Feature like play metronome to every eight note (8 times in a bar).
This would verify that all riffs are played right. Normally it plays
to every quarter note.
In very very slow tempos might be handy to play to every 16th note
i.e (16 times in a bar).

Normally metronome is used during recording. But this metronome feature
might also be good training tool during playback.
