I can access the BIAB plug-in in Ableton Live 10, both VST and AU on my Macbook Pro running Catalina 10.15.3

I can drag from the VST plug-in and it asks me whether the track is harmony, solo or drums to convert to MIDI. I selected the appropriate one and it appears to be working but ultimately nothing shows up in the timeline in Session view in Ableton Live 10. It appears they are there in arrangement view but nothing is there.

Same thing if I use the AU plug-in, either dragging single or multiple tracks.

Suggestions?

Thanks!

Hmm... I just tried it in in Live Lite 10.1.7 with the AU version and it works here, I can see and hear playback of dragged tracks in both session and arrangement views.
Then again, I'm still running Mojave so maybe some Catalina users, or maybe even PG folks will chime in.

Sorry I couldn't be of more help.

The plug in causes Ableton Live 10 to freeze when dragging and dropping tracks.
I'm using the latest versions on Windows 10.

Seems to work fine in Reaper.
