Fabulous start! I am on a powerful desktop with WIN 10. Thanks for those comments. So if I understand correctly then, the way I have this set up, the sounds are produced by a synthesizer called Coyote WT.

The checked box under use VSTi/DXi Synth is directing the program to not use the generic drivers, but rather use an actual software synth program called Coyote WT (I suspect I have this available from when I used to use JJazzlab MIDI backing track creator, but it is a guess)

How should I proceed to investigate better synth options to use with BIAB? Are these freely available or do I search for and pay for a better synth to have the best sounds? Do you have recommendations?

I am learning fast thanks to you all.
