I love so much that @peter has given us some new features related to multitracks. Thank you!
Maybe this already exists and I don't know it...One thing that would be helpful is to have a way to set some tracks as not-pitch-transposable. For example, if drums, click, and guide tracks could be left as is while the other tracks move a full step down, etc. I believe WorshipBand does this by having you upload a markup document to indicate which tracks should not be pitchable. You could include this in the folder of tracks perhaps.
thanks again!
