The V3340 chip is CoolAudio’s modern clone of the famous CEM3340 voltage-controlled oscillator.
It provides Ramp, Pulse/Square, and Triangle outputs,has inputs for oscillator sync, is temperature compensated and stable, and provides excellent 1V/Oct tracking. In short, it’s everything you need from an analog oscillator, on a chip. There hasn’t been a better design than the 3340.
The 3340 is the oscillator chip found in many of the famous polysynths of the analog era; the Sequential Prophet 5 and T8, the Oberheim OB-Xa and OB-8, the Roland Jupiter 6 and MKS-80, and even the MemoryMoog. It also turns up in rarer synths like The Crumar Spirit and the Synton Syrinx.
These are brand new chips from CoolAudio.
