Hello, fellow MuseScore user here.
Has there ever been an answer to this problem?
I've been trying to use Cakewalk since my Ableton free trial gave out and am stumped that I can't use my exported MIDIs like Ableton did without problems.
Besides the problem with the arpeggioted notes presented above, I also experience the first note not playing. If I redraw the note in the piano roll view, it does play.
It seems like there's some things encoded in the MIDI that Ableton understands and Cakewalk doesn't...
I saw this:
which talks about importing the instruments/tracks one-by-one. This does seem to, however tedious, fix the whole note problem but not others.
I'm about to give up on this DAW as a rendering device for compositions. Which is a shame seeing that there's no real low-cost alternative.
