Keeping track of the success of his first synthesizer and willing to create a new product, Tom Oberheim simply combined two SEM modules with a keyboard and a basic sequencer putting them into one housing. This made it possible to get a duophonic synthesizer with wide possibilities.

The mini sequencer has two independent outputs for controlling two voice modules. 16 controllers set voltages per step, while the active step is illuminated by the LED. The number of steps can be set from one to eight with a rotary switch. The tempo of the sequencer is set by the rotary switch. The module enables sample&hold.

The keyboard has 37 non-dynamic keys, the transpose switch allowing you to change the tune of the instrument within three octaves.

There is also a portamento adjust control and a pitch bend.

The output module has a mixer for voice modules, master volume, master output and headphone output.
