/*
* Layer-3 of MIDI support
*
* (C) Christoph van Wullen, DL1YCF
*
*
* In most cases, a certain action only makes sense for a specific
* type. For example, changing the VFO frequency will only be implemeted
* for MIDI_WHEEL, and TUNE off/on only with MIDI_KNOB.
*
* However, changing the volume makes sense both with MIDI_KNOB and MIDI_WHEEL.
