Support for this functionality is planned. +MIDI 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. While JACK has rudimentary capabilities for transporting OSC messages, configuring and parsing such channels with this backend would take a great amount of dedicated syntax & code.
