Voices: DCO 1: Sawtooth, pulse with either pw or pwm. Both can be on at once.On/Off only.
DCO 2: Squarewave only. Coarse detune up to 2 octaves +/- in 1/2 semitone increments.
Fine detune +/- one-half semitone. On/off only.
Sub-osc: Squarewave, 1 octave below DCO1. On/off only.
Noise: Adjustable, 0-99. White noise it sounds like.
Brass: Actually a ring-mod osc between DCO1 and 2, on/off separate from above
(can be on without DCO1 or 2 on).
No sync options.
8 voice polyphonic.
Filter
section: Resonant LPF, non-resonant HPF. Resonance is weird, approaches
self-oscillation until res=98 then at res=99 jumps way up to
self-oscillation. Last step is a big jump. Sounds best at around 60.
Typical SSM2044 filter, i think. Gets whiny with both res & cutoff
really high. Kind of dirty sounding.
Dedicated ADSR envelope.
VCA: Typical VCA. Dedicated ADSR for volume.
Ot her: Really cool ensemble effect, MN3009 based. 1 LFO with tri,saw,square and reversible.
LFO delay. LFO can retrigger envelopes as well for pulsing effects. Routable everywhere.
Three modes: Mono, Poly 4, and Poly 8, with chord memory in P4/M modes.
Rudimentary midi, responds on Omni (although I've heard an omni off will let it respond
on channel 1 instead, haven't tried it), transmits on channel 1, only midi note on/off,
prog change, pitch bend (i think), and sequencer commands supported.
Sequencer: Simple sequencer, step entry. Syncs to midi clock, responds
to seq start/stop commands. Transposable. 8 sequences, linkable.
Interface: Two rows of LEDs in a matrix and a single big knob. Three
buttons (left, right, up/down (since there's only two rows up or down
is the same, and there's only one button). One LED/parameter and it
lights up when that parameter is active.
Overall Good synth, a little strange. Excellent chorus. Filter can be whiny or creamy or rough,
unlike many other synths I've used it seems to be very dependent on programming...
sometimes it sounds good, sometimes it sounds awful. Good bass.
