happening.

1. Open Settings → OSC FEEDBACK and enter the DEST IP (an IPv4 address) and PORT (default 9096).
2. Under SUBSCRIPTIONS, tick the values you want. Each item covers all four decks or mixer channels; a folder shows how many items inside it are ticked. TOGGLE ALL / TOGGLE NONE select everything or nothing, and CLEAR is the same as TOGGLE NONE.
3. Ticking and unticking takes effect immediately. The destination applies when you close Settings and save.

There's no update rate to set. A value is sent as soon as it changes, and only when it changes. Time is the exception: it's sent at most once a second. Beat messages (Header/Clock and both Transport messages) are sent on every beat, in order, and cue events are sent the moment they happen, so you can drive lighting or visuals from them.

Press RESEND STATE, or send /AutoPilot/Feedback/Resend with any non-zero value, to receive every subscribed value again, which is useful when a surface reconnects. Changing the settings or the address root also resends everything. A value that doesn't apply (for example a sampler value while the deck holds a track, or anything for an empty deck) isn't sent, and is sent again once it applies.

Feedback addresses use the current address root. {n} is deck or channel 1–4.

Header and palette

Every deck (Deck/{n}/…)

Cues (Deck/{n}/…)

Track decks (Deck/{n}/…)

MIDI clip, arrangement and sampler decks

Mixer (Mixer/CH{n}/…)

Integers are sent as i, decimals as f and text as s. Messages with several values are sent as one message with several arguments.

14.11Outgoing OSC from tracks, clips and arrangements

OSC lanes you author in Edit (section 8.5) and Arrange (section 10) are sent to the five SENDERS in Settings → OSC, separately from feedback. Each lane chooses which senders it goes to. Envelope lanes send a float (or an integer, if the lane is set to send integers) scaled between the lane's minimum and maximum, and only when the value changes; message lanes send their text. These messages go out in Perform, and while you play in the Edit and Arrange editors.

15.1Keyboard shortcuts

15.2Mouse modifiers

On Windows and Linux, Command gestures use Ctrl.

Reporting a problem

Include:

• your OS and version
• the AutoPilot version (shown in the About window, opened from the AUTO/PILOT wordmark)
• the exact error text
• the steps that reproduce it
• a Library Manager report (EXPORT REPORT), if the problem involves the library

Join the AutoPilot Discord

The AutoPilot Discord is worth joining. Ask questions, share what you're building, compare setups and connect with other AutoPilot users. It's also a good place to check whether someone else has already run into the same problem, and to post a report.

Version 0.1.904

OCT 17, 2026 · MACOS · WINDOWS · BETA

• Open Settings inside the main window over a dimmed backdrop, scaled up to 15% larger for readability. Keep SAVE AND CLOSE and CANCEL, prompt to save from the corner close key or Escape, and move the fader-curve preview below its choice.
• Confirm before ejecting or replacing a playing deck, leaving Perform while a deck plays, or leaving Arrange with unsaved changes. Offer SAVE AND EXIT for arrangements; General > SUPPRESS WARNING DIALOGS skips these confirmations.
• Open track import options and progress inside the main window over a dimmed backdrop.
• Add a Mixer OUTPUT ROUTING diagram with separate TRIM, EQ, FILTER and VOLUME controls for hardware outputs. Bypassed trim and volume use unity gain; bypassed EQ and filter use neutral controls. Dim bypassed channel controls and ignore their gestures and mappings, preserve the previous EQ/filter preference, and keep full processing for Master and VST3 host outputs.
• Automatically fit the arrangement render range from timeline start to the last clip when the clip extent or clip/track count changes. Preserve saved ranges on load and manual edits until those content changes, with undo/redo restoring the range.

