Vertigo

Vertigo is an additive synthesizer featuring up to 256 oscillators, Bitmap / Wave (WAV/AIFF/OGG/FLAC) re-synthesis and morphing with very high sound quality and built-in effects.

General:

• Up to 16 voices polyphony.
• Additive synthesizer with audio and bitmap re-synthesis.
• 64-bit Audio Units / VST / VST3 / Standalone.
• Scalable HiDPI Retina GUI.

Envelope:

• 256 breakpoints parabolic envelopes with stage slope control.

Partials:

• Euler generated (Max: -120dB s/noise ratio) (no wavetables used).
• Up to 256 per voice.
• 2 Modulation sources with morphing.
• Phase.
• Amplitude.
• Note pitchshift amount.
• Frequency ratio.
• Frq/amp envelope (see Envelope above).

Synthesis options:

• Harmonize (Harmonic/Odd Harmonic vocoder).
