The Biab Plugin now has it's own forum.
The plugin is identical to the Win version though I was getting a lot faster generate times in the Mac plugin on the same hardware (but don't tell the Win users that) it is also ahead in development (for a change) it's using the 64bit app in the background whereas the Win is still using the 32bit app.
Hopefully the MacBB 2020 will be released a bit earlier next time round that all the hard yards are done to get to 64bit.
It has come a long way from the original Win Beta that took minutes to generate a song now I get it in 11 secs along with synced playback.
