System Setup; Channel Messages; Note On/Off; Program Change Transmission - Yamaha DX7 II FD Authorized Product 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 new DX provides a special memory location, System
Setup Memory, to store basic MIDI parameters and other data in conjunction with a Voice
& Performance Memory block. This System Setup Memory contains settings for the
following parameters:

Channel Messages

This LCD display allows you to set the DX's MIDI transmission channel, MIDI receive
channels (for Voice A and Voice B in Performance Mode), and MIDI Omni Mode
reception (on or off— if on, the receive channel settings are inactive).

Note On/Off

This parameter is usually set to off, meaning that all keys played produce a note. Other
settings (Odd, Even) can be used in conjunction with other MIDI instruments to produce a
variety of interesting effects.

Program Change Transmission

If the new DX is connected to another MIDI instrument, various levels of MIDI
communication are possible. The MIDI Program Change Mode determines how the DX
will relate to an external MIDI instrument: If Mode is set to Off, program changes on the
DX will have no effect on the external unit; if Mode is set to Normal, a program change
on the DX will send the same Program number to the external unit; if Mode is set to
Programmable, the program changes sent will be be those programmed in the Program
Change Trans LCD display.

Local On/Off

This parameter allows you to turn the DX's internal synthesizer on and off (as part of a
MIDI system). If Local is set to Off, notes played on the DX keyboard will not engage the
DX's internal sound mechanism.
