I am trying to get a 2164 SVF design to behave. I can't seem to get the frequency scaling right. It is very sensitive to CV. I thought you can make a volt/oct filter out of it. btw I am going off the Shruti schematic. Anyone got some stick time on this puppy?<span class="HOEnZb"><font color="#888888"><br>
