LinPlug Virtual Instruments, founded by Peter Linsener in Berlin, Germany, is a software synthesizer developer that built a reputation for innovative and sonically distinctive virtual instruments. Linsener began developing plugins in the early 2000s, when the virtual instrument market was still in its infancy, and LinPlug grew into one of the respected independent names in the space. The company's name derives from its founder's surname.

LinPlug's catalog spans a wide range of synthesis approaches. Albino, a collaboration with Dutch sound designer Rob Papen, became one of their most celebrated products — a versatile polyphonic synthesizer known for its rich sound and deep modulation capabilities. Other notable instruments include Spectral, a unique additive synthesizer with four 121-band filters and 256-harmonic oscillators; SaxLab, a dedicated saxophone emulation; the RMV drum machine, which combined analog-style percussion synthesis with sample playback; CrX4, a sample-based synthesizer with multiple generator types; MorphoX, a morphing synthesizer; and Octopus, a feature-rich synth developed with Maxx Claster. LinPlug also offered the free Alpha synthesizer, a 32-voice polyphonic subtractive synth that served as an accessible entry point to their ecosystem, along with Organ 3 (a drawbar organ simulation), relectro (an effects plugin), and Element P (a percussion synthesizer).

LinPlug has 12 products cataloged on Equipboard, including Synth Plugins and Virtual Instrument. Their gear is featured by 12 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Justice, Mike Oldfield, and Orbital.
