Freeware - Circular Labs Mobius Looper VST Plugins

http://www.circularlabs.com/

Mobius is software for the real-time creation of audio loops. It was inspired by the venerable hardware loopers of the past, but moves beyond them in many powerful and exciting ways. You can think of Mobius as 8 synchronized stereo loopers that can be used in any combination with extensive MIDI and computer keyboard control. Loops may be saved to and loaded from files. A powerful scripting language allows you to create macros or customize Mobius to support your unique style of performance. Mobius is available for both Windows (XP and Vista) and OS X (10.4 or higher).
