The 2OSC/d module contains two 1V/octave hybrid oscillators.
Each of them has
- one frequency knob plus a range switch +2 octaves
- CV input (1V / octave)
- PWM input
- SYNC input
- Sawtooth / Square / Sub-octave output
The pulsewith knob controls either the pulsewidth of the first oscillator (with the second one having a fixed pulsewidth), or via a switch the second oscillator is also controlled by the pulsewidth knob. Both oscillators can be pulsewidth-modulated independently by their PWM inputs.
The module is designed as a hybrid digital/analog module; the oscillator frequencies are determined digitally and are therefore quite stable and have a good tracking; the output wavefom itself is created analog. It's a new idea/concept that I have implemented here; the design causes the waveform to gets a bit gritty at higher frequencies (but not "digital noise") - it's the charcter of this thing!
Inputs
-
CV1 - Frequency CV for OSC 1
-
PWM1 - CV for Pulse Width Modulation for OSC 1
-
SYNC1 - Sync control for OSC 1
-
CV2 - Frequency CV for OSC 2
-
PWM2 - CV for Pulse Width Modulation for OSC 2
-
SYNC2 - Sync control for OSC 2
Outputs
-
BUS CV (2x) - located on the left patch bay it outputs the MIDI CV from the Bus.
-
Saw 1 (2x) - Sawtooth wave output for OSC 1
-
Square 1 - Square wave output for OSC 1
-
Sub Square 1 - Square Sub Oscillator for OSC 1, this is almost one octave down from the square output.
-
Saw 2 (2x) - Sawtooth wave output for OSC 2
-
Square 2 - Square wave output for OSC 2
-
Sub Square 2 - Square Sub Oscillator for OSC 2, this is almost one octave down from the square output.
Controls
-
FREQ 1 knob - Frequency for OSC 1
-
HIGH / LOW switch 1 - switch between two frequency ranges for OSC 1
-
FREQ 2 knob - Frequency for OSC 2
-
HIGH / LOW switch 1 - switch between two frequency ranges for OSC 2
-
PULSEWIDTH knob - set the pulse width of the output for OSC 2
-
PW FIX switch – in upper position the pulse width is fix for OSC 2
Patch Suggestions
The usual patch would be either direct to the filter, or via the 4/4 Mixer if you are combining more than one oscillator, noise etc.
Audio pitch modulation of filters and pitch can be really good, the latter can be FM synthesis in some circumstances.
