Brainworx’s bx_oberhausen is an homage to Oberheim

Up to 32 voices at your fingertips.

Brainworx Audio bx_oberhausen

Brainworx Audio has made its first foray into virtual instruments with the bx_oberhausen synth, modelled after Tom Oberheim’s Synthesizer Expander Module (SEM).

This new plug-in features all-analogue modelling with full polyphony of up to 32 voices, superseding what its forbear could deliver. The voices can be combined in a Unison mode, which can be used with Brainworx’s Tolerance Modelling Technology (TMT) for complex, analogue-like sounds, as the brand claims.

TMT, which also features in the brand’s SSL 4000 plug-ins, aims to “accurately replicate individual component variations specified by the manufacturer”, according to Brainworx Audio.

Elsewhere, the bx_oberhausen features Mid/Side (M/S) processing, letting you determine which sound part passes through the filter section. The result is a variety of processing modes spanning bass-loaded foundations to off-kilter stereo options.

As a final touch, Brainworx Audio has also included effect plug-ins like Mäag Audio’s Air Band EQ, offering you more sound-sculpting options on the bx_oberhausen.

Here’s a snapshot of the synth’s other features:

  • Two oscillators, each offering saw and pulse waves
  • Frequency modulation for the oscillators
  • An Arp (arpeggiator) with adjustable Swing parameter
  • Modulation matrix with more sound design possibilities
  • More than 300 presets created by professionals
  • Fully NKS (Native Kontrol Standard) compliant
