Using quarter / half and whole notes in the same staff.
When I am using a mix of half and quarter notes, it wants me to use either quarter or half notes, not a mix within one chord.
One work-around I do is to first create the first chord, than the second. If in the second chord there are notes that should continue, instead of being played twice, I right click the quarter note in the first chord and change the S to a half note, then I delete the quarter note in the second chord, but then it forces a rest on me, so then I right click the rest key and make it "hidden".
It works for now, but of course the midi file plays it wrong.
Please let me know who else has had an issue with this.
