About the Guide

The RC-50’s built-in guide provides a rhythmic backing for you to play with while you’re recording and playing phrases. The guide offers many different patterns in various time signatures and musical styles, with high- quality audio using sampled drum and percussion sounds.

In addition to providing a timing reference, the guide also incorporates a feature called Loop Quantize. It helps keep phrases in sync with the guide by automatically trimming or extending the phrase length when a phrase is closed.

Loop Quantize is also available with the guide off in some circumstances. We’ll cover Loop Quantize in detail in the second half of the booklet.

Using the GUIDE LEVEL Knob

To turn the guide on, simply turn the front panel GUIDE LEVEL knob clockwise. As indicated by its label, this knob also functions as a level control for the guide sound. The guide is on when it’s set to any level from 2-200.

When the GUIDE LEVEL knob is turned, the current setting—OFF, 2-200—is briefly displayed.

To turn the guide off, turn the GUIDE LEVEL knob fully counter-clockwise.

Starting and Stopping the Guide Sound

When the GUIDE LEVEL knob is set to 2 or higher, the guide sound becomes audible when recording, overdubbing, or playback of a phrase is begun.

The guide sound is silenced when phrase playback is stopped (the current phrase in Single mode or all phrases in Multi mode).

The guide sound can also be turned on and off manually by pressing the GUIDE START/STOP button. This can be done any time before or during phrase recording, overdubbing, or playback. The button’s indicator lights when the guide sound is audible.

The START/STOP button doesn’t turn the guide itself on or off; it only starts and stops the audible guide sound. If you want to disable the guide entirely, turn the GUIDE LEVEL knob to the OFF position.

GUIDE START/STOP can also be controlled with the TEMPO or UNDO/ REDO pedal, an optional FS-5U or FS-6 foot switch, or MIDI CC #80. See Pages 70-72 in the RC-50 Owner’s Manual for information about assigning functions to pedals. See Pages 77-78 for information about MIDI CC functions.

Setting the Tempo

The guide follows the current patch tempo setting. The patch tempo can be set anywhere from 40 to 250 beats per minute—or “BPM”—with a resolution as fine as one-tenth of a BPM.

� From the Play screen, press TAP TEMPO to display the current patch tempo.

The Play screen is the RC-50’s “home” screen—it’s the screen displayed after the RC-50 finishes its power-up sequence. You can always return to the Play screen from any other screen by pressing EXIT. To learn more, see the RC-50 Workshop booklet Patches.
