To me EOR EOC triggers/gates are good for inegrating multiple layers and events with/within envelope based rhythms. Tying a sweep of an envelope to several different events elsewhere in the system, or structurally conecting it to another sweep or wave form, etc.
In other words doing the kind of thing that Just Friends seems to be totally focused on, but arriving from the opposite direction: instead of having an envelope shape generating the EOC/EOR triggers/gates it constructs experimental envelope shapes based on the incoming triggers and gates. All the while keeping the crazy envelope shapes locked in a proportional relationship with each other, so that some form of voltage cohesion emerges…
at least that is how I am interpreting the descriptions so far. OR how I am imagining using it in the beginning of exploring the capabilities of what appears to be a pretty flexible and expansive apparatus
