TORONTO, Ontario - July 11, 2018 - North Coast Synthesis Ltd., Toronto-based manufacturer of electronic musical instruments, has extended its line of discrete-transistor utility modules with the MSK 012 Transistor ADSR, an envelope generator for Eurorack synthesizers. With only nine transistors it generates a complete four-stage envelope suitable for simulated acoustic instruments and classic synthesizer sounds.
'The fun thing about an ADSR circuit is that there's a lot of scope for creativity,' says North Coast module designer Matthew Skala. 'If you look at schematics on the Web, or the commercial products out there, the front panels may look the same but each one is totally different inside. It's not like a mixer, where everybody uses the same techniques. So the details matter in an ADSR. For me that meant putting in a Schmitt trigger input, so it doesn't need a well-behaved gate signal, and going for conductive plastic on the panel pots.'
