The BK-7m has got several midi user sets, in which you can store all midi settings. I think it is the same with the BK-9. So you could prepare two such sets and wouldn't have to go into the depth of detailed midi settings each time. It should be accessible rather quickly by pressing a few buttons.

If you need to switch and route a lot of different midi signals, the app 'iMidiPatchbay' for iPad is very sophisticated.
