Lots of advice and things to try
I don't think VSC DXi will work in win7 64 bit ..

My suggestion - uncheck the 'redirect all midi to default midi synth' box

Then go to the tracks window and select one of the tracks you want sent to the Forte synth (the band)
Click the arrow for Edit DXi
in that window select the default synth position (port 32 I believe) and then assign the Forte to that port as the new default synth.
Then right-click that same track and select 'set all midi tracks to default synth' (or something similar)

Then play the song to make sure all tracks play to the Forte

go to the tracks you want sent to a different synth and right-click to change the port from 32 to one of the other softsynth ports (17-31 I think)

assign that port to the synth you want to use.

I use multiple synths often in RB and know it is possible to do what you want, just missing some setiing ..


I do not work here, but the benefits are still awesome
