Free Virtual Analog Synthesizer Plugin by BlauKraut Engineering

Charlatan Screenshot

Charlatan is a polyphonic, subtractive virtual analog (VA) synthesizer plugin with focus on sound quality and easy usability. It comes with a flexible, yet not overwhelming feature set which encourages artists to start tweaking instead of just relying on presets. Inspite of it's simplicity, Charlatan's architecture is flexible enough to create both classic sounds and rather experimental noises. While making no compromise about sound quality, the sound engine has been highly optimized for efficient CPU usage making Charlatan well suited as a "bread and butter" synth even in projects with a large number of plugin instances.

Best of all, it's FREEWARE! Enjoy!

(*) Due to some tweaks to the sound engine, there may be subtle audible differences when loading some of the old patches. In most cases, it should be possible to compensate for those with some fine adjustments. Still, I recommend to keep an old 1.x version of Charlatan around if you need to fully preserve old projects. Sorry for the inconvenience...
