Tone is comprised of four voltage-controlled filters, each with separate audio inputs, cv control, and individual bandpass and lowpass outputs. Since each filter uses OTA topology, users can rest assured that their tones will be as warm and buttery as possible. Beyond their silky smooth capabilities, the resonance control on each filter can be pushed to self-oscillation, resulting in four sine tones that track over four octaves! Tone is the perfect companion to Qu-Bit's Chord polyphonic oscillator.
This version of Tone features a BLACK faceplate!

Self oscillation with v/oct tracking across four octaves
This second part of our series on physical modeling synthesis with eurorack modular synthesizers covers modal synthesis. Modal synthesis utilizes many resonant bandpass filters as a resonator which can then be excited by many different types of impulses or sounds. Since most modal synthesis models use dozens or hundreds of bandpass filters digital implementations are more practical, but we put this together with analog bandpass filters to see how it would work.
