I just set up a MidiMate to control my 11R. I can try to retrace my steps and remember exactly what I did. A few things I do remember:
+ I did a full factory reset. Highly recommend.
+ I have the Rack set to Omni, receive all. But it worked just fine on any single channel as well.
+ I'm using "controller mode" Patch changes on the bottom row, CC on-off (FX on-off) on the top row.
+ You must line up your presets in the 11R to correspond with the button you want to push for a patch. I don't think you can change what patch a button in a particular bank calls up. (stupid but no biggie)
+ Each of the five CC buttons (top row) must be "enabled" to send their control messages. Baffling that they would default to off, aka, not doing anything, aka worthless. ? Really Rocktron? I'm sorry I don't have a better explanation, I'll have to dig out the (almost equally worthless) manual. This part had me pulling my hair out.
+ You can save the on/off state of each CC button, for each patch, and it will command the 11R to follow, regardless of what the 11R's preset says. So if a particular patch has delay off for example, you can save the patch with delay on in the MidiMate and it will force the delay on when you call up that patch. Weird, but actually kinda nice.
Apologies for not having a better explanation, I'm super busy for the next 4 days straight, but I'll try to find time to dig out the manual and explain this better.
It is quirky and totally non-intuitive. But once you get it, it's actually very easy, and is very functional.
