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.
