<p><span style="font-family: verdana, geneva, sans-serif;">Thanks for your reply, Hannes. I looked at the patent. It describes a method to switch different CV sources to a conventional VCO. There is no PWM to control the integrator slope, so my idea doesn't violate Moog's patent!</span></p>

<div dir="ltr">The design looks pretty similar to the core of a Moog VCO patent from 2016 (which references two of the Hohner Organ sound generator patents that I've researched).

<p><span> A while back (2022), I had an idea for an oscillator design which could be used in modular or hybrid synth's, but I have not yet tested the concept. The oscillator may be digitally controlled or voltage controlled, or both at once. I'm not sure if this technique has already been tried and proven. I haven't seen any evidence of it, so I would be grateful if anyone with a greater knowledge of the art can tell me if this is a novel idea, or a concept that has appeared before. (See attached summary.)</span></p>
