Mobius is a free program for the real-time creation and manipulation of audio loops.
Mobius has functionality based on the Echoplex Digital Pro with Loop IV software. It is not a complete emulation, but it does implement many of the Loop IV features, as well as a number of useful new features.
Mobius is essentially 8 synchronized stereo EDP’s, with the ability to copy loops and timing between them. Extensive MIDI and computer keyboard control is available. Audio content may be saved to and loaded from files.
Mobius runs under Windows XP SP2 or Vista. A beta version for Mac OSX 10.4 or higher is also available.
Installers are available on the Download page.
