Microtonal Control?
Normally a keyboard controller will produce 1 volt per octave with each key being 1/12 of a volt change. The oscillator is designed to respond to this exponentially so that a 1 volt change will result in a doubling of the frequency (pitch). There are many people interested in other tuning systems besides the western standard 12 semitones per octave. By changing the control voltage from the keyboard controller you can achieve different tunings. The oscillator has a variable exponential input which allows you to attenuate the control signal – usually from a keyboard. The result of attenuation would be that it would take more keys to produce one octave of change. While this would allow greater than 12 keys per octave, it would not allow less than 12. This can also be done using the Q125 Signal Processor which simply allows you to amplify or attenuate a signal – in this case a control voltage from a keyboard controller.
