OB-Xd
OB-Xd is a software synthesizer for macOS that recreates the Oberheim OB-X sound and adds modern polyphonic, MIDI, and performance controls.
What is OB-Xd?
OB-Xd is a virtual analog software synthesizer for macOS that helps musicians, producers, and sound designers create classic OB-X-style pads, basses, leads, and layered textures. It is developed by DiscoDSP LLC and is available as a standalone application as well as plug-in formats commonly used in DAWs. The instrument preserves the character of the original Oberheim-inspired design while expanding it with modern workflow features such as deep unison voicing, MPE support, and bi-directional MIDI control. OB-Xd is useful for electronic production, retro synth sounds, film scoring, and live performance setups that need expressive keyboard control. It also supports Apple Silicon and Intel Macs, making it suitable for current macOS music production systems.
Key features
- Play an Oberheim-inspired virtual analog synthesizer for pads, basses, leads, and classic poly sounds.
- Use polyphonic unison to stack multiple voices per note for thicker chords and mono leads.
- Perform with MPE controllers using per-note pitch, timbre, and pressure expression.
- Route MIDI output from the standalone app to external gear or other music apps.
- Load and use the standalone app or run it inside compatible DAWs as an Audio Unit, VST, or VST3 plug-in.
- Import older OB-Xd presets and community patches for continued sound library use.

Safety overview
Status: Mostly safe
OB-Xd is a legitimate music production app and plug-in from DiscoDSP LLC. Its MIDI features and audio plug-in behavior are consistent with a synthesizer, and a one-time internet connection may be used for license activation. If you did not intentionally install it, check whether it was added by a DAW bundle, plug-in collection, or another user account on the Mac before removing related files.
Recommendation: Keep OB-Xd if you use music software, a DAW, or external MIDI gear and want this synthesizer available in your workflow. If you do not make music or no longer use the instrument, you can remove it along with its support files to free space and reduce plug-in clutter in compatible audio apps.
