Designed in 1980 by Chris Huggett of OSCar fame, this is a seriously quirky synth with a huge sound for it's size. It may look like it'd be difficult to play, but it's not, and it's a lot of fun too. You can create a wealth of unusual sounds, from deep basses to soaring leads, modulated textures to drones and other sonic madness. The filter alone is worth buying it for - i've never heard a synth with such a razor sharp sweep when you open the filter up."
