Dave Smith Instruments Tetra Analog Desktop Synthesizer DSI-1204

The Tetra Analog Desktop Synthesizer Module from Dave Smith Instruments is a desktop synthesizer whose 4 voices can be used in 3 different modes for a variety of performance options.

In Program Mode, Tetra acts as a polyphonic synth with 4 banks of 128 programs.

With Combo Mode, each of its 4 voices can be played in unison or assigned a different program, allowing for four different 16x4 step sequenced patterns simultaneously.

Multi Mode allows you to use each of the Tetra's 4 voices as separate mono parts that can be individually sent out the Tetra's four 1/4" audio outputs.
