The Rhythm Guide output can be assigned globally in the RC-50. Having this flexibility lets you send the signal of the guide to the Main or Sub (or both) Outputs. For example, if you wanted the Guide to come out of the SUB outputs only, you would choose "SUB" for the assignment.
Here's how.
1. Press SYSTEM/USB.
2. Press PARAMETER right repeatedly to select "Sys:Guide Out."
3. Turn the PATCH/VALUE knob to choose the desired setting (MAIN, SUB, MAIN + SUB).
4. Press EXIT when you're finished. The new setting is stored automatically.
