I tried that, but it won't drag anything into the WAV drop (since it is not really generating audio from within the program, I'm assuming).
Specifically, what I'm doing at the moment is loading the Loopcloud Sounds plugin as a VST3 onto an otherwise blank track (no MIDI or audio). When I press play, the plugin starts running and playing back the audio of the loop I have selected. You can see the VU meter on the track moving etc. I want to get that output into another track within BiaB.
