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.
