Vertigo is an additive synthesizer, able to import WAV and bitmap files
into two morphable layers, each with up to 256 oscillators.


Features:


General

Up to 16 voices polyphony.


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).
