Support for this functionality is planned. +Extended parameter numbers (EPNs, the `rpn` and `nrpn` control types) will also generate events on the controls (CC 101 through +98, 38 and 6) that are used as the lower layer transport. When using EPNs, mapping those controls is probably not useful. + +EPN control types support only the full 14-bit transfer encoding, not the shorter variant transmitting only the 7 +high-order bits. This may be changed if there is sufficient interest in the functionality. To access MIDI data, the user running MIDIMonster needs read & write access to the ALSA sequencer. This can usually be done by adding this user to the `audio` system group. |
