With a design optimized for the 21st century, the Synthesizer Expander Module combines vintage technology with digital innovations, allowing you to create deep basses, vibrant leads, and unique percussion with ease. Plus, its multi-mode filter programmed by award-winning synthesizer designer Mark Barton (MRB) makes it a must-have tool for any music producer.
What is the Synthesizer Expander Module?
The Synth Expander is a free emulation of the standalone Oberheim® module, originally designed as an add-on to the DS-2 digital sequencer. This plugin faithfully recreates the 12 dB/oct state-variable filter, renowned for its flexibility and analog warmth. With low-pass, band-pass, high-pass, and notch modes, this filter remains the star of the show, delivering a rich and detailed sound.
Thanks to a collaboration with Mark Barton (MRB), the plugin includes a unique “Phasor” effects section, emulating the classic Oberheim pedal, as well as a high-quality, tempo-synced echo effect. It’s perfect for both beginners and professionals looking to experiment with authentic vintage sounds.

It also offers a professional echo effect with tempo sync and full MIDI control to automate all parameters from your DAW.
