Ok...

Like I said U can only do it for Hallion...

click edit 2 c the vst i pannel....

On the main Pannel (MACRO) u have on the bottom 2 yer left a little pannel 4 the midi channel, next 2 it u have another 1 saying OUTPUT... so here u choose 1 of the many output available...
U can have a different output 4 each midi channel...

If by per chance U need the same sound but with different notes on different outputs, just use the same sound on diferent channels...

That's it... let me know If u r sorted now...

4 absynth or FM7 all u do is open more than 1 instance of each... if it's the same sound .. just use the same preset (or user patch)..
