MultiTrack DAW

Perfectly Simple Multitracking

MultiTrack 7 is here: all 32 tracks for everyone, MIDI, surround to 9.1, crossfades and fade curves, automation right down to the tempo, and time stretching. The power of a digital audio workstation in the palm of your hand. MultiTrack has been recording on iPhone since 2009, and version 7 rebuilds it from the engine up — with all 32 tracks for everyone. RECORD Record from the built-in mic, any USB or multichannel interface, or an AUv3 or Inter-App Audio instrument — up to 32 inputs at once. Monitoring, Auto Input, punch and loop recording, and latency compensation tuned to your own setup: tap Detect and a short chirp measures it, or set it by hand to the sample. Recorded audio lines up with what you heard. EDIT WITHOUT LOSING TAKES Nothing you record is overwritten, and a take survives a call, a lost interface, or a closed song. Regions point at the audio, so slicing and trimming never touch the file. Regions can overlap, and the overlap is the crossfade. Drag one over its neighbor to blend two takes — eight curve shapes, equal-power or equal-gain. Every fade has a curve of its own: drag a fade handle up or down to bend it. Smart Snap throughout, and 100 levels of undo. TEMPO AND TIME Change time signatures on the ruler, wherever your song requires. Automate the tempo itself (Unlock All Features): draw ramps and curves, and audio, MIDI, and Ableton Link follow in real time. MIX Up to six AUv3 or Inter-App Audio plugins on every track, bus, and the master. Four send busses, pre- or post-fader. EQ and compressor throughout, plus bundled delay and reverb. Sidechains from any track or bus. Freeze a track to reclaim CPU. SURROUND, DONE PROPERLY Stereo, Quad, LCRS, 5.1, 6.1, both 7.1s, and 9.1, plus discrete pass-through from 4 to 16 channels. The panner places sound instead of smearing it: at least 24 dB between neighboring speakers in every layout, and constant level across the field. Switch a speaker off and its share is redistributed, not dropped. MIDI Play AUv3 instruments from hardware controllers, Network MIDI, or other apps, and record every note, loops included. Route it all through the MIDI Matrix with savable filter and transform chains, and import Standard MIDI Files with their tempo maps. Unlock All Features adds piano-roll editing, where Draw mode puts a note under your finger. AUTOMATION — Unlock All Features Draw or record automation for volume, mute, pan, EQ, compressor, sends, pitch, any Audio Unit parameter, and MIDI CC, pitch bend, and channel pressure. MIDI 2.0 goes further: every note carries its own pitch bend and pressure, shaped note by note with a bendable curve on every segment. WARP AND PITCH Pitch shift up to two octaves either way, with formant preservation, no unlock needed. Time stretching and warp editing (Unlock All Features) put source and target timing in one editor: place markers, correct a source BPM, and loop while you audition. EXPORT THAT SOUNDS LIKE YOUR MIX WAV, MP3, FLAC, Apple Lossless, AAC, and Ogg Vorbis. Normalize only if you choose, to a ceiling from -6 to 0 dBFS. Real dither, triangular or noise-shaped, applied after sample rate conversion, where the depth actually drops. Export the song, the loop, stems, or one surround mixdown. FILES AND iCLOUD Projects live in iCloud Drive or on device. Drag audio, MIDI, presets, and projects in and out of Files and other apps, or over Wi-Fi. No account, no tracking, no analytics. SPECIFICATIONS 32 tracks, 32 inputs, 16 outputs, 16 channels per track. 16-bit, 24-bit, and 32-bit float at 44.1 to 192 kHz. AUv3 hosting, Inter-App Audio, Ableton Link, external MIDI Clock, hardware and Network MIDI. UNLOCK ALL FEATURES Adds three things: MIDI editing, time stretching and warp editing, and automation. Everything else is part of the app, all 32 tracks and pitch shifting included. Subscribe with a free trial, or buy once and keep them forever. Bought extra tracks in an earlier version? What you spent comes back as free months of Unlock All Features and a lower one-time price. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ harmonicdog.com

MultiTrack 7 is here. Thanks for waiting. This is the big one: a new audio engine, a new timeline, and a mixer that runs all the way to 9.1 surround. Your projects from earlier versions open in it. EVERY TRACK, FOR EVERYONE All 32 tracks are now part of the app, whatever you bought before. If you paid for extra tracks, that money comes back: open Options > Upgrades for free months of Unlock All Features, and a lower price on the one-time purchase that keeps it forever. NEW - MIDI tracks and clips, a piano roll with Draw mode, the MIDI Matrix, filter and transform chains, Network MIDI, and Standard MIDI Files with their tempo maps. - MIDI loop recording: each lap is a take of its own, new notes join the clip they land in, and tapping overlapping clips cycles through them. - MIDI 2.0 per-note pitch bend and pressure, each in its own lane with a curve on every segment. Drag a handle to bend it. - MIDI Panic, in the file menu, stops stuck notes on every MIDI destination. - Automation for volume, pan, sends, EQ, compressor, pitch, and Audio Unit parameters, plus MIDI CC lanes. - Tempo automation: draw ramps and curves, and audio, MIDI, and Ableton Link follow in real time. - Time signature changes anywhere on the ruler, as many as a song needs. - Time stretching and warp markers, and pitch shifting up to two octaves with formant preservation. - Surround and multichannel, from stereo to 9.1 and 4-16 channel pass-through, with a panner that keeps at least 24 dB between neighboring speakers. - Region crossfades: overlap two regions and the overlap is the crossfade. - A curve for every fade. Drag a fade handle up or down to bend it. - Recording latency calibration. Detect measures your mic, speaker, or interface with a short chirp, so takes land where you played them. - Ableton Link and outgoing MIDI are timed to the speaker, Bluetooth included. - Input monitoring stays silent on the one route that can only feed back, the built-in mic and speaker. New songs start with it on. - Takes that survive: a call, a lost interface, or a closed song ends the take and keeps it. Playback stops when headphones, AirPods, or a USB device disconnect. - Six plugins per chain on every track, bus, and the master, and four send busses. - Exports with real dither, and Normalize is now a choice, with a ceiling you set. - iCloud Drive projects, the Files app, drag and drop, and ZIP browsing. - Light, dark, and custom themes. - German, French, and Japanese throughout, and a help guide that works offline. - MultiTrack asks for the microphone when you arm a track, not at launch. - No account, no tracking, and no analytics or crash-reporting service. UNLOCK ALL FEATURES MIDI editing, time stretching and warp editing, and automation come with Unlock All Features: a subscription, or a one-time purchase. Everything else, pitch shifting included, is part of the app. REMOVED - Audiobus. A song saved with an Audiobus input opens with no input selected. - Wi-Fi mixdown and track downloads. Wi-Fi still carries projects and audio files; send finished mixes out through Files, AirDrop, or the share sheet. - The speaker button on plugin windows. AUv3 instruments are always heard; use Mute to silence a track. Found something? harmonicdog.com
