Dual LFO module, 75x200 mm, with four knobs and six jacks

This is a dual LFO synth module in Kosmo format, based on a Kassutronics design . There are three outputs for each LFO. Depending on the shape pot setting these provide ramp, asymmetric triangle, symmetric triangle, or sawtooth waveforms; sine or skewed “sine” waveforms; and narrow, square, or wide pulse waveforms respectively. I chose to replace the original JFET-based tri to sine converter with a dual BJT design.

(On the panel it says “Analog Output” but really the design should be credited to Kassutronics.)
