the entire OASYS. You can also transmit MIDI System

Basic
MIDI Channel (Global MIDI Channel) [1…16]
Sets the global MIDI channel.
The global MIDI channel is used in the following cases.
• When transmitting and receiving performance data 
in Program mode (Program P0: Play) and Sampling 
mode.
• When selecting combinations via MIDI in 
Combination mode (Combination P0: Play).
• When controlling timbres or effects that have been 
set to Gch in various modes
• When transmitting and receiving system exclusive 
messages
MIDI received
In Program mode (P0: Play), MIDI data is received on 
the global MIDI channel, but in Combination mode 
(P0: Play) or Sequencer mode, MIDI data is received on 
the MIDI channel specified for each timbre or track.
In Combination mode (P0: Play), program changes 
received on the global MIDI channel will switch the 
combination (1–1c: MIDI Filter).
Use the global MIDI channel to switch IFX 1–12 
(CC#92), MFX1&2 (CC#94) and TFX1&2 (CC#95) 
on/off.
To control the pan following IFX, sends 1/2, MFX 1/2 
and TFX1/2, use the global MIDI channel when in the 
Program or Sampling mode; while in the Combination, 
or Sequencer modes, use the channel specified 
separately by Ctrl Ch for IFX1–12, MFX1&2, TFX1&2, 
and MEQ. By setting Ctrl Ch to Gch, you can control 
these parameters from the global MIDI channel.
MIDI output when playing OASYS
In Program mode and Sampling mode, this data will 
be transmitted on the global MIDI channel. In 
Combination mode, data will be transmitted 
simultaneously on the global MIDI channel and on the 
MIDI channels of timbres whose Status (Combination 
0–1b, 2–1a) is set to EXT or EX2.
In Sequencer mode, musical data will be transmitted 
on the channel specified for the currently selected track 
(Sequencer 0–1a) (whose Status is BTH, EXT, or EX2).
External mode
In each mode when the control surface CONTROL 
ASSIGN EXTERNAL switch is on, you can use the 
mixer sliders 1–8, master slider, knobs 1–8, and 
switches 1–16 to control a connected computer or MIDI 
device.
