QUAD LOW FREQUENCY OSCILLATOR ASSISTANT

The QUAD LOW FREQUENCY OSCILLATOR ASSISTANT adds
three additional waveform outputs to each of the
four LFOs of the attached 524 module: sine, positive
sawtooth, negative sawtooth.
The four reset input jacks allow syncing of the LFO
frequency to external sources as clock pulses, gates
outputs etc. In gate mode each LFO can be gated by
external signals
