MIDI files exported by MS4.01 not playable on Kawai CN37 piano

• Jan 24, 2023 - 01:56

I used MS3 to generate .mid files of piano accompaniments, playing them on a Kawai CN37 piano. I attempted to do the same with MS4.01, and the piano reports "no compatible files found." The new .mid file (exported from MS4) plays correctly in Windows Media Player.

MS3 (Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit):, revision: 3224f34)
MS4 (OS: Windows 10 Version 2009, Arch.: x86_64, MuseScore version (64-bit): 4.0.1-230121751, revision: 9b70a8c)

Files were copied to a flash memory stick which plugs into the piano. The same flash memory stick contains several .mid files that were exported from MS3, which are played correctly by the piano. The file exported from MS4, plays correctly from the memory stick using Windows Media Player.

MS3 will not open the MS4 file (as expected). Looking for a direct comparison I tried to copy some of the MS4 notes and paste into MS3, but MS3 does not accept the paste.
