auction details:
"Muse Research Standard Receptor Rack Synthesizer Plug-In Module
1.0 Revision C. 1GB RAM. 150GB hard drive. With Ivory and Elektrik Piano installed
General Description
One instrument... Two rack spaces... Millions of sounds... Infinite possibilities.

That's the Muse Research Receptor - a unique and versatile musical instrument that takes the best software-based synthesizers and effects processors available, and turns them into real instruments. With the push of a button, Receptor can transform itself from a sampler into a guitar processor; from a drum module into a synthesizer; or from a delicate mastering tool into a screaming drawbar organ.
Plugin software has completely changed the way we make music. Puny samples crammed into tiny chips are a thing of the past. Fixed architecture synths, by their very nature, are forever incapable of adapting to an ever-shifting sonic landscape. In today's musical world, virtual instruments reign supreme. But using plugin software can be an exasperating experience. Stability concerns and high latencies limit their effectiveness on stage, and high CPU demands limit their flexibility in the studio.
Receptor solves these problems by combining everything that's good about plugins with everything that's good about hardware."
