MotifPilot helps producers get past the blank DAW session with editable MIDI starters built from clear musical controls. Choose a style preset, key, scale, tempo, bar count, density, harmonic detail, humanize, and swing. MotifPilot's local, rule-driven engine builds a four-part MIDI sketch with chords, bass, arp, and melody. Preview the idea, shape the parts, try another variation, then export Standard MIDI files to share or import into a compatible DAW. Built for electronic music producers, songwriter-producers, and mobile producers: - Generate 4, 8, or 16 bar MIDI sketch starters from clear musical controls. - Work in 12 keys across all pitch classes. - Start from seven style presets: pop, house, R&B, cinematic, and three beta Trap directions. - Use Next idea to create another sketch from the same setup. - Replace a selected chord or explore chord and progression suggestions. - Develop melodies with answering phrases, breathing space, and style-specific rhythms alongside coordinated accompaniment. - Preview the same note pitches, timing, velocities, and lengths that MIDI export uses, with style-specific instruments and mix. Sounds in your DAW depend on its instruments. - Focus tracks with mute and solo controls. - Push variations such as simpler, darker, jazzier, more emotional, more sparse, more rhythmic, tension, and resolve. - Edit focused tracks with octave, transpose, quantize, velocity, duration, note movement, add, and delete controls. - Undo and redo edits while exploring. - Select individual notes from an expandable list in the track editor. - Export one combined starter MIDI file, individual MIDI files for active tracks, a plain-text DAW import guide, and a ZIP package through the iOS share sheet. - Keep saved projects and export records in the local Library on this device. - Open saved projects in Studio, export projects again, rename, tag, search, and delete local items. Batch-delete projects or exports, and batch-share exports. - Detect missing export files. Regenerate an export when its linked local project is still saved, or rebuild its ZIP archive when the original package files remain. - Recover unlisted completed exports when their local package files and recovery record remain. Review and confirm cleanup of incomplete exports in Library. - Choose system, light, or dark appearance in Settings. MotifPilot is not a full DAW, audio generator, one-click song maker, giant MIDI pack browser, direct DAW integration service, or AI prompt-to-MIDI service. It is a local-first MIDI sketching tool for creating editable musical starting points that you can import into a compatible DAW.

MIDIRack is a MIDI toolkit for iPad. Build a custom touch surface from the KB-1 keyboard suite, an all-new sequencer suite, knobs, faders, buttons and more — then unlock a visual MIDI processing graph (one time in-app purchase) and wire it into anything, from a simple custom controller to a full-on groovebox or a self-playing generative composer. Play it on its own and send MIDI anywhere, as an AUv3 plugin in your favourite host or a standalone instrument. THE BASE APP — PERFORMANCE SURFACE Design a custom control surface on a snapping grid: • The KB-1 keyboard suite — piano, diatonic chord pads, scale-locked keyboard, MPE Seaboard ribbon, MPE Strings grid (4ths), and a 4×4 GM drum-pad grid. Each is its own routable node with latch and octave shift. Successor to the KB-1 Expressive Keyboard Suite. • A suite of sequencers — drum, melody, chord, analog and CC step grids and a Matrix note grid, with a moving playhead, swing and microtiming. Per-step velocity, probability, tie and trigger conditions; pattern chaining and 4-pad scene switching for full arrangements; a knob-per-step analog machine that re-roots live as you play. • Knobs, faders, XY pads, buttons and live visualizers — bind to raw MIDI CC or graph parameters. On its own: a rich custom control surface builder — send MIDI and CC to any synth, app or hardware, no graph required. WITH YOUR DESKTOP DAW Expressive MPE hardware costs hundreds. MIDIRack turns the iPad you already own into a controller for Logic, Live, Bitwig, Cubase or any desktop DAW: • Two MPE surfaces — the Seaboard ribbon and the Strings grid send per-note pitch bend, slide and pressure to any MPE-capable instrument on your desk. • A controller that changes per track — MPE ribbon for the lead, drum pads for the beat, chord pads for the progression, faders mapped to CC for a mix move. Rearrange in seconds; save a surface per project. • Sequence it too — clock the step lanes to your DAW and drive its tracks. • Easy to connect — one USB cable to a Mac via IDAM (Inter-Device Audio and MIDI), or wirelessly over Bluetooth MIDI. No driver, no helper app. UNLOCK — MIDI GRAPH (in-app purchase) Wire MIDI In → processors → MIDI Out on a visual canvas: • 60+ node kinds — arpeggiators, scale/key quantizers, transposers, chords, echoes, swing, humanize, euclidean rhythms, random/generative melodies, LFOs, CC tools, an analog knob-per-step sequencer, a Matrix sequencer and a Counter. • Built-in instruments — Synth, Drums, a Sampler and a loop Slicer make sound right in the graph; no external synth required. • Emergence generators — Conway's Game of Life, Turing machine, Wolfram rules, Markov, bouncing balls, Lorenz attractor — for evolving, living patterns. • Presets — factory patches grouped by category (control surfaces, generators, keyboards, utilities): Amen Engine, Starfield, Conway Choir, Turing Bass, Cellular Drums… Save your own. ROUTING & MPE • MIDI Out exposes all 16 channels plus an MPE connector — multitimbral, multi-instrument setups. The built-in synth responds to MPE. • Every keyboard is its own node — process and route each one independently. PLAYS OUT OF THE BOX • Built-in polyphonic synth, drum kit, sampler & slicer or send MIDI to your gear via CoreMIDI and an always-on virtual port.
