I believe I read someplace the plugin is designed for only one instance at a time to be open. The choke point is a background utility program that silently communicate with the main Band-in-a-Box program.
My question is with all the possible tracks that can be used in the plugin, why do you need multiple instances open at the same time?
Because we open more than one BIAB VST, we can load a style of the same type
In this way, different wavs can be generated to change the main song and chorus of the music.
I even want to open three BIAB VSTS at the same time, select the style I think is similar, and then click to generate different wavs
