Revision 2b25396, Mac Mojave. MS3 apparently keeps the Mac awake. The Mac hadn't slept all night. When I shut MS3 (and didn't subsequently touch it), the Mac started falling asleep in 10 min as expected.

This is the same bug that consumes 100% of a core. When the Piano Roll Editor is used, and a note (length) is actually altered, the app consumes 100% of a core until shut down, even if the PRE is exited, and keeps the Mac awake; if the PRE is not entered, it does neither. This is major, maybe augmented?

I can confirm on Windows too. Open Piano Roll Editor, change a note, CPU goes crazy and stays that way.

CPU goes crazy? I see one core getting busy, some 70%, bit overall the system stays at 10% (4 cores +HT).
Nice one, finally a method to prevent my laptop from going to sleep when I don't want it...
Not to say this doesn't need fixing ;-)
