add metronome

[jose1711]

metronome would really help beginners in "play along" mode

Interesting idea.

each track as a tempo in 0x51

probably all piano tracks will have same tempo (if no just ask with one to use)

After that, find a midi sample for methronome and include a switch to enable should be enough.
