Before I start, this app is really great. I'm a (crap) bassist and it's been of great use.
However, when a track with a five sting bass track is loaded and lowered to four strings, any notes on that string are removed, even if it is possible to play the note using one of the other strings. Would it be possible in a future version to, where possible change notes to a different string, and possibly flag up where it can't be changed?
