3340 VCO Submodule

3340 VCO Submodule


The Electrosmith 3340 VCO is an analog oscillator submodule that uses a reissue of the legendary CEM3340 IC. This chip was responsible for some of the most iconic synth sounds in history including the SH-101, Jupiter 6, Prophet 5, OB-8, and Memorymoog. The typical application circuit from the datasheet has been implemented on this submodule, along with the most well known tweaks and improvements from over the years. Whether you’re looking to evaluate the 3340 sound, or build a 16 voice poly synth, this submodule provides an off the shelf solution for classic analog goodness.
