Hi Mossy,
You need to go into sequencer mode on the Trinity and you'll get 16 MIDI Channels. The FX for each program do not automatically come over. You need to copy the FX for programs as you need them. This does not mean that you'll be able to have all of your programs using their preset fx since you'll run out of fx power. Yes, this sucks but it basically no different on any other synth out there.
HTH,
Fernando
