discoDSP OB-XD v2.4 x64 VST VST3 AU WiN MAC LiNUX [FREE]

discoDSP OB-Xd is a free virtual analog synthesizer inspired by the Oberheim OB-X, aimed at producers who want vintage-style synth sounds with practical software controls. Rather than following the hardware design exactly, it combines OB-X-inspired behavior with expanded sound-shaping options. Subtle randomized detuning helps create the rich, slightly unsettled character associated with classic analog synthesis.

Its continuously variable multimode filter provides additional tonal flexibility, while MIDI CC support and MIDI learn let you assign parameters to a controller. OB-Xd has no built-in effects, so you can choose your own chorus, delay or reverb plugins to shape the finished sound.

Version 2.4 adds a preset browser bar that can be hidden from the menu, plus drag-and-drop loading for FXP presets and FXB banks. It also improves MIDI learning, saves custom controller mappings for use across instances, and addresses preset synchronization issues. Theme support and HiDPI-ready graphics offer options for customizing the interface.

For hobby producers working in Windows-based FL Studio or Ableton Live setups, OB-Xd offers an approachable route into analog-style synthesis without a purchase requirement.
