Hi Bob,

Right, the 32-bit version would be recognized natively by Band-in-a-Box since BIAB is 32-bit, but makes no sound.

The 64-bit version needs JBridge to be recognized by Band-in-a-Box, but then it actually works.

Now that the TTS-1 is no longer available in 32-bit (JBridge doesn't allow the 64-bit version to work because it's a DXi), I'd say the SCVA is going to be the best currently available GM-compatible soft-synth for use with BIAB, but might sound a bit dated compared to modern sample libraries, since the sounds are all from 20-year-old sound modules. Those sample libraries don't support GM though, and I'd say the SCVA would sound good enough for most users, especially compared to the Coyote WT.

According to Roland's site, it has the SC-8820, SC-88 Pro, SC-88, and SC-55 sounds, not SC-8850 (not sure how different the 8820 and 8850 are), but this video does have the scat sounds:
