The GMS-782 Dual Voltage Controlled Low Frequency Oscillator/VC Amplifier provides low frequency triangle, sine or square waves for use as modifiers or triggers for complex evolving synth patches. Two functions, commonly used together are combined in each channel to produce a versatile voltage controlled waveform generator. The LFO has a wide range from subsonic to low audio in two ranges and provides a trigger function to reset the oscillator to a known state. The voltage controlled amplifier has a selector switch allowing one of the three oscillator waveforms or an external input to be selected as its input. The output is a function of the front panel level control summed with the voltage control input.
TRIGGER- When a control signal with a rising edge is presented to the Trigger input, the oscillator is reset to 0 Volts output and the waveform starts rising in the positive direction. The trigger input signal should be a 0 to +5 Volt signal. The length of the trigger pulse is not important.
