Because other VSTS can be placed on multiple instrument tracks.

So I'll try to open two BB VSTS today

The following problems occurred:

1. The sound burst is more serious
2. There will be generation errors. For example, I didn't check lead in, but lead in will be added to the front, but the chord track starts again. Therefore, there will be incomplete chords and generation errors
3. If the point is generated at the same time, it will get stuck and the computer will crash. Daw must be forcibly turned off
4. If three BB VSTS are opened at the same time, it will directly jam and crash

------------

I use plug-ins from other companies. Sometimes more than 10 will be opened at the same time, and there will be no problem.
Therefore, the code architecture of BB VST plug-in itself may be different from that of other companies.
This is my guess.
