KarmaFX is a company that offers high quality, virtual instrument & effect plugins VST/AU for PC and Mac. We aim to produce inexpensive and easy-to-use audio plugins that meet the demands of professional musicians as well as hobbyists. All KarmaFX VST plugins work in VST compatible host applications on PC/Windows. KarmaFX Synth Modular 2 is also available as Audio Unit and VST for Mac/OS X.

Development of our award-winning modular synthesizer, KarmaFX Synth Modular, started as a hobby project back in 1998. At that time it wasn't just a synth, but a standalone application for music-making. It included a sequencer, a tracker, an effect rack, and - of course - a software synthesizer. It was used to produce tracks as early as 1999.

KarmaFX Synth Modular was later converted into a VST. A public beta was released in 2005, and version 1.0 for Windows was released as shareware in 2007. Up until then KarmaFX focused on creating small, easy-to-use VST effect plugins for music production, known as the KarmaFX Plugin Pack. These popular plugins were, and still are, provided as donationware. KarmaFX Synth Modular was ported to Mac in 2010. An introductory video is available here. KarmaFX Synth Modular 2, containing many new modules, features and improvements, was released in 2020. Announcement video is here. VST3 and Apple Silicon support was added in 2024.

KarmaFX Synth Modular has won Computer Music's Value Award in 2009 and The Technofile Awards Silver Price for Best Modular Soft Synth in 2016. KarmaFX was founded in 1998 by Kasper Nielsen, and is located in Copenhagen, Denmark. For more information, please contact KarmaFX at info@karmafx.net.
