slight but distinct stepping of the filter, especially when more pronounced resonance is used. However, there are several workarounds: The first is to press the control knobs while rotating them to access smoother increments. The second method involves the use of a MIDI controller or synthesizer, whose controllers generate higher resolution data values. The AN1x responds to this due to its mature MIDI implementation and NRPN recognition. The result being a smoothing out of the filter sweep, therefore giving a more authentic analog feel. Physical characteristics The keyboard's main housing is made of ABS plastic, and the chassis base is metal. Dimensions: (W) × (D) × (H). Weight: . Reception and usage Though containing more features than its contemporaries, the control interface of the AN1x initially proved frustrating for some users, due to its programming being matrix-based rather than one control per parameter like the Roland JP-8000. To counter these early misgivings, a sound set was released by Yamaha UK, called the London sound set, which contained clones of some of the JP-8000 presets. This helped to demonstrate the sound capabilities of the AN1x. In 2000, Yamaha used the AN1x synthesis architecture to produce the PLG150-AN plugin board for the CS6x. The following year, Yamaha followed the AN1x with the AN200, a groovebox-type desktop sound module. The AN1x has been used by numerous artists, including: Jean Michel Jarre, Psyclon Nine, History Of Guns, Velvet Acid Christ, Nine Inch Nails, Nitin Sawhney, Phish, Igor Khoroshev of YES, Steve Hillier of Dubstar, Jacob Thiele of The Faint, 808 State, Antti Pouta of Pariisin Kevät, Above & Beyond, Jesper Anderberg of The Sounds, and Daniel Ruppar of Down In The Lab/One Chord Till Anarchy, Boards of Canada.
