AS3372E synth voicing chip

Description

The AS3372E is a extended modern version of the venerable CEM3372, as used in Sequential’s flagship Prophet T8 synth and the Oberheim Matrix-12 and Xpander. The original chip contains a two-input voltage-controlled mixer, a 4-pole lowpass filter, and a voltage-controlled amplifier.The Alfa extended version adds a further pair of VCAs organised as a mixing/panning block. As just a couple of examples, this could be be used to increase the input mixer, or to pan the output. It’s basically an entire synth voice on a chip, minus the oscillators and envelopes. It’s a fabulous chip and we’re quite excited to have it here to play with!

Note that since the new chip is extended with extra VCAs, it has more pins than the original (DIP-24 instead of DIP-18) and cannot be used as a drop-in replacement in vintage instruments.
