Viper

Viper

Viper aims to deliver the sound characteristics of legendary hardware synthesizers in a virtual format. We can call Viper a Virtual Performance synth, with a vast array of features like: multiple oscillator types with user waveforms, Sync, Frequency Modulation, Ring Modulation, unison up to 8 voices, filter saturation, filter routings, mod matrix, high quality effects, a powerful arpeggiator, and much more!

A lot of time and research has been invested to make the sound engine of Viper capable of delivering a wide array of sounds, everything from smooth, lush pads, huge basses, and powerful leads, typically associated with traditional analog synthesizers. This was achieved with careful coding, experimenting, analysing hardware synths, and using the ear to fine tune the controls. A constant randomization is also active in the synth to slightly alter its sound to mimic electronic components.

The engine is written in optimised code to use as little CPU consumption as possible, while maintaining a high quality sound engine, finding a good balance between the two. The synth automatically turns off any parts that are not used to further reduce CPU usage. Viper also has a smoothing algorithm for its controls to remove the ‘steppyness’ when it goes between values to give that extra polished sound.

    I bought Viper today, but when I change presets while playing a project in Ableton, it crashes now and then… Very frustrating. Especially because I like the sound of the synth…

      Unfortunately the way the licenses work for the product, does not make it possible to transfer them.

    Hi adam,

    I tried the 64 bit version of Viper Demo V1.0.5 and noticed that reverbs and delays are not faded out when changing presets. Does it have to be that way?

      Its only happening in the demo version, the full version does not do that. Hopefully I will fix the demo in the next version.

    Hi Adam.
    Any chances for non FlowStone ported version? Like PHAZOR.
    I’m waiting so long for mac version…

      No chance. Phazor was a small plugin that was easily ported by one person, Viper is a huge project it would take someone many months to port it.

    If I were to purchase this can I use it on two systems or only just one? Trying to figure out if I’m buying it twice or not.

      You can use it on multiple computers but they have to be yours.
