The Bit 99 is one of the first synthesizers from which traditional knobs and sliders have been banned. The edit method is easy to understand. The Bit 99 can produce a wide variety of sounds but bass sounds are the best. With a polyphony of three notes, instead of six normally, you can have two sounds layered! Possibilities are almost unlimited and if the 99 patches are not enough you can save the data to tape and load it when you want! This synth was used by 808 State but the synth sounds a lot like Orbital's "In-sides" album. A rackmount version was also released, called the Bit-01.
