discoDSP has released version 2.0 of OB-Xd, a freely downloadable virtual synthesizer (with optional $49 donation) for digital audio workstations on Windows, macOS, and Linux.
OB-Xd emulates the Oberheim OB-X, OB-Xa, and OB-8 analog synthesizers. It isn’t meant to be a 100% accurate recreation of the original instruments, but rather a close approximation in a digital format with some intentional differences and improvements.See also: Surge FREE Synthesizer Plugin Gets An EPIC Update
The virtual instrument was first released as freeware back in 2014 by 2DaT. Two years later, discoDSP continued the development of the instrument, keeping it free and introducing an optional $49 donation for users who would like to show their support. discoDSP implemented several improvements, including iOS support, alternate skins, and more.
The OB-Xd is based on the Oberheim OB-X. It attempts to recreate its sound and behaviors, but as the original was very limited in some important ways a number of things were added or altered to the original design.
The latest 2.0 edition of OB-Xd introduces compatibility with Linux and macOS Catalina, MIDI CC support, a faster GUI, updated JUCE framework, XML based skinning, and a new dark theme designed by Ilkka Rosma. The instrument can now also work in standalone mode. Some of the presets have also been updated so that they are fully compatible with the new 2.0 version.
OB-Xd is listed in our recently updated list of the best free synthesizer VST plugins. It is one of the best analog-inspired virtual synthesizers around, along with the excellent PG-8X plugin by Martin Lüders.
Everyone interested can download OB-Xd from the discoDSP website; no registration required. You can optionally donate $49 to support the developer. The instrument is available in VST plugin format for compatible hosts on Windows, macOS, and Linux. Both 32-bit and 64-bit plugin hosts are supported.
