Perfect Circuit Audio (RSS)
"The WMD Triple Bipolar VCA, the input side expansion for our Phase Displacement Oscillator. This module provides dedicated inverting/polarizing/bipolar amplitude modulating inputs normaled to the Phase Modulation inputs on the PDO.
A bipolar VCA is like a normal VCA when operated with positive control voltage. But when using a negative control voltage, the output will swing back past zero amplitude and invert the signal coming out. This produces deeper modulation than a normal VCA.
The Triple Bipolar VCA is also designed to be used as a standalone module, it does not require the PDO to operate.
Controls and I/O
+ In - This is the normal input for each VCA channel. It drives the inverting side of the Bipolar VCA. These inputs are normaled from outputs on the PDO.
- In - This is the second input for the VCA channel. Normaled through this jack is the inverted signal from the + Input. Plugging in here converts the channel from a Bipolar VCA to a crossfader, blending between the + and - inputs. When in crossfade mode, both inputs and the output are non-inverted.
CV - This input jack drives the CV knob. It can handle unipolar or bipolar signals.
Out - This is the output of each VCA channel. They are normaled to the Phase Modulation inputs on the PDO.
Bias Knob - Sets the manual gain for the VCA. Centered will have a zero output in bipolar mode, and 50%/50% of both + and - inputs in crossfade mode.
CV Knob - This knob is a bipolar attenuator for the signal applied to the CV jack. Spin clockwise from center for positive CV interactions, counterclockwise to invert the CV.
Mix Out - This output jack mixes the signals from each VCA.
Features
Three Bipolar VCAs
Normaling to PDO
Linear Response
Bipolar Attenuator for CV
Mix Output Sums All Three VCAs
Bi-color Signal LED
"-" Input for Crossfading"

"The Waverider Digital VCO is a wavetable VCO with lots of features from voltage controlled interpolation to modulated bit crushing.
Frequency The Frequency CV input accepts 0-5V control voltages, quantized to semitones, to cover the MIDI note range 0-63. It is possible to limit the CV input with the CV attenuator. The basic frequency range of the VCDO is ten octaves from MIDI Note 0 to MIDI Note 120 (8.18Hz to 8372Hz), and can be selected by the manual Frequency knob.
Detune The Detune CV input is not quantised, and allows for -5V to +5V CV to modulate +/-8 semitones. The manual Detune knob allows adjustments to be made +/-100 cents.
Waveform The VCDO section has 16 waveforms which you’re unlikely to have seen before, arranged as a wavetable. The VCDO is able to crossfade from one to the next, creating a wavetable which you can scan through under voltage control, -5V to +5V. It would have been easy to include standard waveforms like ramps and triangles, but there are many oscillators that produce those. This oscillator has its own character and provides something different.
Sub Wave As well as the main oscillator, there is also a sub oscillator with 8 waveforms. Each waveform can be selected at one of four octaves, either +1 octave (above the main osc pitch!), in unison, -1 octave, or -2 octaves. Additionally, the Sub Wave can be selected externally by CV, -5V to +5V.
Glide Waverider also includes a glide/portamento effect, glide times range from 12ms/octave to 2.4secs/octave. Turning the Glide knob to minimum switches the glide effect off. Additionally, Glide can be externally controlled by any gate source, 0V = Glide off, 5V = Glide on.
Crush The Crush knob controls the sample bit resolution of the output (ie bitcrushing). This can be reduced from 8-bit down to 1-bit in eight steps.
VCDO and Sub Osc Outputs 8-bit, 62.5KHz sample output rate. The internal waveforms and calculations are 8-bit, and new samples are output via the on-chip PWM modules at 62.5KHz. The PWM modules’ outputs are at 125KHz.
Features
Wavetable VCO w/ Voltage Controlled interpolation
SubOscillator with Voltage Controlled waveform and octave changes
