Add a User MIDI map for users to configure their own MIDI messages against mappable Reliq controls (as defined in the External Devices section of the manual.
Allow users to set their own MIDI messages for the mappable controls. This will allow MIDI controllers with fixed CCs etc to be mapped to those MIDI-exposed parameters. e.g. So that User MIDI CC 44 can be mapped to Reliq MIDI CC 20 Pitch offset, where the users' MIDI controller (or maybe hardware synth) is fixed to CC44 on the knob they want to use.
