2.2 INDIRECT MIDI CONTROL

If you want to employ a MIDI form of control when the 1788A’s are connected to R/C units by LAN, direct connection to the 1788A’s MIDI ports cannot be used. This is because only one R/C medium can be accepted by the 1788A at a time: LAN or MIDI. When LAN is selected, the 1788A’s MIDI port is disabled. However, we built MIDI capability into the 1788A-R hardware R/C unit to cover this situation.
