I just have BiaB defaulted to using Coyote, which is just the default Microsoft wavetable synth, from what I understand. So when I select a midi instrument, or choose to change one, these are the sounds I get. When I select the plugins tab and then select the VST/DX Synths popup, if I select Coyote as the synth, it changes nothing. Still the same sounds.

If I select another synth from the popup, like TTS-1, nothing happens. TTS-1 is dead and unresponsive and the same old voices continue to play. Doesn't matter which synth I select, this happens with all of them.

BiaB's getting weirder and weirder, so I'm trying Andrew's suggestion and deleted the preferences folder. But now my system's lost all audio -- this happens at times -- and the only way I know how to fix this is to reboot the system. So that's what I'm gonna do. But it's bed time for me, so I'll just be shutting things down for the evening. I'll give it another shot tomorrow.

Best,
Michael
