I figure it's best to start a new thread rather than address these in some of the others. I spent most of the day testing various issues in Finale 26.3, 27.1 over Monterey. I used copies of an orchestration that I commissioned from my daughter that she did in 25.5.
You’ve probably seen my post about the dual Lyrics folder. This only happens when updating from within 27.0 and not from any of the stand-alone installers (27.0, 27.1 Beta, 27.1 Release) Removing the spare Lyrics folder doesn’t seem to affect anything on my system. No big deal.
Of concern is that NotePerformer 3.32 exhibits different behavior in 26 and 27.1 — between the two, I can get it to work properly (assign instruments in 26, then open the .musx in 27.1 to access the mixer which I can’t do without having done the assignation in 26 first). Ok… I already had 3.32 installed since Catalina. However, when I reinstalled NP 3.32, Both 26 and 27.1 crashed and reinstalling could not bring either back to life.
The only way to restore functionality is to restore my iMac to a state before the NP re-installation (again, NP 3.32 was already installed before I upgraded to Monterey). Fortunately, APFS Snapshots lets me do this in about 2 minutes as long as I select a Snapshot within the last 24 hours. Because of this, I was able to duplicate this issue with absolute certainty and have send the latest crash reports to MM Support.
If you don't know about APFS Snapshots on the Mac and its near instant restore functionality, this is a good source.
I may have discovered another weird anomaly in audio exported from NotePerformer as .wav. over Monterey. If I can duplicate it, not pretty. Exporting as .aif is not an issue. If you're used to working in .wav as I am, there are a number of converters out there but QuickTime and AppleMusic can do the conversion for you free — the raw audio is untouched. Conversion from .aif to .wav strips and rewrites the file headers.
I will report when I have time to look at this again.
