Thanks for the replies.
The mute switch is an option for the tuner activation, I’ll give it a go. I would still prefer a program change message to disengage the tuner if possible, given the way I have things set up.
I could tune using harmonics, but I rather use the open string. As I said, it wasn’t a problem on the previous two pedals, it really shouldn’t be here (in fact it should be better, apparently).
Neither issue is a huge problem, it’s just frustrating when you do a direct swap with an H9 and these little things are different.
