I use Halion Sonic as my default softsynth. It is extremely flexible as it has an option to switch GM program changes off or on. I can load a MIDI track with GM program changes on to identify the MIDI channel and instrument patch and then turn it off to select a non-GM patch I prefer among the dozens or more available in Halion Sonic.

While Halion Sonic does have four fairly robust FX settings assignable for the audio output from any channel, I prefer to use my own FX plugins and chains per instrument, which in my DAW requires assigning individual audio outputs per channel.

As far as I have found BIAB only routes the main output of Halion Sonic, i.e., the aggregate of the channels, to the master output in the mixer. I surmise this because when you place a VST plugin after the default synth, it has no effect on the instrument voice.

I am searching to find if there is some method or preference to enable the assignment of individual audio outputs through the hosting track of the softsynth in the mixer to permit use of the plugin slots on an instrument by instrument basis.

Thanks for any input ... or, better 'output.'

Help! I've fallen up and can't get down!
