discoDSP is a software instrument company founded in 2002 by George Reales and based in Albuquerque, New Mexico. The company develops virtual synthesizers, samplers, and effects as AU, AAX, VST, VST3, LV2, and iOS plug-ins for macOS, Windows, Linux, iPad, and iPhone. Over the years, discoDSP has collaborated with notable DSP developers and sound designers including John Argüelles (Arguru), George Yohng, Lucio Asnaghi, and Oskari Tammelin.

discoDSP is best known for Discovery and Discovery Pro, virtual analog synthesizers inspired by the Clavia Nord Lead 2 that can import Nord Lead 2 and Nord Lead 2X Sysex patches directly. The lineup also includes OB-Xd, a free Oberheim-inspired synthesizer; OPL, an emulation of the Yamaha OPL2 FM chip; Corona, a virtual analog and wave synthesizer featuring Roland JP-8080 SuperSaw unison; and Vertigo, an additive wave re-synthesizer. On the sampling side, Bliss is a performance sampler supporting WAV, SF2, and SFZ formats.

The company's Retromulator plug-in takes a different approach, providing multi-core low-level emulation of classic hardware synthesizers and samplers. discoDSP also offers soundware preset packs and utility plug-ins such as MidiKeys and KeyPad, rounding out a catalog that spans virtual analog, FM, additive, and sample-based synthesis.

discoDSP has 6 products cataloged on Equipboard, including Synth Plugins, Sampler Plugins, and Compressor Plugins. Their gear is featured by 4 artists, with the strongest followings in Electronic and Rock. Notable users include Disclosure, Sean Tyas, and Sakuraburst.
