HI Michael
Eclipse FX do not have ON/OFF switches. You can "simulate" them by patching CCs to each FX level. For instance a 4 voice ModDelay may be used as a stereo chorus, with voices 1 and 2, and for stereo Delay, with voices 3 & 4 set for delays. By patching a CC to voice 1 & 2 levels you'd control your choruslevel or ON/OFF setting….and another CC patched to voices 3 & 3 would do the same for your stereo delays.
Also, keep in mind that FX spread across the 2 engines (A and B) use routings to direct audio. If routing between A and B is serial and you turn off FX in A…you may not hear the FX in B…so an accurate evaluation and setting of routings and FX blocks dry/wet values may do the trick here.
cheers
