VCO: Voltage-Controlled Oscillator
At the heart of the system is the primary sound source, a true analogue VCO, offering four output waveforms: Square (with variable pulse width), Ramp, Triangle & Sine. 1V/octave, logarithmic response.
Control Voltage Mixer
An FM sources mixer allows summing of the waveform outputs of Low-Frequency Oscillators 1 & 2, the ADSR contour, Sample & Hold (for crazy "random note" effects), and an external input, giving some interesting modulation possibilities.
Pulse Width Modulation (PWM)
The PWM Sources mixer sums the manual PWM control, LFO 2 output, ADSR contour and an external source, giving even more scope for special effects.
Also provided are a tuning control, octave switch, MIDI CV selection switch (VCO only/Off/VCO + VCF), and a real-time pitch bend control for greater expression when playing live.
VCF: Voltage-Controlled Filter
The VCF is a 24dB /octave, 4-pole low-pass type. It is this module that gives the sound the classic synth growls, burbles and wahs we are all familiar with.
The signal mixer sums together the VCO, white noise generator (for surf and wind effects, etc.), two sub-octaves derived from the VCO, and an external signal.
The sub-octaves are one octave and two octaves below the VCO signal, great for fattening up basslines, etc.
The CV mixer combines control voltages from the ADSR (+ and - sweeps), LFO 2, Sample & Hold, MIDI Velocity signal., and external source.
What's in the Box?
The RetroWave is supplied with a universal 24V dc power adapter, with several interchangeable plug tops, meaning you can use it in just about any country in the world.
