wow... you've got some pretty rockin rhythm skills there Thanks! I just upgraded my pyAno and I love it Do you mind if I make a small feature request? As far as I can tell, the black bar shifts to the lower octave and the white one shifts to the higher octave. Would it be possible to make them both white and then have one of them colored in depending on what octave you were in? So, for example, if you're in the lower octave, the left button is black, and when you click on the right button (white), the piano shifts to the upper octave and that button turns black while the left one turns white. Looking back on that I realize that I'm being clear as mud Hopefully I sort of communicated what I wanted to, if not, don't worry about it! Thanks for a great program!!
