Insert Piz Here has released Mr. Alias 2, a freeware instrument plug-in for Windows, Mac and Linux:

Mr. Alias 2 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.”

Though it is based on the same concept as the original, Mr. Alias 2 is completely rewritten for cross-platform compatibility, and has a number of significant improvements.

Mr. Alias 2 is available as a VST plugin for Windows (32-bit), Mac OS X (Universal Binary), and Linux (x86), and as an Audio Unit for Mac OS X.
