Thanks Jim, this will come in handy in the future.
Pipeline,
I will try out polyphone see if I can get some decent results with it.
That symbolic link tool sounds very interesting!
I'm already familiar with Viena. Used it lots of times to compile my final GM SF2 which is a combination of the Magic.SF2 and the Mysing Kite SF2. The latter I think is the best (warmest sounding) GM soundfont.
https://www.kvraudio.com/forum/viewtopic.php?f=42&t=351893&start=120Using a good SF2 will in some cases sound better than using DXI Forte for instance, however you cannot directly render MIDI tracks in BIAB this way. I've been using the program SoundTap for this to record these tracks manually, which is quite a workaround I think.
The best thing would be to somehow convert the GM soundfount to DXI somehow (not a clue how to do this).
