LFO

LFO with sine, tri, and TTL square outputs.

Exponential CV response. Range from 30 seconds/cycle to 200Hz.
RT1 tempco resistor optional.
Could add a CV input into U1 pin 2 for voltage control of speed.
Switch (labeled with sine and tri waveforms) selects waveform appearing at OUT jack.
Square output is TTL level (0-5v).
Bi-color LED shows polarity of output (green-yellow-red mix).
Output fed to hidden LM13600 VCA, which gets its control voltage from the MIDI Mod wheel.
