bx_oberhausen
bx_oberhausen is a virtual synthesizer plugin for Avid Pro Tools (AAX format) from Brainworx Audio, distributed through Plugin Alliance. It is a full analog-modeled synthesizer based on a classic analog synthesizer expander module, featuring up to 32-voice polyphony, Tolerance Modeling Technology (TMT) to replicate component variations of analog circuits, M/S stereo processing, frequency modulation, an arpeggiator, and an integrated effect section. It ships with over 300 presets and is available as part of Plugin Alliance's CORE and PRO subscriptions.
AI Recommendation
1 suggestionbx_oberhausen is available as a native Apple Silicon build — Brainworx added native AAX support in version 1.6.0 (August 2023) and has continued improving the plugin through the latest version 1.7.0 (January 2026). Since Pro Tools itself requires a native Apple Silicon build on M-series Macs (Pro Tools 2023.6 or newer), your copy of the plugin is almost certainly running natively if you are on a current Pro Tools installation. To ensure you have the latest native build, use the Plugin Alliance Installation Manager (the vendor's official plugin manager) to check for and install updates — this is the correct update channel for all Plugin Alliance AAX plugins. Simply open the Installation Manager, search for bx_oberhausen, and install any pending updates. If you are a CORE or PRO subscriber, the plugin is included in your subscription; if you own a perpetual license, you may need to authenticate via iLok.
