Hello daerp1
At the time, I created some custom consoles for Performer 5.5. They were meant to be used with Roland M-GS64 and Yamaha MU90R, to automate their volumes, internal effects and a bare minimum editing (CC#71, 72, 73 and 74).
As far as I know those consoles can be imported into Digital Performer 9, although I haven't done yet.
At present I've never created any MidiDesigner layout, mainly for a matter of time.
In the begininnig I bought MidiDesigner because I would have created a custom control for my Roland JX-10, then I found an already done layout, thus I gave up developing my own one.
