Editing Analog synthesizer (section)

===1980s–present===
During the middle to late 1980s, [[digital synthesizer]]s and [[Sampler (musical instrument)|samplers]] largely replaced analog synthesizers. By the early 1990s, however, musicians from the [[techno]], rave and [[DJ]] scenes who wanted to produce electronic music but lacked the budget for large digital systems created a market for the then cheap second hand analog equipment. This increased demand for analog synthesizers towards the mid-1990s, as larger numbers of musicians gradually rediscovered the analog qualities. As a result, sounds associated with analog synths became popular again.

Over time, this increased demand for used units (such as the 1980 [[Roland TR-808]] drum machine and [[Roland TB-303]] bass synthesizer). Late 1970s-era drum machines used [[tuned resonance]] voice circuits for pitched drum sounds and shaped [[white noise]] for others. The TR-808 improves on these designs, by using detuned [[Square wave (waveform)|square wave]] oscillators (for the cow bell and cymbal sounds) and analogue [[reverberation]] (for the handclap sound). The demand for the analog synth sound led to development of a variety of [[analog modeling synthesizers]]—which emulate analog [[Voltage-controlled oscillator|VCOs]] and [[Voltage-controlled filter|VCFs]] using samples, software, or specialized digital circuitry, and the construction of new analog keyboard synths such as the [[Alesis Andromeda]], [[Prophet '08]], and Moog's [[Little Phatty]], as well as semi-modular and  modular units.

More recently, the resurgence has been supported by analog modeling synthesizers, new analog hardware from companies like Moog, Korg, and Behringer, and the booming Eurorack modular format, which reintroduced the appeal of customizable modular synthesis to a new generation of users.
