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. 16
