PX Add-On 8: The Classic D

The The Classic D is a three-oscillator monophonic synthesizer manufactured originally in the early 1970s, before being brought back in more recent years for a limited run. The Classic D not only helped shape decades of music production, but still defines and inspires instrument design and technology to this very day. 

As the popularity of massive walls of modular systems began to dwindle, The Classic D was the answer. It established the possibility of having an advanced yet portable synthesizer. It was not only the original to offer such a range of features and functions, but it was the first in its class as a retail-ready commercial instrument. This led to unparallel popularity at the time, with fans and users such as Parliament, Stevie Wonder, Keith Emerson, Gary Numan, Tangerine Dream, Kraftwerk, and Herbie Hancock to name just a few. 

The Classic D Add-On was captured using a pristinely maintained, original-run hardware unit. Direct from the synth archives of Dave Smith himself, The Classic D had been uniquely modified. We recorded each take through a purely analog signal path until the very final stages to ensure all the character, tone, and warmth were retained, resulting in every note being faithful to the original.