Version 0.1.903

OCT 17, 2026 · MACOS · WINDOWS · BETA

• Rebrand the app as Syndicate with Untitled Audio Syndicate marks, a new app icon, and updated window titles, menus, dialogs, splash and About screen. Preserve existing bundle IDs, binary names and data folders.
• Move Loop Perform to View > Loop Perform while retaining its header mapping, and add View > Clock Status to show or hide the sync panel.
• Replace the header tempo buttons with a draggable readout: 0.01 BPM per pixel, or 0.1 with Shift; double-click to enter 20–999 BPM. Header tempo controls adjust the master deck's tempo fader when a deck owns the clock outside wallclock mode.
• Refresh the header layout with master and wallclock keys, tempo, global quantize and activity LEDs; place the metronome controls in the sync panel and give the Q key an active highlight.
• Show HISTORY sessions beside the track list with date, time, track count and a live-session indicator; number tracks in play order. Fix session track logging and apply TRACK HISTORY changes when Settings are saved.
• Add SAVE AND CLOSE and CANCEL buttons to Settings while retaining the save prompt when closing the window.
• Make /Syndicate/ the default OSC root for control and feedback, retain /AutoPilot/ compatibility while using the default root, and migrate a stored /AutoPilot/ root to the new default.
• Replace arrangement-deck /2 and X2 keys with ROUTING for arrangements with multiple tracks. Show LED track-trim dials and 2 × 2 mixer routing keys in the control frame, give tracks the full display width, and style marker keys with round colour LEDs. Existing half/double-speed mappings remain available.
• Prefetch arrangement beat-skip targets before jumping and keep playback time advancing on a late stream page to prevent sync drift.

Version 0.1.902

OCT 16, 2026 · MACOS · WINDOWS · BETA

• Add General > HIGHLIGHT COLOR: keep the skin accent or choose a cue-palette colour for buttons, text, playheads, loop regions, knobs and VST learn states.
• Refresh browser controls with a folder-plus icon, highlighted source/action keys, consistent search fields and CLEAR keys, and import dialogs centred on the app.
• Add Audio > ENABLE CUE OUTPUT, off by default. When disabled, hide Cue routing, knobs and meter, silence the cue bus, and send the metronome and Perform browser previews to Master.
• Ask whether to save, discard or cancel when closing changed settings; audio routing changes still apply immediately.
• Improve clip-editor navigation with a play-start marker, playhead-following pan, pointer-centred zoom and draggable cue handles; expose the instrument’s eight assigned VST macros in the metadata area.
• Refresh an arrangement lane’s instrument and patch when dropping a MIDI clip whose saved instrument changed.
• Add quantized hot-cue region loops with Command-Shift-click and OSC SetCueLoop, plus an optional overview-click setting to launch the cue region you click.
• Simplify Perform Loop lanes by removing slip-loop and dotted/triplet keys while retaining mapped controls; REV now shows reversing and return playheads without lighting LOOP or filling the clip as a loop.
• Add OSC CuePass events aligned to the heard position, BarRamp feedback, and total bars/beats in TrackInfo. Combine Bar/Beat counters into Transport messages; remove Grid, Title and Duration messages, and make Time a position-only message sent at most once a second.
• Send changed subscribed OSC values on each timer pass instead of using a MAX-rate setting; refine Progress/Position precision and report live deck BPM to 0.01 BPM. Deck OSC OUT lights now represent item automation only, with feedback activity shown in the header.

Version 0.1.901

OCT 15, 2026 · MACOS · WINDOWS · BETA

• Expand MIDI and keyboard mapping coverage, allow multiple inputs per control and shared inputs across controls, and add percentage ranges, response charts, shared-input badges and a recent-input display.
• Make MIDI and keyboard mappings always active; input overflow releases held controls without disabling mappings. OSC uses the fixed API instead of profile assignments; older profiles load without their OSC assignments.
• Add a searchable OSC API window with copyable addresses, argument examples, incoming-message diagnostics and a configurable address root shared by control and feedback.
• Add multi-argument hot-cue and sampler-lane commands, grouped track/time/loop/grid feedback, hot-cue press and launch feedback, cue names and palette indexes, and cue-colour palette feedback for controllers.
• Remove per-step sampler sequencer OSC/mapping controls, the DDJ-FLX4 preset and dedicated controller feedback/jog integration, and the Resync command. Existing FLX4 profiles retain ordinary MIDI assignments; SYNC phase correction and RESYNC RATE remain available.
• Match arrangement-player clip drawing to the Arrange editor, including cue-coloured waveforms, labels, fades, loops and MIDI regions, and display each clip’s own lane audio.
• Fix drawing artifacts around mixer channel strips at scaled UI sizes.

