There are polyphonic tuning tones for E, B, G, D and A, enough to tune both guitar and violin. The tones last for a configurable length of time. The metronome will display beats at any tempo from 50 to 220 beats per minute, with an optional 'metronome' sound sample. And a playable mini-piano will let you play out simple melodies.
