The Erica Synths Black series VC EG (voltage controlled envelope generator) and expander bring a unique trick or two to the envelope world and to be blunt are just ace! There’s tweak knob responses so the times scale from 0 seconds to 1.5 seconds at 12 o’clock on the knob then from 1.5 seconds to 12 seconds full clockwise. The expander adds a unique CV mode that breaks out the envelope stages into independent CV sources. This is different from the logic mode that gives us a gate outputs while that stage on the envelope is active as each output is variable. The attack output (in CV mode) will rise from 0 volts through the attack time and shape set on the module and then as it hits the decay stage that voltage drops to zero. The decay output then immediately rises from being inactive at 0 volts to full voltage and decays in line with the decay time and so on. This is a long video as it really opens lots of opportunities with the features mentioned and a few other bits.
