greetings

please remember that...

loading a SF2 file into a(ny) plugin that supports it, including all the fluidsynth based, on a MIDI track is quite often a annoying waste of machine resources, mainly RAM, as you probably only work on a single channel and instrument/preset at a time; multi-timbral plugin instruments are here recommended to be inserted on MIDI (output) buses.

and, either way, you'll need to take care to which exact MIDI channel is which to address the intended sounding SF2 instrument preset, always.

the SFZ spec, as is, is a single-instrument per file spec. so the above doesn't really apply; though not multi-timbral in its original spec, some sfz-supporting plugins might implement some kind of multiplexing channel mapping, and thus be regarded as multi-timbral, so to speak, where each one of several sfz files/instruments is mapped to one and only one MIDI channel, just as sf2 does (ever since the late 90s, mind you ;)) such a plugin is, once again, best inserted to a MIDI output bus (and not to a MIDI track, at least in the qtractor-model-of-things(tm):)).

hth. cheers
