ITs important to remember that the minimoog had ADS envelopes (In other words Decay and release shared the same setting). Bear this in mind when programming authentic minimoog sounds. You can make some pretty good minimoog sounds on the virus......dont be afraid to use the onboard eq and osc distortion.
