MIDI Communication Via REAC

In addition to audio communication, the REAC connection allows for MIDI communication as well.
Both the S-4000S and S-4000H units feature MIDI IN and OUT jacks. When you connect MIDI devices
to these jacks, they can send and receive MIDI information to and from each other via REAC. For this
application, you can think of the REAC connection as a "MIDI cable extender."
REAC's ability to pass along MIDI information can prove useful for synchronizing devices via MIDI
Time Code (MTC), triggering MIDI sound modules and samplers, and integrating MIDI remote control
devices.
Notes on REAC MIDI Communication
• MIDI data received at the MIDI IN connector of the Master REAC device is transmitted unchanged
to the MIDI OUT connectors of the Slave REAC device and any SPLIT REAC devices.
• MIDI data received at the MIDI IN connector of the Slave REAC device is transmitted unchanged
to the MIDI OUT connector of the Master REAC device.
• When an S-4000S or S-4000H is set as a Split REAC device, its MIDI IN connector is disabled.
• A Split REAC device can only receive MIDI data from a Master REAC device (MIDI data reception
from a Slave REAC device is not possible).
