Now let's go through the parameters one at a time.
9.10.2.1. User Channel
This sets the keyboard MIDI Channel. It's the same parameter found on the keyboard that
is set by holding Shift and pressing a key.
9.10.2.2. MIDI Input Channel
This parameter allows you to perform MIDI-to-CV conversion when the Sequencer and
Arpeggiator are stopped. The selected value is the MIDI channel that will be allowed to
control an external device through the CV/Gate/Mod connectors.
These MIDI messages can either arrive via USB or the MIDI Input connector.
9.10.2.3. MIDI Thru
This parameter will turn the KeyStep 37 MIDI Output into a MIDI Thru. Incoming MIDI data
will be routed directly to the Output instead of being used to transpose sequences, etc.
