Using MIDI Functions

Selecting a MIDI Channel

You can change the MIDI channel that the REV500 uses to
transmit and receive data. First, press the UTILITY key. If
necessary, press the UTILITY key again until the MIDI
CHANNEL display appears:
MIDI channel setting
Use the REV TIME control to select the desired MIDI
channel. You can set the REV500 to use any of channels 1
through 16, or select OMNI for all channels. You can also
select OFF to disable MIDI communication.
When you have made your setting, press one of the
PROGRAM keys to exit the utility mode.

Using the MIDI OUT Function

This function determines whether MIDI channel messages
received at the MIDI IN terminal will be echoed through to
the MIDI OUT terminal. You should turn this function on
when you want to connect two or more REV500s in a “daisy
chain” so they can be controlled by a single master device
such as a sequencer or keyboard.
Begin by pressing the UTILITY key. If necessary, press the
UTILITY key again until the MIDI OUT display appears:
MIDI message echo setting
Use the REV TIME control to select between the ECHO
BACK ON and ECHO BACK OFF settings. If you choose
ECHO BACK ON, the MIDI channel messages received at
the MIDI IN terminal will be echoed through to the MIDI
OUT terminal. (Other messages received at the MIDI IN
terminal will not be echoed.)
When you have made your setting, press one of the
PROGRAM keys to exit the utility mode.

Editing the MIDI Program Change

Map

The REV500 has a MIDI program change map that assigns
REV500 programs to MIDI program change numbers. This
feature facilitates remote selection of REV500 programs
(which are stored in eight banks numbered 1 through 25)
using MIDI Program Change messages (which can specify
program numbers from 1 through 128).
To edit the MIDI program change map, first press the
UTILITY key. If necessary, press the UTILITY key again
until the MIDI PGM TABLE display appears:
REV500 program selection
MIDI program change
number and cursor
Use the PRE DELAY control to move the cursor to the MIDI
program change number, and the REV TIME control select a
program change number whose program assignment you
want to change. Then move the cursor back to the REV500
program selection, and use the REV control again to select
the program that you want the REV500 to use when it
receives the selected program change number.
Repeat this process to change as many MIDI program
change assignments as you like. When you are done editing
the program change map, press one of the PROGRAM keys
to exit the utility mode.
If you are using a Yamaha FC5 footswitch with the
REV500’s footswitch utility function set to PGM INC/DEC,
depressing the footswitch will select REV500 programs
sequentially in the order specified by this MIDI program
change map.
