M303

Acidlab - M303

The module is a patchable synthesizer voice of the tb-303 with vco, vcf, vca and envelope generator sections. It can be controlled via cv/gate or from a sequencer such as the autobot. The analogue circuits are the same that are used in the original synth. The original transistors and closest parts are used to get as close in sound and behavior as possible. There is improved stabilization of the vco due to the use of a temperature regulated anti-log circuit.
