The keypad responds like an electronic organ, sustaining a note for as long as the key is pressed down. The envelope
generator is triggered by playing the keypad, and its output can modulate the filterbank via the ENVELOPE DEPTH
knob.
The keypad triggers a note with exponential loudness decay. The envelope generator is applied to both VCA and
filterbank.
The synthesizer plays a steady tone. Play the keypad to change notes. Apply slow LFO modulation for drone effects.
The sequencer walks from step I-II-III-IV in an endless cycle, producing a melodic sequence with envelope filter effects.
Fading notes are triggered in a rhythmic pattern. Press PROG-+ to add events, and use PROG-X to erase events. Play
the keypad to make pitch transitions. Activate PITCH ENV for bass drops and sound effects.
Fading notes are played in rhythm, changing pitch as the sequencer steps I-II-III-IV in an endless cycle.
