Space-conscious lowpass filter and volume processor.
A combination of VCF + VCA + Mixer that lets you mix three different sound sources, and shape their tone, and levels in a breeze.
The Pony Filter is built around the SSI2144 FATKEYS™ Chip. Has the elegant sound of the classic transistor filter without the associated distortions, due to Dave Rossum’s “improved ladder” topology.
