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.

Key features:
● Classic Oscillators with user waveforms
● Multisaw (up to 9x Sawtooth waveform)
● Sub Oscillator
● Noise with coloring
● Punch
● Osc Sync, FM, RM
● Unison up to 8 voices
● 2 Zero Delay Feedback filters with Low Pass, High Pass, Band Pass, Band Reject (notch)

● 4 Filter routings: Serial 4, Serial 6, Parallel, Split
● 4 Envelopes: Filter Env, Amp Env, Mod 3 and Mod 4
● 3 LFOs with Oscillator shape morphing
● Mod Matrix
● FX:
● Character (analog boost)
● Distortion
● Filter effects: Ring Modulator, Frequency Shifter, Vowel Filter, Comb Filter
● Phaser
● Chorus
● Delay
● Reverb
● Equalizer
● Arpeggiator with user patterns and Midi Out
● Built in Preset browser
● Section locking
● Midi learn
● Resizable GUI

    The new resizeable 1.04 is great to use. Great Pleasure. Thanks for the labour.

    I’m trying to download the update per the instructions recently mailed out but I’m not having any luck.

    Hi Adam, what are you planning in the next patch?

    • Adam Szabo

      It should be a bigger update so it will take time, but one feature will be to load own skins 😉

    Any chances “komplete” integration with Komplete Kontrol? I know I can use it by open instrument and manually assign controls, but It would be nice to have it in search results too.

    I know I will repeat what hundreds have said already, but it is GREAT synth!!! Very user friendly! I couldn’t understand how all these oscilators filters, envelopes work until VIPER. GREAT GREAT INTERFACE and even greater SOUND!!!

    Privet Adam ) Is there any information on the next patch, other than the possibility of changing skins ? And is it possible to make a selectable anti-aliasing x8, x16, etc. Sorry for my googlish )

      I have to rewrite the entire GUI for the user skins to work and it will be big work, so I cannot promise anything else at the moment. Oversampling is already built in the synth and optimized.

    Can you make it available for a renting option just like serum?

      Its technically not possible at the moment

    Downloaded demo, tried it in Bitwig Studio 2.4 64bit, Windows 10 64 bit. 64-bit version of Viper produces some unwanted random clicks during playback, and always clicks when I switch between tabs. Is it a known bug?
    32-bit version works seamlessly. I don’t know exactly about the future of 32-bit plugins support in my DAW, so the bugfix is very much expected.

      I haven’t noticed this, I will take a look

        clicks on tab change began to appear after adding automation

        • Adam Szabo

          It seems for some reason changing tabs uses too much CPU. For now, either increase your audio buffer, or lower the Viper Gui size to not get clicks and pops, or close the Viper gui.

            32 bit version has no such issue..

      I have noticed the clicks when I move the mouse over the Arpegiator view while I play a note. I’m using Viper 1.04 64 Bit and Fl Studio 20.

        Yes the arp is redrawn when the mouse is over it. Hopefully I can find a fix, in the mean time dont move your mouse over the arp while playing, or lower the gui size to stop the clicking.
