MIDI Parameters
Rx Channel
Use this parameter to assign a MIDI transmit channel to the “Basic”
channel.
Parameter Value
Rx Channel 1–16
User Program PC Rx
This parameter is used to enable or disable the reception of program
change and bank select messages related to User Program selection.
Parameter Value
UPG PC Rx O, On
Master Volume Rx
Allows you to enable or disable the reception of Master Volume
messages that would change the E-A7’s overall volume. This is an
exclusive message common to all newer MIDI devices.
Parameter Value
Master Volume
Rx
O, On
Part Switch Rx
Whenever you mute or un-mute a part on the “Style Parts” page,
the E-A7 transmits an NRPN message that describes your action. You
can keep the E-A7 from responding to such messages to avoid that
external instruments mute its parts.
Parameter Value
Part Switch Rx O, On
Style
The following parameters are located on the display page that can
be selected using [MENU]

“Style.”
The Style channel is used for receiving program change and bank
select messages that select styles and volume messages that change
the style’s volume.
The MIDI address of a style consists of three elements: a CC00
number, a CC32 number and a program change number. The values
assigned to CC00 and CC32 dene the style (see the separate
booklet), whereas the program change number denes the Division
(Intro, Ending, etc.).
Sending only a program change number selects another Division of
the currently active style. Be aware, however, that only sending CC00
and CC32 messages (without a program change) has no eect.
NOTE
When you select another style on your E-A7, it transmits a CC00–
CC32–PC cluster on the Style channel, which you could record
using an external sequencer.
Tx
Switches the transmission of MIDI messages on the Style channel on
or o.
Parameter Value
Tx O, On

NTA
The following parameters are located on the display page that can
be selected using [MENU]

0
“NTA.”
NTA notes are only received (from an external MIDI instrument).
What you play in the chord recognition area of the keyboard to feed
the Arranger is automatically converted to the corresponding MIDI
note numbers, so that all style parts transmit their notes to external
instruments. There is thus no need to transmit the note messages of
what you play in the chord recognition area (NTA) separately.
These parameters allow you to specify on which MIDI channels the
E-A7 should receive chord information used to change the style’s key
in real-time.
