I am having an issue in finale v25 being able to edit the velocity of a note that has a diddle or flam on it. It appears as if I am actually editing the velocity of the note when I go through the process as I did in previous versions of finale with the midi tool but it won't playback properly. It continues to play at standard velocity. This also occurs if I put an accent over then note with the expression tool. The playback is at the same volume. However, If I turn human playback off it solves the issue and the playback is correct BUT without TG Tools the human playback is the only way I can get diddles to playback properly. Has anyone else experienced this issue?
