Low Frequency Oscillator
This is based on
the Korg MS20 LFO.
This is a standard
utility LFO with 2 variable waveshapes and 2 speed ranges, output
one is a variable square wave that goes from 10% to 90% and output
2 goes from saw-triangle-inverted saw, the two speed ranges can
be adjusted by changing 2 capacitors.
I have also re-designed
the panel for this, but have not had a chance to make a new one.
