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.
