Each MIDI channel consists of 128 notes (n additionally each have a pressure control, 128 CC's (numbered likewise), a channel pressure control (also called 'channel aftertouch') and a pitch control which may all be mapped to individual MIDIMonster channels. +Every MIDI channel also provides `rpn` and `nrpn` controls, which are implemented on top of the MIDI protocol, using +the CC controls 101/100/99/98/38/6. Both control types have 14-bit IDs and 14-bit values. + Example mappings: ``` midi1.ch0.note9 > midi2.channel1.cc4 midi1.channel15.pressure1 > midi1.channel0.note0 midi1.ch1.aftertouch > midi2.ch2.cc0 midi1.ch0.pitch > midi2.ch1.pitch +midi2.ch0.nrpn900 > midi1.ch1.rpn1 ``` #### Known bugs / problems +Extended parameter numbers (`rpn` and `nrpn` control types) can currently only be transmitted, not properly +received as such. Support for this functionality is planned. + Currently, no Note Off messages are sent (instead, Note On messages with a velocity of 0 are generated, which amount to the same thing according to the spec). This may be implemented as a configuration option at a later time. |
