VST Instruments Zone with auto-selection enabled slows down entire project

  1. Create a new project
  2. Add 64 Instrument Tracks with e.g. Groove Agent SE.
  3. Open the Right Zone
  4. Click the * button and check Remote-Control Focus for VST Quick Controls follows track selection

Test A:
5) With the Right Zone opened, select track 1 to 16. (hold shift while clicking)
-> The tracks select but with lag, the Record Enable buttons take a while to turn red.
6) With the Right Zone closed, select track 1 to 16.
-> Instant response, Record Enable buttons color red instantly.

Test B:
7) With the Right Zone opened, select track 1 to 64.
-> The tracks select but with lag, you can see the right zone “counting” to select all instruments, then the Record Enable buttons take a while to turn red.
8) With the Right Zone closed, select track 1 to 64.
-> Instant response, Record Enable buttons color red instantly.

Conclusion: the VST Instruments Right Zone selects each instrument one by one which lags the entire project. For optimal speed, Remote-Control Focus for VST Quick Controls follows track selection has to be disabled.

Even when selecting a single track, it is a little slower. When selecting multiple tracks, it is a lot slower.
