When modulating decay times with control voltages it is good advise to keep the voltage fixed while the envelope is developing. For example trying to modulate the decay time with an audio rate signal does in general not produce sensible results. A S&H is integrated into the module to sample the decay time modulation input signal (S&H IN) on every new gate trigger. This way the modulation amount will stay fixed until the module is triggered again by a new gate pulse. The full sampled signal is sent straight to the S&H OUT, so it can be routed to an input of choice on ENV A or use elsewhere, but is attenuated using the ENV B MOD knob before being sent to the ENV B DECAY function.<ref name="rh" /> |
