Hmm ... for info...

When I tried this out yesterday on my Linux+Wine setup with a MIDI style it worked OK apart from a very clunky transition to the new key (it sounds like drops about the last half bar and adds a beat or so before the next new bar; I think perhaps it may be trying to include a turnaround?). It's only for practice, so I think I can live with that OK, though the loss of rhythm is rather perturbing, particularly at the point where I'm also trying to read the first bar of the new key.

I've just tried to use it on my Win8.1 notepad PC at my piano, (perhaps foolishly as it's a slow PC) with a RealTrack style and it hardly works at all. It'll play the first time through, with that same clunky transition, but then it plays one chord in the new key and goes silent for the song, before doing another clunk, another chord and going silent again. I think it finally plays again the last time through the song. It seemed quite a way from random, too, mostly not playing the same four or five keys.

I changed to a MIDI style on the notepad and it's OK-ish again (though still a clunky change, of course).
