No sequences. No loops. A generative synth that plays on by your rules. And you can play right along. Key, scale, density, complexity — just set the rules, and five machines (arpeggios, bass, drums and a sampler) keep playing, with a different phrase every time. What you shape is not a song — it is a way of sounding. No AI picks the notes: your rules and probability do. Move a slider and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. Then play right along with your own fingers. The on-screen key pad holds only the notes of the current scale, so nothing goes off-key. Play ARP A, ARP B, BASS or DRUMS, or connect a MIDI keyboard. What you play can be captured into the looper. ■ Five machines • ARP A / ARP B — two independent arpeggio engines. Ten arpeggio types, including Phrase (builds melodies) and Fingerpick (fingerstyle guitar) • BASS — a dedicated bass engine (STEP / COMPLEXITY / OMIT / PATTERN) • DRUMS — a drum machine built from probabilities (KICK / SNARE / HIHAT / NOISE) • SAMPLE — record one bar, slice it, rearrange it • Chord progressions (presets / automatic / 16 custom slots), ten time signatures, six LFOs ■ 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 64 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; play ARP A, ARP B, BASS or DRUMS • PEDAL (sustain) and a one-bar looper that records how hard you played and transposes with the chords • MIDI keyboard input (ARP A / ARP B / BASS; damper pedal, pitch bend, standard control changes) • XY pad and performance FX that work only while held ■ Sound (11 voices) • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Nylon-string guitar — synthesised with a physical string model • Marimba, kalimba, handpan and chime — struck instruments, measured from the real ones and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Filter, ADSR, five drive types, tremolo — shaped per voice • Delay, reverb, Glitch, Granular • 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, as an effect, and as a MIDI effect • Ableton Link, MIDI Clock, MIDI out (ARP A / ARP B / BASS / DRUMS), LFOs and XY as MIDI CC • External audio input (line / microphone) • Background playback — keeps playing when you switch to another app (iPhone / iPad) • WAV recording and export One-time purchase.

Verdict
The clearest difference is price: Violibration at Free against ARPJAM Studio's $12.99. ARPJAM Studio's advantage is in-app purchases (none vs 6) and update cadence (every 2 days vs monthly). On rating, ads, device support and iOS requirement there is nothing between them.
