I think I’ve uncovered another little problem with how this works.
Here is the situation.
Starting point is Jamstix unloaded due to it being bounced.
I disable the bounce to deep edit Jamstix.
I make some changes within Jamstix perform an offline bounce and unload Jamstix.
If I do this again, the changes I just made to Jamstix are gone.
I’m not sure if I save the project prior to bouncing the track if it would help.
