Qu-16 MIDI Protocol V1.2 4 CD 29/11/2013 iss.1

NRPN Parameter control

Qu mixer parameters are transmitted and received as MIDI NRPN (Non-Registered Parameter

Number) messages. The MSB (most significant byte) selects the mixer channel (CH), and the

LSB (least significant byte) selects the parameter number (ID). The data entry MSB sets the

parameter value (VA) and LSB sets the index value for its range (VX) where needed.
