INTRODUCTION
Dave Smith who co-developed the DSI -120 integrated circuit that was used in the famous Prophet 08 in 2007 and the Mopho in 2008, amongst other achievements is also credited with the design of the award-winning small but powerful Tetra. The Tetra which has four DSI –120 circuits, provides us with an analog four-note polyphonic, four-part multitimbral programmable synth at a very affordable price.
The Tetra has a Polychain output so you could chain it to a Prophet 08 to make it 12 voice, or to Mopho to make a five-voice synth or of course to another Tetra to provide eight voices.
