Cheat Sheet Page Tempo

Hi,

I really like the “Popular Chord Progressions in the Key of X” cheat sheets (e.g. A Lydian Cheat Sheet: Scale, Chords, Midi Files)!

A nice-to-have for these pages would be a tempo setting so that the looping playback of any of the given popular progressions could be made to play faster or slower (e.g. to practice playing over!).
