Note On/Off; Program Change Transmission; Program Change Memory; After Touch - Yamaha DX7s Owner's Manual

Note On/Off

This parameter works with MIDI receive only. It's usually set to "all," meaning that all
Note On information received at the DX's MIDI In will play a note. If the Note On/Off
parameter is set to "even," it will only play notes that have even MIDI note numbers.
Similarly, if this parameter is set to "odd," the DX7s will only play notes that have odd
MIDI note numbers. This can be used in conjunction with other MIDI instruments to
produce a variety of interesting effects. Since the Note On/Off parameter works with
MIDI receive only, it won't produce any noticeable effect when you play the DX7s
keyboard.

Program Change Transmission

If the DX7s is connected to another MIDI instrument, various levels of MIDI
communication are possible. The MIDI Program Change Mode determines how the DX7s
will relate to an external MIDI instrument.
Off program changes on the DX7s will have no effect on an external unit
Normal a program change on the DX7s will send the same Program number to the
external unit
Memory the program changes sent will be be those programmed in the Program
Change Memory LCD

Program Change Memory

The Program Change Memory allows you to transmit a different MIDI program change
number for each of the DX7s number buttons. CS 1 selects 1 of the 64 program switches,
and CS 2 selects the program change number that will be sent. The Program Change
Memory only determines which program change number will be transmitted via MIDI
and has no effect on the selection of DX7s memories.

After Touch

You can disable MIDI transmission of After Touch data with this parameter. After Touch
will still affect the DX7s voices normally when this parameter is turned off. The After
Touch parameter is not saved with the System Setup data.
