Synthesis horizon expander.

The Oberheim® Synthesizer Expander Module was a complete and gigantic sounding analog synth voice in a box. Now, SEM V resurrects this beautifully minimalist machine in stunning vintage detail, adding capabilities that meet the needs of today’s music makers.

A thing of analog beauty

Originally meant as a companion module to sequencers and other synths, the SEM sported a multi-mode filter and two tremendous oscillators that made it unlike anything else. Combining multiple SEMs into 2, 4, and 8-voice systems took things to another level - just ask Rush or Herbie Hancock. SEM V puts all this power, and more, right in your DAW.

Sounds Analog

True Analog Emulation® technology brings all the fat and warmth in a way no sampled version can. You’ll hear the difference and so will your audience.

Team Player

From synthpop to hip-hop, almost every musical style can use some of the burbling bombast of the SEM.

Vault of Voices

Set polyphony up to 32 voices for massive brass, swelling strings, and ponderous pads.

That Filter

The 12dB/octave multimode filter that sounded unlike anything else, eventually shaping the identity of Oberheim®, exquisitely recreated.
