Well I've downloaded...I don't find the user interface easy but maybe that's just me and I can't be too critical as Pavane is doing something I wouldn't even have a clue where to be begin with...
Pavane, one MIDI I tried is one you may like to look at. It's one of The Flowing Tide (great tune BTW) I tried to knock up using Cakewalk the other day. There is a copy here.
What happens here is quite weird. The first time I open your program and load this file I get some message about polyphonic voices (whatever that means) and if I go to score, and play it, it is not as per MIDI but I guess I was warned...
If I then close the score, discard changes and re-open it, I don't get a warning but when I open the score I get a different version of the tune. Again, sadly not quite as per the MIDI.
