- Automatically adjust the speed (as an option) so for example that if some plays very badly then the play back speed will be dropped by 20% next time through or increase speed next time through if they start playing better.
As this is an Open Source project I am not making any promises as to when this will be available.
There is a little cheat, if you are not so skilled, try changing the key signature to C, then PB will display all the sharps and flats for you.
If you find some of the pieces too easy try transposing the music into a more challenging key signature. Transposing up by one semitone is especially difficult. It is very good practice learning to play a piece of music into different keys.
