Ct = -0.1; // circle translate? Not sure. Pad = 0.2; // this is a ceramic 104 power cap like C5, C6, C8, C9, C11, C12. C10, C14 too small for film; is film needed? Notes: Could make the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? Seven-segment display. Can be done, but requires a trigger-sized pulse on input. - Portamento (aka slew rate controller aka glide). Knob version fairly simple. - CV out /* [Default values] */ // --------------------- // Degree of detail in the mid surdos.
