Roland already showed with the AIRA series that Roland stands for modern synths, which incorporated Roland's innovative ACB technology (Analog Circuit Behavior). This technique has been acclaimed for its authentic reconstruction of the sound and behavior of historical analog synthesizers. The Roland SYSTEM-8 Plug-Out Synthesizer features a highly advanced ACB chip, driving 8-voice polyphony, three oscillators, high-resolution filters and multipurpose LFOs. This spacious sound engine produces everything from classic analog pad sounds, basses and lead synths to fresh, dynamic sounds and space-filling structures coveted by modern sound designers. Sound production is easy, thanks to the intuitive control panel with many, many knobs and controls. You can add filters and effects in an instant, including side-band filter, overdrive, fuzz, delay, chorus, reverb.
