Sampleson is a virtual instrument developer that builds VST, AU, and AAX plugins for music producers and composers. The company calls itself a "virtual luthier," emphasizing playability and a small CPU and disk footprint over the massive multi-gigabyte sample libraries common to the genre, and pairs traditional sampling with proprietary modeling techniques to keep its instruments lightweight.

The catalog spans acoustic and electric pianos, organs, synths, and percussion. Notable titles include Metapiano, a modeled grand piano; Suit73, Reed200, and Reed106, which emulate classic electric pianos; Markus 88 and Model T, takes on vintage electromechanical keys; the tonewheel organ Collab3; the melodica Melox; and a line of generative and creative tools such as Things, Tactile, Scaper, Skywaves, and Predictor. Drum and percussion offerings include Drumbada, Brushify Pro, Boomcha, and Haptic.

The brand operates under Nextart Technology LLC and sells primarily direct through its website, with distribution through retailers like Plugin Boutique, Loot Audio, Best Service, and Thomann.

Sampleson has 32 products cataloged on Equipboard, including Virtual Instrument, Instrument Bundles, and Drum Machine. Most Sampleson products sit on the budget-friendly end of the spectrum.
