I'd like to use MidiBridge to replace my Mac for running my MIDI rig. I only use the Mac for MIDI routing from keyboards to hardware synths and sequencers. I use a MOTU MIDI Express 128, but it's not recognized by MidiBridge. Is there a way to use the MOTU unit, or do you know of an 8x8 MIDI interface that will work with MidiBridge. Alternatively, if I use multiple 1x1 MIDI USB interfaces, will MidiBridge retain the synth names if I unplug the interfaces?
In order for a MIDI interface to be recognised by MidiBridge (actually it is iOS that recognises it), it must be what is known as 'USB class compliant'. Generally these sorts of interfaces don't need any drivers installed on a mac/windows system for them to work. If you had to install drivers on your mac for the MOTU then it probably isn't supported on iOS. If iOS does not recognise it then your only option is to use a different interface.
The iConnectivity mio10 or Miditech MIDIface 8x8 should both work as they both claim to be USB midi compliant. However, I am not 100% sure. My advice would be to test it out before you buy (or be able to return).
If you were to opt for a multiple of MIDI interfaces then two identical units would present themselves with the same USB credentials. MidiBridge should number the interfaces but I suspect you will need to connect each interface in the same order (but maybe not).
I'd be interested in knowing what you end up doing; if either of the 8port+ devices above work for you or if multiple instances of the same interface - or if you stick to mac too.
