DESCRIPTION:
Mods include an LFO with pulse and continuously variable saw up/triangle/saw down outputs, with a LFO range switch that takes its speed well into audio frequencies.

On each of 4 channels theres a percussion decay long/short/constant tone switch, VCO frequency modulation source switch (audio or LFO), LFO waveform switch (pulse or saw/tri), VCO FM amount knob, and a VCO pitch range hi/low switch.

The VCO frequency of each channel can be modulated either using the LFO or the output of the overall audio source selection switch. This rotary switch chooses between sourcing the audio modulation signal from the output of any of the six channels, including the channel being modulated for FM feedback loops, or an external audio input.
