Triple Stereo Loops

Expanded PedalboardWith the RC-300’s three stereo tracks, you can create, stack, and manipulate multi-layered loops, each track being controllable independently. The “Auto Recording” feature starts recording the moment you begin playing your instrument, or as soon as a connected audio player starts playing. Count-In setting gives you one-bar of rhythm before recording starts. You can Undo/Redo as you go. Along with three hours of recording time available, anything is possible!
The RC-300’s ultra-wide pedalboard features an Expression pedal, which can be assigned to a range of parameters with enlarged footswitches for controlling REC/PLAY and STOP for each track. You also get a master ALL START/STOP footswitch too. Along with three independent faders, providing instant control of each track’s output volume. And for even more control, you can also connect external Expression pedals and footswitches.

A dedicated LOOP FX footswitch is available for direct activation of the onboard effects. Edit the effects parameters in real time with the Expression pedal for hands-free creativity onstage. You can set the effects to any single track along with to the entire mix, taking your creativity and musical expression to the next level.
To keep your loops tight and in time, you can play along with some of the fun rhythm patterns from the RC-300’s built-in library as you record; the Loop Quantize feature helps you keep your looped recordings in time. Tons of rhythm types are available, including rock, pop, shuffle, Latin, and more.
