I love the magic 8ball spinning wheel in the tuner.
Man, I've just never gotten on with the tuner in the Axe. Especially trying to use the MFC's display. Enough so that I run 9V power to my board just so I can keep a TC PolyTune2 on there. Frequently with my PRS I don't need to tune between songs, so it really is "strum, (don't) tune, rock." I've noticed I can verify my entire guitar is in tune before my band-mate is past one or two strings, and if I do have a string that's out I can go right to it.
(I was paid $10,000 to make this statement. Har-har.)
Wait, but we were talking about the metronome in the Axe, not my fanboi love of the TC PolyTune.
Q: is the ability to turn on/off the metronome with a midi CC new? It seems like I was looking for that a few firmware revs back and it wasn't possible. Or I was looking in the wrong place.