Version 0.1.900

OCT 14, 2026 · MACOS · WINDOWS · BETA

• Reduce CPU use with selective UI repainting, cached theme colours, panel surfaces and track overviews, and lighter meter updates.
• Speed up library browsing, cue and beatgrid saves, track analysis and imports with cached sidecar reads, prepared database queries and targeted track refreshes.
• Optimise sampler voice processing, arrangement rendering, mixer filters and gain ramps, and VST instrument timing and delay buffers.
• Fix dim and flickering track overview waveforms while preserving played-section dimming.
• Improve audio safety with stronger track-swap protection and denormal handling throughout the standalone audio callback.
• Add CLEAR ALL to the mixer insert window to remove a channel’s inserts and associated macro assignments, bypass state and preset name after confirmation.
• Add a startup splash with activation and database-integrity checks; activated users go directly to the workspace without a flashing sign-in screen, and database problems offer a shortcut to the Library manager.
• Expand automated regression coverage and streamline shared UI helpers, engine code and application builds.

Version 0.1.852

OCT 14, 2026 · MACOS · WINDOWS · BETA

Add mixer FX presets and saved-state chains, playlist colours, overlaid arrangement automation with beat/bar nudging and curve editing, compact arrangement player controls, and OSC/MIDI timing alignment.

Version 0.1.851

OCT 13, 2026 · MACOS · WINDOWS · BETA

• Add VST3 insert effects to the four Perform mixer channels: up to four per channel in a pop-up chain window opened from FX, with drag reordering, PRE (after EQ, before cue and fader) or POST (after the fader) per slot, ON/bypass, editor show/hide, replace/remove and BYPASS ALL.
• Add eight macros per channel that can control parameters in any of the channel's inserts, assigned from the chain window or with MAP in each effect editor; map them and FX on/off to MIDI and OSC (/AutoPilot/Mixer/CH{n}/FX, /FX/Macro/{1-8}).
• Save insert chains, settings and macros automatically, keep missing effects with their settings, and compensate reported effect latency across channels within the instrument alignment budget.
• Stop processing the retired native FX rack; the FX key now opens the VST3 insert window.
• Quick-learn MIDI/OSC mappings for an open insert window's BYPASS ALL key and macro dials.
• Map the header PERFORM / Loop Perform switch to MIDI, keyboard and OSC (/AutoPilot/Header/LoopPerform, 0/1).
• Scan each VST3 plugin in its own helper process again, up to four at a time, so plugins that crash or hang during scanning no longer take AutoPilot down. Skipped plugins are remembered with the reason and retried on request or when the file changes; unchanged files reuse saved results; CANCEL SCAN stops immediately.
• Scan VST3_PATH and the per-user VST3 folders as well as the system folder, and add your own folders with FOLDERS.
• Show skipped plugins and their reasons under ISSUES, with retry, Rescan Everything and a scan log; add SKIP for plugins waiting on licence or activation windows.
• Scan Intel-only VST3 plugins and play Intel-only instruments on Apple Silicon through Rosetta; mixer insert effects require a native plugin build. Report unsupported processor architectures instead of failing silently.
• Recognise instruments from their sub-category when the plugin omits "Instrument", and choose Use as Instrument or Use as Effect by right-clicking a plugin.
• Replace MIDI clip player zoom buttons with scrollwheel zoom; minimum zoom shows the complete MIDI file even when its playback loop is shorter.

