Electrosmith 3340 VCO & 2144 LPF

Synthesist John L Rice shared this hands-on demo of the Electrosmith 3340 VCO & 2144 LPF.

Both modules are available in both MU and Eurorack formats.

The Electrosmith 3340 VCO is an all-analog, voltage controlled waveform generator that uses a reissue of the legendary Curtis CEM3340 IC. Some consider this chip to be the greatest sounding analog oscillator of all time.

Simultaneous outputs of sine, triangle, sawtooth, and square waves are available. Temperature compensation circuitry provides precision volt per octave tracking over 10+ octaves across all temperatures and a configurable soft/hard sync input allows time reversal or hard reset of phase for each waveform.

The Electrosmith 2144 LPF is a classic analog filter with a 24dB per octave slope in the MU modular synthesizer format.

It features a reissue of the renowned SSM-2044 IC that formed the filter section for countless vintage synths. The filter’s tone is warm and creamy at low resonance settings and moves into fat, over-driven squelches at the higher end of its range.
