Key Features:
* Scrolling Voice-Print, frequency and note based.
* Stereo 'Scope and Spectrums
* Combinations of above.
Dissatisfaction with the limited options with the built-in scrolling voice-print combined with boredom and a general experimental nature created and developed these .avs presets.
The two features missing in the built-in voice-print were 1) Scrolling voiceprint with a spectrum, and a log-based (musical note based) spectrum (how we hear) rather than the frequency based.
... but probably done before and done better. The vp is nice in a way, but most people will find it boring, and the rest of the "main" preset is all too simple and boring. As a pack it just doesn't work.
