What GATOR does

  • Twenty-four synthesis models across three banks cover virtual analog, waveshaping, FM, formant, wavetable, chords, speech, granular, noise, physical models and drums.
  • An eight-slot modulation matrix routes LFOs, envelope, velocity, note, mod wheel, aftertouch, random and gate to pitch, timbre, model and level.
  • PLAY switches between GATE for held notes, TRIG for plucked percussive hits and DRONE for continuous sound.
  • You play the keys monophonically with last-note priority, HOLD to keep notes sounding, and OCT− / OCT+ for six octaves.
  • USB-MIDI and TRS MIDI in bring notes, mod wheel, aftertouch, pitch bend and knob control from outside.

Its modes

HOME
Pick one of 24 synthesis models and set HARMONICS, TIMBRE, MORPH and transposition while watching the output scope.
SCL
Set the FM, TIMBRE and MORPH attenuverters that send the internal decay envelope to those parameters.
FX
Shape the low-pass gate with DECAY and COLOUR and set the OUT/AUX mix and stereo spread.
ENV
Dial the ADSR envelope that every note starts and that feeds the modulation matrix.
LFO
Set the rate and shape of both LFOs and switch note sync on or off.
EDIT
Build eight modulation routes, each a source, a destination and a depth.
GLO
Set glide, bend range, fine tune, the MIDI channel and legato.
SAVE
Choose one of the sixteen flash slots and write the current preset to it.
