Quad Filter

Tone is a quad, voltage controlled filter with low pass and band pass outputs. Its four channel architecture enables the intuitive patching of shimmering, polyphonic textures.

The 24dB slope provides a warm, buttery character. Self oscillation allows each channel to double as a sine wave oscillator with v/oct tracking across four octaves. Cascade OTA topology. A perfect match for the Chord.
