Moog Little Phatty
The Little Phatty is a monophonic analog synthesizer manufactured by Moog Music from 2006 to 2013, preceded by the Voyager and succeeded by Voyager Old School. Its design was conceived, in part, by Robert Moog himself, and is the last instrument to have that distinction, although the primary engineer was Cyril Lance. It is also the first Moog product to be produced following his death.

Overview
Overview
Jordan Rudess of the band Dream Theater also assisted with the design of the product. It is one of the few Moog synthesizers to utilize MIDI from the factory (the others being the Minimoog Voyager and the earlier Memorymoog+). This allows for better integration in the modern studio and for live performance. On 9 September 2013, Moog Music announced the discontinuation of the Little Phatty analog synthesizer.

An evening of experimental music and poetry curated by Richard Duckworth of the Department of Music as part of the celebrations of the Berkeley 50. The three nights were centred around the classic Moog System 55 synthesiser.
