Ta mate,
What i think am going to do is to keep the Midi-Volumes on the EMU right up at 127 value, but tweak the volumes (where needed) via the AMPLITUDE page (so using the +/-DB settings).
i think i got all the Midi stuff sorted to start getting me up and running now (like the Program Changes etc). i am really lovin' the External Controller Section on the Nord and the two instruments are sounding quite good together now. i also Midi up my Roland JV1080 sound-module and tried Layering some Orchestral sounds with the samples on the Emu, which was quite interesting.
But what i am thinking of doing is splitting the Nord and having the right-hand zone for sounds on the EMU (like Brass), and the left-hand zone for the JV1080 (Bass). The Bass sounds on the JV1080 are way better than the ones on the Nord (for what i want anyway), as it has Fretless, Jaco, Slap, Acoustic plus TONS of complex Synth Basses.
So really i would just be using the Nord as a CONTROLLER !!
