E-MU Xboard Control
Xboard 51
NRPN Mode
For devices that support NRPNs (Non-Registered Parameter
Numbers). NRPN messages can span across two controller
numbers (LSB and MSB), increasing the range of potential values.
A complete NRPN message consists of NRPN parameters LSB and
MSB (set in the Xboard Control) and NRPN data LSB and MSB
(sent by the Continuous Controller).
NOTE: NRPN mode does not have an Initial Controller setting.
Keyboard Settings
Basic MIDI Channel:
The keyboard always transmits on the basic MIDI channel. The controller knobs,
wheels and footpedal/footswitch also transmit on the Basic MIDI channel, except
when the “MIDI Channel Number Per Control” option is selected.
MIDI Channel Number Per Control
Normally, the keyboard and all controllers are transmitted on the Basic MIDI
channel. This option allows you to select any MIDI channel for each knob, the two
wheels and the footpedal. The example below shows how you might control four
parameters on four different synthesizers using the sixteen controller knobs.
L This value (0-127) defines NRPN parameter LSB (Least Significant Byte).
M This value (0-127) defines NRPN parameter MSB (Most Significant Byte).
The keyboard ALWAYS transmits on
this MIDI channel. The knobs also
transmit on this channel, except
when “MIDI Channel” Number Per
Control” is selected.
