My design brief was simple. To build a superb analogue monosynth for musicians using existing Oakley PCBs and to fit it all in a 4U rack. It had to be simple to operate, yet flexible enough to keep virtually everyone happy. So what has the Orbital got to offer:
Three VCOs. Each oscillator is the Oakley 'One of three' VCO with sine, triangle, pulse and sawtooth available simultaneously. An ingenious mixing system keeps the overall volume level the similar as the waveforms are switched in and out. Synchronisation is provided so that VCO 2 and/or VCO 3 can be synched to VCO1. VCO2 can have its pulse width modulated by one of the ADSRs. While VCO 3 can have its pitch swept by the envelope generator, for powerful lead sync sounds."
