What it does
41 waves per oscillator
All 41 waves are band-limited. On a 2.6 kHz saw, aliasing stays more than 85 dB down.
Unison with analog drift
Each oscillator plays 1 to 10 unison voices with detune and drift. Polyphony runs from 1 to 32 voices.
15 filter types
Low- and high-pass at 6, 12, 18 and 24 dB, band-pass, notch, peak, a vowel formant filter and 24 dB ladder modes.
A stereo trance gate
16 steps with separate left and right patterns, synced to the host's song position at speeds from 1/4 to 1/64.
Arpeggiator and modulation
8 arp modes including chord, 1 to 4 octaves and hold. 3 LFOs with 7 waves sync from 8/1 to 1/64, and 3 ADSR envelopes take bipolar amounts.
A preset librarian you can search
Three columns with search as you type, favourites, history and a count per category. The interface scales from 50 % to 200 % and has multi-step undo.
