OS X 10.9.5
Reaper 5.18
To reproduce:
- Add heavy (memory-intensive) FX instrument to track.
- Add another track and add a heavy instrument there too.
- Repeat again.
- Add a new blank track.
- Undo.
Expected behavior: Undoing "add track" is about as quick as adding the new track. After all, there's nothing in the new track.
Actual result: Undo takes a long time as some/all of the instruments in the project reload.
