Chapter 6
Disconnecting the Keyboard 
from the Internal Sound Source 
(Local OFF)
The XP-30 contains a controller section (keyboard section) 
and sound generating section, packaged as a single unit. This 
means that you can make a setting (Local Control) that 
specifies whether or not the performance data from the 
keyboard will be transmitted directly to the sound source.
When you use the XP-30 by itself, you will normally set it to 
Local ON. However, when you are using it as a sound 
generator for a DTM (desktop music) system, you should set 
the Local parameter (SYSTEM/MIDI/PERFORM MIDI) to 
OFF so that the keyboard will be disconnected from the 
internal sound generator.

Turn on the Thru Function of Your 
Sequencer Software
In order for the musical data received by the computer from 
the XP-30 to be transmitted back to the XP-30, the 
Thru 
function
 of the sequencing program must be turned on. 
When the Thru function of the sequencing program is turned 
on, MIDI messages received at MIDI IN will be re-
transmitted without change from MIDI OUT.
For details on whether or not your sequencing program has a 
Thru function, and how to set the Thru function, refer to the 
owner’s manual for your sequencing program.
* If your sequencing program does not have a Thru function, set 
the XP-30’s Local Control to ON.
* For some sequencing programs, System Exclusive messages are 
not transmitted by the Thru function. If you are using such 
software and wish to record System Exclusive messages, turn 
the XP-30’s Local Control setting ON.
While at this setting, 
the XP-30’s keyboard 
and controllers are 
disconnected from 
the sound generating 
section, so they will not 
directly  control it. 
All performance data 
that arrives at MIDI IN 
will be output from 
MIDI OUT.
