/**
 * A Bitwig2-compatible version of TomsGenericKeys
 * (original at https://github.com/ThomasHelzle/Toms_Bitwig_Scripts/blob/master/TomsGeneric/TomsGenericKeyboard.control.js)
 *
 * Enhanced Generic Controller Script with Support for
 *  - all 16 Midi Channels + Omni
 *  - CCs 1-119 fully mappable...
 *
 *  (!) Bug?: Omni is currently not working - channel-specific note inputs seem to 'mask' the Omni.
 *            Vice-versa, if Omni is defined *before* channel-specific inputs, the channel-input are silenced.
 *
 * Current verson at:
 * https://github.com/justlep/bitwig/blob/master/tmp/GenericKeysV2.control.js
