RC-500: How to use MIDI to change Rhythm Variation?
MIDI can be used to control multiple parameters. MIDI can be used to control the Rhythm Guide Variation switch to change the beat of the rhythm guide between Variation A and Variation B.
In some cases MIDI CC (control commands) in some 3rd party midi controllers will only allow a single value to be sent per CC#. BOSS MIDI works best when implementing MMC (momentary MIDI control), to counter this, simply recreate the same CC# twice, one will have a value of 0 and the other will have a value of 127 (or vice versa 127/0 for OFF status).
RC-500: RHYTHM VARIATION VIA MIDI
RC-500 has an Assignment menu to create special functions for the onboard controls, as well as external controller commands. Here are the basic steps to creating an Assignment on the RC-500:
- Press the MEMORY button, and turn the MEMORY/VALUE knob clockwise, until ASSIGN1 is displayed.
- Push ENTER, and turn on ASSIGN1.
- Turn the MEMORY/VALUE knob to SOURCE, and push ENTER.
- Turn the MEMORY/VALUE knob until CC# is displayed.
(These CC#'s you'll need to remember, as you're going to use these numbers for your external master MIDI Controller to sync the function together). - Push ENTER, turn the MEMORY/VALUE knob, change SRC MODE to TOGGLE, push ENTER
- Turn the MEMORY/VALUE knob to TARGET, push ENTER.
- Turn the MEMORY/VALUE knob to select the control you wish to engage or disengage.
For example: Turn MEMORY/VALUE till VARIATION appears. - To save this setting to the MEMORY location slot, press WRITE: EXIT+ENTER together, and then ENTER twice more to confirm and WRITE/save the custom settings.
The MIDI CC# that you've designated as the control ASSIGNMENT SOURCE for VARIATION, will have to be the matching CC# on your external master MIDI Controller for TX/TRANSMIT CC# to change the Rhythm Variation parameter A to B.
Please make sure that both MIDI devices are communicating on the same set MIDI TX/RX CHANNEL (MIDI TRANSMIT/RECEIVE CHANNEL).
Typically, BOSS devices are default to MIDI CHANNEL: 1.
Users should always check the MIDI Channel of both devices or all MIDI devices in the MIDI event chain.
