VCO

Full featured oscillator

This design was originally inspired by classic sound of the Mini's VCOs.The basic core of the oscillator is very similar, but many other things have been improved upon. For example, the exponential convertor uses modern day parts and the temperature compensation is provided by a high quality +3500ppm/K resistor.

Four output waveforms are provided simultaneously; falling ramp sawtooth, triangle, pulse and sinewave. Output levels are 10V peak to peak, in common with most modular systems.

Apart from the usual fixed 1V/octave modulation inputs, a fully variable exponential input is available as well as a fully variable linear modulation input. Slave synchronisation is easily obtained by inserting a falling sawtooth waveform into the SYNC input. This input is level sensitive to allow different strengths of synchronisation. A front panel pot is provided to control the depth of the effect.

The pulse waveform can be modulated in two ways. You can have either 'centred' or 'edge' modulation styles. The former will modulate both edges of the pulse output. The latter modulates only one edge. This can have a profound effect on audio rate PWM. The selection is implemented by a simple switch on the front panel.

The pulse output features a useful method of maintaining average output level. This means that fast sweeps of pulse width no longer produce any audible clicks as they do on other VCOs you may have used.
