Vertigo Additive Synthesizer

Additive Synthesis Without Limits

Vertigo is an advanced additive synthesizer built around 512 Euler generated oscillators per voice with a pristine noise floor of -120 dB. Using Fourier based synthesis and FFT resynthesis, it reconstructs audio and image material into fully editable partial structures for everything from classic harmonic tones to abstract spectral textures.

Morph between dual A/B parameter states, shape every partial with detailed breakpoint envelopes, and sculpt sound through dual filters, spectral editing, formant processing, and eight dedicated effects. With scalable HiDPI graphics, drag and drop workflow, and support for up to 16 voices, Vertigo combines deep synthesis control with modern performance and responsiveness.
