Just a shot in the dark, as I haven't used the fluid engine that much.
Could you set up on single engine with the same preset sound
(instrument) on 3 different midi channels, and then set panning for
each channel via midi controller message. If I remember correctly, pan
is controller number 10, send it on the same channel used to play
notes for each voice. It also seems from the docs for the fluidEngine
opcode that reverb and chorus can be processed by the engine. It looks
like the effects can only be disabled, I read this to mean that if the
loaded soundfont has these effects enabled they will be used, unless
you disable them with the iReverbEnabled and iChorusEnabled parameters
for fluidEngine.
