Groove and Melody Maker
The SL-20 transforms your music into percussive “chopped” grooves. Fifty rhythmic patterns are onboard, with adjustable note attack and duration, plus amazing Harmonic Slice effects. Create high-energy patterns onstage in real-time, or use the SL-20 as a songwriting and recording tool. Play the sliced sounds in realtime while capturing them with Loop Record.
Flexible Control
An internal tap-tempo feature is included, as well as the ability to sync to external MIDI clock. Sound characteristics of the SL-20 such as attack, duration, effect level, and direct level can be controlled by the onboard knobs or from an external Expression pedal.
Universal FX
The SL-20 is an addictive effect that inspires creativity. It’s great for guitarists, but it’s equally useful for other instrumentalists as well. Plug in a bass, keyboard, iPod®, or any other instrument or music-playback device. DJs and dance-music artists will also love the SL-20 as a rhythmic-performance tool.
