Everything you need to create
🎵
Original Sound Engine
ToneField Classic — a pure sine wave synthesis engine forensically crafted to produce a unique, warm tone unlike anything else.
🎲
Generative Probability
Set per-column probability so patterns evolve differently on every loop. No two performances are ever identical.
🎹
13 Scales, All 12 Keys
Major and minor pentatonic, all 7 modes, harmonic minor, melodic minor, whole tone and diminished. Change key instantly.
Live Recording
Record your live performance as a WAV file — capturing every probabilistic variation and delay in real time. Drag straight into Logic Pro.
🎛
MIDI Integration
Export patterns as MIDI, or send live MIDI output to Logic Pro, GarageBand or any DAW as the pattern plays.
🔊
Delay & Effects
Built-in delay with time, feedback, filter and mix control. The default 372ms timing locks beautifully at 80 BPM.
Transform Tools
Flip horizontal or vertical, rotate, shift in any direction, or randomise your pattern instantly.
💾
Pattern Storage
Save up to 8 named patterns. Export as WAV, MP3 or MIDI. Your work is always preserved.
