4024 Sub Osc

ramp->square two sub octaves -1/-2 and -3/-4 down

Sub oscillator circuit is based on 4024 cmos IC. It generates square waves based on the output from another oscillator. It has 2 sub octave outputs and each output has an octave switch to select the sub octave; -1,-2 and -3,-4. Oscillator input also has a buffered output so the input signal can also be used from the buffered output. It is very simple and cheap to build.

Front panel is also made out of PCB and screen printed by hand.
