Juice3 is an emulation of an old synthesizer built in Reaktor, available for all registered product owners in the NI Reaktor User Library.
The Juice 3 is not in any way a copy of MONARK. The builder did not have access to or ever used MONARK during the making of Juice 3. Instead, the old ensemble Minimood made by NI in 1999, which has then been modified by several users, has been used as the starting point. The basic structure will be recognizable from that early ensemble.
Juice 3 should be seen as a proof of concept; how to emulate the should of vintage synthesizers using the Reaktor environment.
The technology developed for this is called Analog Legacy. Analog Legacy is the theory of modulating all functions in a synthesizer at all frequencies. The key is to find the right balance of the modulation depth for each frequency. Juice 3 is the first attempt to use this theory in practice.
The Minimoog is a monophonic analog synthesizer, invented by Bill Hemsath and Robert Moog. It was released in 1970 by R.A. Moog Inc. (Moog Musicafter 1972), and production was stopped in 1981. It was re-designed by Robert Moog in 2002 and released as Minimoog Voyager.
The Minimoog was designed in response to the use of synthesizers in rock and pop music. Large modular synthesizers were expensive, cumbersome, and delicate, and not ideal for live performance; the Minimoog was designed to include the most important parts of a modular synthesizer in a compact package, without the need for patch cords. It later surpassed this original purpose, however, and became a distinctive and popular instrument in its own right. It remains in demand today, over four decades after its introduction, for its intuitive design and powerful bass and lead sounds.
