Twin Stereo Loops Create and stack multi-layered loops with twin stereo tracks — each track being independently controllable with dedicated volume faders and track-select buttons. Creating loops is convenient with the Auto Recording feature, which starts recording the moment you begin playing your guitar, bass, keyboard, or singing, or as soon as you start a connected audio player. Count-In mode gives you one-bar of rhythm before recording starts. You can Undo/Redo as you go. The sky’s the limit, with three hours of recording time! Onboard Effects Fans of BOSS’s world-famous effects will be pleased to find a lineup of creative effects onboard the RC-30. Bend Down provides a dramatic pitch-bend effect. Step Phaser changes phase in incremental steps. Sweep Filter alters frequency in sync with the current tempo. Tempo Delay produces a tempo-synced delay effect. Lo-Fi intentionally degrades the sound to create a distinctive character. Dunk your loops in cool effects without the cost and hassle of adding external gear. Mic Input Vocalists can plug a microphone of their choice directly into the RC-30’s XLR microphone input, complete with phantom power if you wish to use a condenser mic. Sing, overdub, and make multi-layered loops of your voice, create vocal sound-effects patterns, or point the microphone at your acoustic musical instruments, or anything that makes noise and turn it into a cool loop. You don’t have to be a musician to get in on the LoopStation action! Rhythm Guide To keep your loops tight and in time, play along with one of the basic rhythm patterns in the RC-30’s onboard library as you record. Ten types of rhythm types are provided, including Rock, Pop, Funk, Shuffle, R&B, and Latin. A dedicated knob lets you adjust the volume of the rhythm, and you can set the tempo incrementally or via tap tempo. You can also specify the time signature. When you save a phrase, the rhythm type and time signature will also be saved. USB Connectivity You can connect the RC-30 to your computer via a standard USB cable, and back up your RC-30 phrases to your computer for safekeeping. You can also load WAV files from your computer directly into the RC-30. The RC-30 accepts 16-bit/44.1kHz WAV files of up to 1.7GB in size. AUX Input In addition to recording your instrument performances and turning them into playable loops, you can record other external stereo audio sources via the AUX IN. Sound from a digital-audio player or other device connected to the AUX input can easily be recorded and added to your loop.
