    Vital – Free VST Synth by Vital Audio

    ☆ Rating: 5.0/5 (KVR Audio)

    Vital is a Spectral Warping Wavetable Synth developed by Matt Tytel. Matt Tytel had previously developed Helm, which is a very successful and famous free synth VST. Vital features Spectral Oscillator Warping which acts on waveform’s harmonics. This results in sounds of different shapes and timbres from one source. Vital also features pitch-splice or vocode wavetable converter* which can generate wavetables from text.

    One thing anyone would most like in Vital is the ability to visualize every modulation. Vital renders modulation animations at 60FPS which is handled by GPU.

    Vital gives you ability to modulate almost every parameter using custom LFO shapes, envelopes and randomized sources by drag and drop features similar to Serum. The envelopes are quite snappy. Finally, it gives you the ability of Stereo Modulation which can be triggered by any LFO shape, envelope of randomized sources. This will help you create out of the world stereo experience for your synthesized sound. Because of all these, Vital becomes super efficient and robust to synthesize any kind of sound.


    • Wavetable oscillators with both frequency warping and wave warping
    • Custom Sample source
    • Unison Efficiency
    • Stereo-splitable LFOs with custom shapes and shape editing
    • Keytracking on LFO settings
    • Modulation on envelopes with custom curves
    • Modulation remapping: customize the shape of every modulation
    • Multiple random modulation sources
    • MPE Support
    • Built in Oscilloscope and Spectrum viewer
    • 8 routable Effects including multiband compressor, multi-mode phaser and 16 voice chorus.

    Vital has 4 (Free & Paid) versions available through their website: Vital.Audio. The free (Basic) version comes with full functionality and 75 presets and 25 wavetables. *only limitation is the pitch-splice or vocode wavetable converter feature is limited in free version
