Synthesizer Expander Module Bundle

The Synthesizer Expander Modules are emulations of the classic Oberheim® Synthesizer Expander Module, aka the "SEM." Originally released in 1974, the keyboardless, mono SEM module was intended as a companion to the Oberheim DS-2, one of the earliest digital sequencers.

The Voltage Modular Synthesizer Expander Modules are similar to the "patch panel" SEM reissues released in the 2000's - exactly like the original 70s versions, with the addition of an extensive patch panel for modular flexibility. Featuring a circuit-correct recreation of the SEM’s 12 db/oct state-variable filter, programmed by award-winning synth designer Mark Barton (MRB), the Synthesizer Expander Modules sound incredible! The Synthesizer Expander Module Bundle includes mono and poly versions of this classic instrument.
