The 50 diverse slice patterns include simple ones like eighth notes, sixteenth notes, triplets, and shuffles, as well as patterns recommended for backing in pop, rock, techno, and more. In addition to these basic slice patterns, the newly developed "harmonic slice pattern" is also included. The harmonic pattern converts the input chords into melodic sequence phrases, creating a percussive groove. Furthermore, the attack knob adjusts the sound's rise time, expanding the sound variations from percussive sounds with a strong attack to slow gear sounds with a smooth rise. The duty knob adjusts the sound duration, allowing adjustment from pulsive sounds to sounds close to the original sound. The combination of the attack and duty knobs creates a wide variety of pattern variations. ■The SL-20 supports 2-in/2-out stereo input/output. You can connect various input sources such as guitars/basses, keyboards, and DJ mixers, and obtain the slicing effect made possible by stereo output. There are six output modes available with stereo output. ■The SL-20 supports the connection of an external expression pedal. You can control parameters such as output level and effect level in real-time, allowing for active tonal changes during performance. Power: 6 AA batteries or AC adapter
