It has good functions, but lacks synchronization between the metronome and the YouTube player -
would be perfect.

good features, but echo what other review said. transpose shouldn't have to sound like crap, let it change tempo (a full octave transpose would also change to .5 or 2x speed etc). Also couldn't get the looping feature to work, but maybe that's just me.

works as advertised, but i wish there was a way to adjust tempo and pitch at a synced rate, to avoid the choppy static sound. like the "change speed" setting in audacity or like playing a real record/tape at a different speed.
