Quad, Voltage Controlled 24db Cascade OTA Filter with Lowpass and Bandpass Outputs

In stock

SKU: tone Categories: ,


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. The filter design uses Cascade OTA topology.

Tone can be used to immediately add 4 individual filters to any system, whilst also functioning as a perfect match for Qu-bit CHORD, or any other modules offering multiple/ polyphonic outputs (Synthesis Technology E370, Studio Electronics QUADNIC etc..)
