The ARP 2500 is a monophonic analog modular synthesizer. It was the first product of ARP Instruments, Inc., built from 1970 to 1981.

It is equipped with a set of sliding matrix switches above each module; these switches are the primary method of interconnecting modules.

Features

There are rows of 1/8" miniphone jacks at the end of each row of matrix switches, [1] to interconnect rows of switches. The main 2500 cabinet can hold 15 modules, and optional wing cabinets can each hold 8. The matrix switch interconnection scheme allow any module's output to connect to any other module's input. Unlike the patch cords of competitive units from Moog and Buchla, which can obscure control knobs and associated markings, the matrix implementation enables a cable-free experience but at the price of greater cross-talk. [2]

Although the 2500 proved to be a reliable and user-friendly machine, it was not commercially successful, selling approximately 100 units. [3] A collection of the 2500's most popular modules was packaged into a single, non-modular unit as the ARP 2600, leaving out the matrix switching and more esoteric functions.

Notable users and appearances

John Kongos first used one at Trident Studios in 1971, then in 1973 he acquired his own - it was used extensively at his Tapestry Studio, on his own recordings as well as Def Leppard (Pyromania), Mutt Lange, Alain Chamfort, Tony Visconti, Ryan Ulyate and many others.

In 1972 Pete Townshend of the Who used an ARP 2500 on the Who's Quadrophenia . [4] Townshend built his own home studio to experiment and record, due to the enormous amount of time he spent creating his groundbreaking synthesizer orchestrations on both Quadrophenia, and the movie version of Tommy.

The ARP 2500 was extensively used by British producer David Hentschel on recordings such as "Funeral for a Friend" from Elton John's 1973 album Goodbye Yellow Brick Road . Jeff Wayne's 1978 multi-platinum selling album War of the Worlds features the ARP 2500, including the sound of Martian speech.

In the 1977 motion picture Close Encounters of the Third Kind , [5] a 2500 unit is used to communicate with aliens. Phil Dodds, ARP's Vice President of Engineering, was on set to install and manage the synthesizer; Steven Spielberg, liking his looks, cast him on the spot as an extra to play the 2500. The unit featured in the film consisted of a fully loaded main unit, two fully loaded wing cabinets and dual keyboards in a custom case.

It has been used by artists such as Aphex Twin, David Bowie, Vince Clarke, Ekseption, Faust, John Frusciante, Jean Michel Jarre, Cevin Key, [6] Kraftwerk, Jimmy Page, Vangelis and the Who. The composer Éliane Radigue has worked almost exclusively with the 2500.

A software synthesizer or softsynth is a computer program that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths may be readily interfaced with other music software such as music sequencers typically in the context of a digital audio workstation. Softsynths are usually less expensive and can be more portable than dedicated hardware.

Modular synthesizers are synthesizers composed of separate modules for different functions. The modules can be connected together by the user to create a patch. The outputs from the modules may include audio signals, analog control voltages, or digital signals for logic or timing conditions. Typical modules are voltage-controlled oscillators, voltage-controlled filters, voltage-controlled amplifiers and envelope generators.

<span class="mw-page-title-main">Synthesizer</span> Electronic musical instrument

A synthesizer is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments and may be synchronized to other equipment via MIDI.
