Mr. Alias Pro 2.4

Mr. Alias Pro

Mr. Alias Pro is a fully professional software synthesizer which exploits the properties of digital audio to achieve extremely bad sounds. It is an essential instrument for the digital purist, building on Mr. Alias 2 and adding some professional features.

Mr. Alias Pro is available as a VST plugin for Windows, Mac OS X, and Linux, and as an Audio Unit for Mac OS X.

Exclusive features in Mr. Alias Pro include:

  • Better-sounding "Pro" GUI with realistic wood sides
  • Skinnable
  • Auto Randomizer
  • Integrated MIDI keyboard - play with mouse or QWERTY keys (right-click to hold a note)
  • Modulation of internal parameters from audio input, envelopes, oscillators, etc
  • Extra assignable envelope and two LFOs
  • Glide and Retrigger for legato playing in Mono mode
  • Set each oscillator to a constant pitch, ignoring MIDI note value
  • 2 more banks of patches
  • Drawable waveforms (also load/save wav files)
  • And much more! (not really)

Everything from Mr. Alias 2 is also included:

  • 2 oscillators
  • 18 waveforms
  • Full stereo processing
  • 6 filter types including a formant filter
  • Filter envelope
  • External audio processing (no need to hire Butch Vig)
  • Patch randomizer button
  • Highly configurable MIDI control with MIDI learn
  • MIDI-controllable patch morphing
  • "Amateur" bank of 128 presets
  • Drag & drop preset and MIDI map loading

Complete information can be found in the User's Manual.


Each download includes Mr. Alias Pro, the user's manual, three banks of patches, some extra waveforms, and three skins. Mr. Alias Pro operates in Demo mode until it is registered with a license key.

Demo limitations:
1. An box annoyingly bounces around the GUI. It links to this page if you click on it.
2. On Tuesdays, parameters change themselves at random while the GUI is showing.
