Triwave Picogenerator pictured

Triwave controls:

* Two tone generators (VCO's), each with:
o Pitch: center frequency from rumbling low to hissing high
o Tone: select harsh square-wave or smooth triangle-wave
* Three LFO's (low frequency oscillators), each with:
o Speed: rate of change of each pitch channel
o Depths (2 knobs per LFO): Amount of pitch modulation on each VCO
* Mix: blend between tone channels
* Volume: output level


"The Essential" Triwave:
* All of the above, plus...
* Waveshaper: (3 knobs) blend each LFO from square to triangle
* Ring mod: adds an input jack and sensitivity control for ring modulation effect
* Dual cross modulation: (2 knobs) frequency modulate each channel with the other

"The Works" Triwave:
* All of the above, plus...
* Waveshaper: blend each LFO from square to triangle, a knob per LFO
* Symmetry: blend each LFO from sawtooth ramp-up to triangle to sawtooth ramp-down, or variable duty-cycle rectangle wave, a knob per LFO
* Ring mod: adds an input jack and sensitivity control for ring modulation effect
* Aux volume: uses ring mod input jack for blending clean signal over the triwave
* Dual cross modulation: frequency modulate each channel with the other, a switch per VCO
* Range switches: select full pitch range or high range only, a switch per VCO
* Drum triggers: adds a trigger input jack and sensitivity knob per VCO, for triggering each channel with an external source
* Expression pedal jacks (pitch): control pitch of each channel with an expression pedal
