Elektrostudio is a Polish software instrument developer run by Robert Krzywicki, producing a catalog of freeware VST plugins for Windows that emulate classic analog synthesizers, string machines, drum machines, and tape keyboards of the 1970s and 1980s. The project is distributed through the Softsynth Portal and has been widely mirrored on freeware directories such as KVR Audio and Plugins 4 Free.

The lineup focuses on faithful recreations of vintage and often obscure instruments. Releases include ODsay (inspired by the ARP Odyssey), Six Moon June / Sixth Month June (Roland Juno-6), Micromoon (Moog Micromoog), Moon Sono SX (Moog Sonic Six), OR2v (Oberheim Two Voice), DavoSynth (Davolisint), eSLine (ARP/Eminent Solina string ensemble), Tapeotronic (Mellotron-style tape keyboard with flute, strings, and choir), Rhythmus (vintage rhythm box), and Ocet. Many of these plugins are bundled together in the Analog Pack collection.

Elektrostudio's instruments are characterized by small install footprints, simple GUIs modeled on the original hardware panels, and a focus on esoteric or hard-to-find gear rather than the most commonly cloned synths. They are frequently cited in online communities such as KVR Audio and Gearspace as go-to freeware options for producers seeking analog-style timbres without dedicated hardware.

Elektrostudio has 3 products cataloged on Equipboard, including Melodic Techno, Drum and Bass - General, and Pop - General.
