System Setup; Transmit Channel; Receive Channel; Omni Mode - Yamaha DX7s Owner's Manual

System Setup

Since the use of many basic MIDI functions might depend on the contents of a specific set
of Voice & Performance data, the DX7s provides a special memory location, System Setup
Memory, to store basic MIDI parameters and orher data in conjunction with a Voice &
Peformance Memory block. This System Setup Memory contains settings for the
following parameters:

Transmit Channel

This parameter allows you to set the DX's MIDI transmit channel. If you turn this
parameter off, no MIDI data will be sent.

Receive Channel

You set the DX's MIDI receive channel with this parameter. If you turn this parameter off,
all incoming MIDI data will be ignored.

Omni Mode

When Omni mode is on, the DX7s will receive MIDI data from all of the 16 MIDI
channels (the MIDI receive channel is disregarded).

Local On/Off

If Local is set to off, notes played on the DX7s keyboard will not engage the DX's
internal sound mechanism. Turning Local off has no effect on the transmitted MIDI data.

MIDI IN Control Number

This parameter sets the MIDI controller number for the MIDI Controller (MC) functions
programmed with each voice. The function of this controller is set via button 26 (see page
51).

CS 1 and CS 2 Controller Numbers

The CS 1 and CS 2 Controller Number parameters have two functions:
1. To set the controller numbers that will be transmitted by
CS 1 and CS 2 via the MIDI out. This is useful for controlling external MIDI
instruments.
2. To set the controller numbers that will control the voice parameters assigned to CS
1 and CS 2 in the Performance data. This is useful for changing voice parameters
from an external MIDI device.
