The Microcon has one main oscillator capable of either sawtooth or square waveforms, just like the TB-303. The addition of a sub-oscillator is more the like SH-101, which can help beef up your bass sounds. The analog lowpass filter is switchable as either 2-pole (12dB/oct) or 4-pole (24dB/oct), which is better than the TB-303 or SH-101 offered. The LFO can modulate the filter cutoff frequency with either triangle or square wave and the VCO can be modulated by square or triangle waves. Simple attack and decay envelope controls and a Glide effect round out the controls. Plus a little red button to trigger it manually.
Please note that this is the original Microcon, and does not have a midi output like the Microcon II. This version only uses CV and Gate for being controlled externally. The last three photos are pages from the manual describing its operation. You can download a copy of the manual for yourself at:" [link]
