I bought an ME-50B last Saturday and only just got around to switching it on today (a break-in, day job, fitting new locks, samba band...)..
It sounds just fine in manual mode. There are preset patches which I can edit. That's nice.
I've got as far as switching between presets, which uses a couple of buttons and the pedals
to switch between them .....ok fine.
Now say I've called up the patch I like, I'm playing a song, get to the chorus and want to (say) switch on the distortion. How can I do that without switching to a different patch?
What am I missing?
