Currently using a Nova System but it doesn't have enough preset locations for me. Thinking of switching to an M13 to use in Scene mode, so I'll have 12 presets. How transparent is this unit? Once the Nova is tweaked, it's pretty transparent, can the M13 get there? Also, does anybody know if you can change what number MIDI Program Change goes out per Scene? I need 3 different PCs to switch the channels on my amp and I'm not sure if I can do this with the M13 which would be a big shame. It seems like they send out 0-11 and that's it? Oh, and does it send CCs too? Need those to switch my FX loop in and out.
