The output driver is Microsoft GS Wavetable,and the Sybth is Coyote Wave table DXi. When I play the MGU file in BAIB, then Use VST/DXi Synth must be unticked, otherwise there is no sound from the track. When I save the file to MP3 or WAV, BB insists that the Vst box be ticked.
I'll clarify "synth" here before I start. We are not talking about the Moog-type synthesisers that make the 'synthesiser sounds' we know. We're talking typically about sound engines that use samples of instruments to build a passable-to-good sound of any instrument, traditional or synthesiser.
I think the "Microsoft GS Wavetable synth" is about as 'legacy' as one can get (Win98 I think). I set the output driver to "
no MIDI driver", or whatever the words are, and use the VSTi/DXi synth and I'm pretty sure most people would use BIAB that way.
CoyoteWT is the default synth bundled with BIAB, will render OK and sounds OK but not great. There are better synth available, one is even bundled with BIAB but rather hidden away.
I suggest sticking with CoyoteWT whilst you find your way around getting MIDI to work for you, then probably exploring other synths in the future. The one bundled is VSTSynthFont and you'll find instructions in the BIAB manual. It uses a soundfont and there are a number available on the 'Net, mostly free.
Where using a
MIDI driver may be useful is if you have a hardware MIDI->audio generator that you would prefer to use, rather than the VSTi/DXi. Then you would set the driver to control that hardware device. Be aware, though, that BIAB itself will then no longer render, the external hardware will, so you would need to record the output from that hardware.
