PMF 3320 VCF Randy Piscione
"Demo of the PM Foundations 3320 VCF. This one is based on the CEM3320 VCF chip, which was used in the Prophet 5. It's capable of some very organic sounds, make sure you listen to the entire video. Get it here: http://www.tindie.com/products/pmfoun..."
"Randy Piscione says: 'There are lots of bits that are squelchy, and almost organic-sounding, much like some of the sounds Joe Zawinul would get out of an ARP 2600. Everyone should have one of these.'
SUMMARY
Use this PCB and front panel to build your own FOUR-POLE VOLTAGE CONTROLLED FILTER using the classic CEM3320 filter chip from Curtis Electromusic Specialties or the new AS3320 from Alfa. The CEM3320/AS3320 is a self contained voltage-controlled four-pole filter with voltage-controllable resonance. It has an exponential (V/Oct) frequency control input which can cover more than ten octaves. The filter chip is temperature compensated.
The CEM 3320 was used in classic synths such as the Sequential Prophet 5.
IMPORTANT NOTE
This is a PCB and Panel set only. One high quality PCB and one front panel ONLY are included. You will need to purchase your own components and build your own module. Comprehensive build instructions and BOMs are provided to help you source the components needed and we even provide links to shopping carts to simplify sourcing those components. Some product photos above show COMPLETED build.
