Actually most knobs are dedicated to patch editing. It has a welcome new feature, a modern vocoder! There are also 8 control knobs for setting various mixer-type settings (level, pan, fx send). That's right, it has effects on board! It's got a great sound too! Choose from basic categories like 'bass sounds', 'dirty bass', 'pad sounds', 808 & 909 kits and much more! There's plenty of memory (96 user patches) to store your own creations. The filter and envelopes are flexible and sound very good.
Also taken from the Rave-O-Lution is the incredible pattern-based seven track sequencer with part mutes and tap-tempo! A truly useful dance music production synth capable for demanding studio use and creative live performance control with excellent sounds and a funky new vocoder! An ideal all in-one-synth for any DJ or dance musician! It has been used by KMFDM/MDFMK founder Sascha Konietzko.
