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.

No sequence. No play button needed. An instrument that keeps going without you programming anything. Two generative engines invent phrases endlessly inside the scale and chord you choose. What you shape is not a song — it is a way of sounding. Move a control and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. And you can play it. On the key pad or from a MIDI keyboard, right on top of the stream it is generating. What you play can be captured into the looper. Now your own sound can go in too. Record a bar into SAMPLE, the fourth machine, and chopping it up and rearranging it is the app's job. ■ Generate • Two independent arpeggio engines (waveform, filter, envelope, effects) • Eight arpeggio types, chord progressions, ten time signatures • Drum machine and bass • Six LFOs, XY pad, performance FX ■ Slice (SAMPLE) • Record one bar from a mic or line input, with count-in and click • Record the app itself (ARP A / ARP B / drums), and overdub onto it • Load audio files — and the audio from a video file • Up to 32 slices, ordered by the same rules as the arps: direction, reverse, octave, probability, groove • STRETCH (on by default) — change tempo without changing pitch • Its own filter, envelope and delay / reverb sends ■ Play • On-screen key pad — always in scale • MIDI keyboard input (damper pedal, pitch bend, standard control changes) • One-bar looper that records how hard you played ■ Sound • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Kalimba, handpan and chime — struck metal, measured from the real instruments and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Delay, reverb, Glitch, Granular, overdrive • DRIFT / FLUTTER — tape movement on the synth voices and the live input alike • Concert pitch A=415–444 Hz ■ Connect • AUv3 plug-in — as an instrument and as an effect • Ableton Link, MIDI Clock, MIDI out • External audio input (line / microphone) • WAV recording and export One-time purchase.
