reFX has released another update for their softsynth Vanguard. After version 1.5. released only a few months ago, they have released version 1.5.1. VANGUARD combines the good old analog synthesizer idea with the latest technology. All analog devices of classic synthesizers are emulated by high-quality DSP (digital signal processing) functions. reFX spent a lot of time programming the synthesis functions, and the result is a warm and rich sounding synthesizer plugin with all the benefits of todays digital technology.
