If you have trouble seeing the player, and for downloads, go here
Synth Info:
Mr. Alias by Insert Piz Here (now only available on plugins4free) uses non-bandlimited oscillators which can be transposed near to and beyond the Nyquist frequency, causing most of their spectra to be aliased back into audible non-harmonic frequencies.
The sound can then be further processed by a number of crude "effects."
Various: Presets
