The Alesis Andromeda A6 is a 16-voice, 16-channel multitimbral analog synthesizer by Alesis which was released in 2000 and discontinued[1] in 2010. The Andromeda has analog oscillators and filters combined with modern digital control. It can be considered a hybrid of older and newer technologies, but its entire signal path is purely analogue. The VCOs have a very practical autotune function. A feature missing on other old polysynts. The VCOs have FM and ring modulation and suboscillators. These features makes it possible to create a much wider sonic palette than usual on analog polys.
