I need to replace my MIDI interface because it doesn't work with MacOS Mojave. I recently bought the IK Hammond B-X3 and I will use the MIDI interface to connect my old Roland RS-5 to use as a MIDI keyboard and a separate MIDI floor board to control the the leslie and perhaps the volume pedal.
Would something relatively simple like the iRig Midi 2 work or do I need an interface with more than one MIDI in socket?
Can I use the same MIDI channel control the B-3X leslie via CC from the floor board as I use for MIDI keyboard (the Roland RS-5), or do the need to be set to different MIDI channels?