Version 0.1.850

OCT 13, 2026 · MACOS · WINDOWS · BETA

• Connect several OSCpilot controllers at once, with separate PilotNet Manager rows and disconnect controls, and send browser and waveform replies only to the requesting device.
• Show USB iPads under their system names, such as AP01 and AP02, with OSCpilot names as a fallback and separate identities even when names match.
• Send OSCpilot deck phase, colour, SYNC and MASTER feedback; stop HOLD phase correction when its momentary control is released.
• Remove Arrange and Edit OSC FOLLOW buttons; add automatic follow, independent panning, center-crossing resume, and anchored wheel/pinch zoom in Edit MIDI and OSC.
• Expand Arrange navigation with trackpad and hand panning, ruler drag zoom, Z to fit the selection, Shift+Z to fit the timeline, Home/End navigation, and arrow-key bar stepping.
• Add Edit cue navigation with Left/Right and audio energy-change navigation with Command/Control+Left/Right; move grid nudging to Shift+Left/Right and grid beat-shift shortcuts to Command/Control+Shift+Left/Right.
• Give Edit MIDI an independent playback-start marker and navigation scrollbar; clicking during playback sets the next start without interrupting playback.
• Restore arrangement waveforms for MP3 sources whose decoder cache keys include a version suffix.

Version 0.1.849

OCT 12, 2026 · MACOS · WINDOWS · BETA

Replace the CTRL companion with the OSCpilot link: OSCpilot Player on an iPad (USB-C) or the OSCpilot editor on the same computer controls the decks and shows their cues, waveforms, positions and the library browser. List the connected OSCpilot in PilotNet Manager as a CONTROLLER row, with DISCONNECT (until REFRESH) and its connection in the details. Publish each deck's original and current BPM to OSCpilot. Send OSCpilot the waveform colour source with its 3-band waveform tiles, and each deck's playback rate and timing with its position (now every 20 ms), so OSCpilot's waveforms look and scroll like AutoPilot's. Serve the browser's SEQ (sampler) source to OSCpilot and load sequencers from it. Deliver OSCpilot's 3-band waveform detail as soon as it's ready: tell OSCpilot when a deck's waveform is still being built instead of leaving it to time out, and send replies immediately rather than on the link's next 25 ms tick. Add PilotNet library sync with progress and cancellation, verified incremental media downloads, and a persistent SYNCED (LOCAL) library for offline use. Keep synchronized browser previews aligned to the master beat phase, including immediate and sub-beat launches. Preserve the live playback position when skipping beats and accumulate rapid beat-skip presses. Show wallclock mode with a lock icon.

Version 0.1.848

OCT 10, 2026

• Add multiple independently resizable automation rows per arrangement track, with saved row selections and TRACK 1 AUTOMATION-style headers.
• Add per-track arrangement filter types and Filter1/Filter2 automation for Cutoff/Resonance, Filter/Width, and LP/HP, consistently applied during playback and rendering.
• Delete selected automation points with Shift-drag and Delete/Backspace or Delete Selection, including selections without clips; preserve hidden rows and support undo.
• Reduce clicks when toggling Elastique pitch preservation with a short 4 ms blend, and smooth Cytomic parameter changes in both directions.
• Lock channel volume and input trim at 0 dB for external outputs, including controller and crossfader/Delta/vector changes; unlock both when returning to MASTER.
• Add a triangular Delta Mixer for three-deck Perform layouts, with deck isolation at each vertex and the selected fader curve.
• Correct encoding delay and trailing padding for newly imported MP3s with validated LAME metadata while preserving existing prepared tracks' grid and cue timing.
• Add single or separate per-deck VST3 MIDI outputs and channel overrides saved with the DAW session; restore MIDI clip displays when reopening the plugin editor without restarting playback.
• Keep Perform Loop playheads aligned with highlighted loop and slip-loop ranges, including ranges crossing the window boundary.
