These are bugs that either always or occasionally manifest in the current version (1.0.0) and that I’ll endeavour to fix in the next release (1.1.0).
1. (Occasional) One of the hands remains resting on the leg even though it is trying to play notes
2. (Occasional) Arms (briefly) deeply penetrate each other when the arms are crossed
3. (Always) MIDI Files with non-western (more accurately, non-Latin1) characters in the name can’t be opened
4. (Always) Duplicate file names in the playlist cause the highlighted file to be the first with the selected file name
