Click here for an audio sample of these two mods in use The patch behind this sample incorporates both mods in precisely the way I intended. The heart of this patch is a single Blacet envelope generator whose positive output is used to sweep the center frequency of a MOTM 410 filter, pan the signal across the stereo field and accelerate a pulse generator, which in turn drives another envelope which shapes the short percussive accelerando phrase. The E.G. ON mod is used to gate those accelerated pulses and the EOC (End of Cycle) pulse mode is used to trigger another single event, timed exactly when the first phrase is completed. These two events are triggered by a single gate coming from a keyboard. What's happening here: The E.G. ON pulse goes high immediately when the main envelope begins, and stays that way until that envelope ends. This E.G. ON signal is being used to open a VCA which is passing a pulse line that's also being VC'd by the main envelope, the one that's creating the E.G. ON and EOC signal. That's the first part. The second part of this mod comes into play once the main envelope and the accelerando ends. When this happens, the End Of Cycle (EOC) mod pulse goes high, which in turn triggers another ADSR which is used to gate a second event, a single note which serves as a button and quavers around an octave below tonic of the first phrase. What's great about these two mods is because they are extracted from the same envelope which is pacing the whole thing along, they track perfectly. You can slow the envelope way down, or speed it up to just a short whiz across the stereo field and all three events will fire at exactly the same point in time, every time.
