Six oscillators/synths constructed from sampled irreglar sine, triangle, square and sawtooth waves from 40s and 50s valve/tube oscillators which can can be mixed, modulated and mangled with a multimode filter, envelopes and a multi-wave LFO. There's also a vintage noise generator in there as a seventh oscillator.
However, the thing's alive - click on the central cog and that rusty old thing will trundle into action, do a complete revolution and generate a new sound at random for you that harks back to early pioneering electronica enhanced by a comprehensive multi-FX chain...
Whatever genre of music you work in, there's a place for Cognosphere for adding texture and substance. Although Cognosphere will do pads, basses, sub-basses and leads, etc., it is most at home in obscure abstract textures with randomly generated sounds you'd never come up with yourself and the valve oscillators lend an air of genuine retro authenticity.
