Dave Smith Instruments Tetra Desktop Synthesizer

No longer available at zZounds
Dave Smith fit four Mopho synths into one compact box to create the Tetra -- a 4-part, 8-oscillator analog polysynth complete with a Curtis low-pass filter.

The Dave Smith Instruments Tetra takes the award-winning sound and features of Mopho, multiplies them by four, and packs them in a box less than half an inch larger!

Tetra has multiple personalities. It is a four-voice, analog poly synth, sort of a "mini Prophet." It's a four-part, multitimbral synth with separate outputs, essentially four Mophos in one very compact box, and it's a voice expander for other Tetras or the Prophet '08.
