❍ In Mode (Input Modes)
Standard, X-connect, Merge → A, Merge → B, A only
With the factory settings, MIDI messages received at MIDI IN A are passed to Group
A Parts, and MIDI messages received at MIDI IN B are passed to Group B Parts. In nor-
mal circumstances, there is no need to change the standard setting, but it is also possi-
ble to change the MIDI signal in the following. (diagram on the following page)
Standard
MIDI messages received at MIDI IN A are passed to Group A Parts, and MIDI mes-
sages received at MIDI IN B are passed to Group B Parts. Standard is the factory set-
ting.
X-connect (Cross connect)
This reverses the handling of Standard. MIDI messages received at MIDI IN A are
passed to Group B Parts, and MIDI messages received at MIDI IN B are passed to
Group A Parts.
Merge → A
MIDI messages received at either MIDI IN A or MIDI IN B are sent to Group A Parts.
MIDI messages are not sent to Group B Parts, so they will not sound. For example, you
might use this setting when you wish to play Group A Parts simultaneously from a MIDI
keyboard and from a MIDI sequencer.
Merge → B
This reverses the handling of Merge → A. MIDI messages received at either MIDI IN
A or MIDI IN B are sent to Group B Parts. MIDI messages are not sent to Group A Parts,
so they will not sound.
A only
When using the Roland Super MPU (MIDI Processing Unit: two MIDI OUTs), some
software will transmit the same data to both of this unit's MIDI IN connectors. This will
cause two Parts to sound in unison, causing an unnatural effect. In such a case, do not
use both MIDI INs. Either disconnect one of the MIDI cables, or use the preceding pro-
cedure to set to A only. When A only, data received at MIDI IN B will be ignored.
* Be aware that if the computer switch on the rear panel of this unit is set to either PC-1, PC-2 or
Mac, MIDI data received at MIDI IN A will not be sent to the Parts (the sound generator), but will
be sent through the computer connector to the computer (p.123).
* The data sent from the computer through the computer connector will be treated as received
from MIDI IN A, and will be passed to the various Parts according to the Input Modes setting.
❍ Rx Sys. Mode (System Mode Set Receive Switch): On/Off
The selection of Single Module Mode or Double Module Mode (p.116) is called the
System Mode. The Rx Sys. Mode setting is the receive switch for MIDI messages
(System Mode Set p.194) that select the System Mode. If Rx Sys Mode is turned Off,
the mode will not change even if System Mode Set messages are received. If Rx Sys
Mode is turned On, the mode will change.
