Hi, I would like to request to add the possibility to change the playback pitch without transposing the chart. I very frequently play instruments which aren't tuned to A=440, but a bit higher or lower than that. Once I do, I can't play with the app anymore..

I would appreciate very much the addition of this feature - the ideal would be a box that allows me to choose the Hz for A between 380 and 470.

Many many thanks!
