Any control change number (CC#00–95) can be
assigned as the B-mode function of a REALTIME CON-
TROLS knob. In this case, the transmitted values will all
be 0–127.
*1 Unlike conventional control changes, pitch bend range,
fine tune, and coarse tune settings are made using RPC
(Registered Parameter Control) messages. In Program,
Combination, and Multi modes, you can use RPC mes-
sages to control the bend range and tuning for each pro-
gram, combination (Combination), or track (Multi). The
procedure is to use an RPN (Registered Parameter Num-
ber) message to select the parameter that you wish to
edit, and then use Data Entry to input a value for that
parameter. To select the parameter, use CC#100 (with a
value of 00–02) and CC#101 (with a value of 00). use
CC#06 and CC#38 to enter the data.
The data entry values for each parameter and the corre-
sponding settings are as follows.

For example, if in Multi mode you wish to set a track
that is receiving channel 1 to a transpose (coarse tuning)
value of –12, you would first transmit [B0, 64, 02]
(64H=CC#100) and [B0, 65, 00] (65H=CC#101) to this
instrument to select the RPN coarse tune. Then you
would set this to –12 by transmitting [B0, 06, 34]
(06H=CC#6), 34H=52 (corresponds to –12), and [B0, 26,
00] (26H=CC#38, 00H=0).
*2 The volume of the X50/microX is determined by sum-
ming the Volume (CC#07) with the Expression (CC#11).
*3 A value of 64 will correspond to the value specified by the
program parameter. 0 will be the minimum, and 127 will
be the maximum. Changing from 63–1 or from 65–126
will adjust the effect from the program parameter setting
toward the minimum value or maximum value. The
internal program parameters listed in (*3, *4) will be con-
trolled.
*4 If the filter type of the corresponding program is Low
Pass Resonance, the filter resonance level will be con-
trolled. If the filter type is Low Pass & High Pass, the
cutoff frequency of the high pass filter will be controlled.
*3, *4

ters of the X50/microX.

In Program mode, when CC#70–79 is received on the
global MIDI channel ("MIDI Channel" GLOBAL 1–1a),
or when a REALTIME CONTROLS [1]–[4] knob is oper-
ated in A-mode or in B-mode when the function is
assigned to CC#70–79, the corresponding program
parameter will be edited temporarily. You can execute
"Write Program" (PROG 0–1) to save that state (except
for some parameters). When you execute "Write Pro-
gram," the values of the corresponding program param-
eters will be rewritten.
In Combination, Multi modes, the program parameters
of the program for the timbre and track of the corre-
sponding MIDI channel will change, but this state can
not be saved directly in the program.
