Coarse: Coarse tuning of the osc.
Fine: Fine tuning of the osc.
Osc 1 PW: Controls the shape of the pulse. At the center position the shape is a square.
Osc 1 PWM: Depth of pulse width modulation of the pulse shape, applied to the connected
modulation source at the input.
Osc 2 Sync: Button to turn on and off osc sync. When on osc2 retriggers for every new cycle of
osc1. If osc1 and osc2 are set too far apart in range your sound will break and can even go silent.
Osc Patch Outputs:
-
Five colors of noise outputs: white, pink, brown, green, purple
-
Separate outputs for osc1 and osc2 and the mixed osc section
-
Separate outputs for osc1 and osc2 sine shapes. Both of these sines are retriggered by
incoming gate signals (osc2 sine output disregards the sync switch parameter)
-
Outputs for the frequency information from each osc. (The frequency information chain
starting from MVC midi or the drone note, through the coarse and fine parameters and the
frequency modulations). This can be used to drive additional modular oscs for example.
Mod Gen: Modulation depth applied to the osc pitch via the tri/saw shape of the mod gen.
Env 1: Modulation depth applied to the osc pitch via envelope 1.
Osc 1 Ext: Modulation depth applied to the pitch of osc1 via an external modulation signal
connected to the input.
Osc 2 Ext: Modulation depth applied to the pitch of osc1 via an external modulation signal
connected to the input.
Osc 1: Volume control for osc1.
Osc 2: Volume control for osc2.
Osc 1 External Mod: Volume modulation (tremolo) depth applied to the volume of osc1 via an
external modulation signal connected to the input.
Osc 2 External Mod: Volume modulation depth applied to the volume of osc 2 via an external
modulation signal connected to the input.
Filters Input Crossfade: Crossfade between the hardwired filter inputs (the sound coming from
the osc section) and the filter section's external input.
Cutoff: The cutoff point of the filter.
Peak: The resonating quality of the filter.
Mod Gen: Depth of modulation applied to the filter by the mod gen's tri/saw shape.
Env 2: Depth of modulation applied to the filter by envelope 2.
Ext: Depth of modulation applied to the filter by an external modulation signal connected to the
input.
KBT: Bipolar midi note tracking modulation of the filters. At the center position no modulation is
applied. Even when drone mode is set to note, the filters will still respond to midi notes (as long as
the note input of the OS20 is connected to an MVC's note output)
