REQ: Adam Szabo Viper v1.2.2

Viper aims to deliver the sound characteristics of legendary hardware synthesizers in a virtual format. It comes with multitude of features like: multiple Oscillator types, Sync, Frequency Modulation, Ring Modulation, Unison up to 8 voices, Filter Saturation, Filter Routings, Modulation Matrix, high quality Effects, a powerful Arpeggiator, and much more!
A lot of time and research has been invested to make Viper capable of delivering a wide array of sounds, everything from lush pads, huge basses, and powerful leads, typically found in analog synthesizers. This was achieved with careful coding, experimenting, analyzing hardware synths, and using the ear to fine tune its parameters.
The audio engine is written in optimized code to use as little CPU consumption as possible, while maintaining a high quality sound engine, finding a good balance between the two. Viper also has a smoothing algorithm for its controls to remove the ‘steppyness’ associated with digital synthesizers.
Viper is available as a 32 and 64-bit VST 2.4 and VST 3 instrument for Windows.
