The second Input uses the following Input/Output options.
This second Input is what enables various Bump MP control buttons, knobs and the "last pad"
drum pad to "talk" to Riff.
If you look at the "MIDI Input Channel" for this Input, you will see that Input Ch 12 is selected.
This isolates the control buttons and knobs from receiving MIDI from any other channel or device
not using MIDI channel 12.
