CCzoom
Receives Midi Continuous Controller messages Has a CC-entry for setting a "zoom" function. This bitshifts the incoming midiCC and only updates the part of the internal value that fits the zoom-bit-depth. This allows for a "universal zoom setting", so every parameter can be controlled up to the tiniest precision.
