When these messages are received, the same editing opera-
tion will be performed as on the transmitted device.
After MIDI exclusive data has been received and processed,
a Data Load Completed message will be transmitted. The
control master device must not transmit the next message
until this message is received (or until a sufficient interval of
time has elapsed).
When you change programs, combinations or multi set, or
use parameter changes to edit, the changes will affect the
data in the edit buffer and will not be stored in internal
memory unless you Write, so that the changes will be lost if
you re-select the program, combination or multi set. The
Write operation can be performed by a MIDI exclusive Pro-
gram Write Request or Combination Write Request message,
in addition to the usual method of using this instrument’s
switches. (

If notes are “stuck”
If for some reason, notes become “stuck” and will not stop
sounding, you can usually stop the sound by changing the
mode. If notes played via MIDI are stuck, you can discon-
nect the MIDI cable.
MIDI transmits a message called Active Sensing [FE] at reg-
ular intervals. A device that receives this message will be
aware that an external MIDI device is transmitting to it. Sub-
sequently, if no MIDI messages are received for a certain
interval of time, the receiving device will decide that the
connection has been broken, and will turn off any notes that
had been sounded via MIDI and reset its controller values.
Playing the X50/microX multi-timbrally
from an external device
The X50/microX can be connected to an external device and
played multi-timbrally in the following ways.
• MIDI messages from the external device can play a
combination (8-part multi-timbral performance). You
can change the overall settings (programs, levels, and
effects) by using program change messages to switch
combinations.
• MIDI messages from the external device can be used to
play a multi set (16-part multi-timbral performance).
Overall settings (programs, levels, effects etc.) can be
changed by using a Song Select message to switch multi
sets.
If you’re using Multi mode as a 16-channel multi-timbral
sound module, you will normally set “Multi Mode”
(GLOBAL 0–2a) to Ext-Seq.
Synchronizing the playback of the
arpeggiator
The choice of whether the X50/microX will be the master
(the controlling device) or the slave (the controlled device) is
made by “MIDI Clock” (GLOBAL 1–1a).
Using this instrument as master and the
computer as slave
Connect the MIDI OUT connector of the X50/microX to the
MIDI IN connector of your external MIDI device (
☞OG
p.32). Alternatively, connect the USB connector of the X50/
microX to the USB connector of your computer.
• When you set “MIDI Clock” to Internal, this instrument
will be the master device, and will transmit MIDI timing
clock messages.
The tempo can be controlled from this instrument. Simul-
taneously, the performance of the arpeggiator will be
transmitted via MIDI. (In Combination, Multi modes,
data will be transmitted by timbres/tracks whose “Sta-
tus” is BTH, EXT, or EX2.) An external tone generator
connected to the MIDI OUT will sound, and the tempo of
an external sequencer can be controlled.
Using the computer as master and this
instrument as slave
Connect the MIDI IN connector of the X50/microX to the
MIDI OUT connector of your external MIDI device (
☞OG
p.32). Alternatively, connect the USB connector of the X50/
microX to the USB connector of your computer.
• When you set “MIDI Clock” to Ext-MIDI, Ext-USB, or
Auto the X50/microX will be the slave device.
The tempo will follow the MIDI timing clock. If you play-
back the external sequencer, the X50/microX’s arpeggia-
tor will synchronize to the external timing clock. (
☞OG
p.105)
Even if “MIDI Clock” is Ext-MIDI, Ext-USB, or Auto and
the X50/microX is being controlled from the external
device, the performance of the arpeggiator performance
will still be transmitted via MIDI. (In Combination and
Multi modes, the arpeggiator performance will be trans-
mitted from timbres/tracks whose “Status” is BTH, EXT,
or EX2.)
Recording the MIDI output of this instru-
ment’s controllers, arpeggiator, and
internal sequencer to an external
sequencer/computer
If you wish to record the MIDI output of the X50/microX’s
controllers, arpeggiator, and internal sequencer on an exter-
nal sequencer or computer and use the X50/microX as the
monitoring and playback tone generator while you record,
you must turn off the X50/microX’s Local Control setting
(“Local Control On” GLOBAL 1–1a), and set your external
sequencer/computer for echo-back (a function by which the
data received at the MIDI IN is retransmitted without
change from the MIDI OUT) so that the data from the X50/
microX’s controllers, arpeggiator and internal sequencer
will not be applied in duplicate to the tone generator.
Using the REALTIME CONTROLS [1]–[4]
knobs to record MIDI control changes on an
external MIDI sequencer/computer
Set the X50/microX to Local Control Off. Set the external
MIDI sequencer/computer to Echo Back On. With these set-
tings, recording and playback will occur correctly, and the
control changes will not be applied to the tone generator in
duplicate.
Recording the arpeggiator on an external
MIDI sequencer/computer
When the arpeggiator is on, playing the keyboard or operat-
ing the controllers of the X50/microX will operate and con-
trol the arpeggiator. The arpeggiator will operate and be
controlled in the same way in response to MIDI messages
received at the MIDI IN. The MIDI messages generated from
the arpeggiator will be transmitted from the MIDI OUT
according to the Local Control setting (“Local Control On”
GLOBAL 1–1a) as described below.
