these wee vco ic’s are really good, i dont know why more people dont use them! other than the obviously limitations of linear response and reverse voltage control, i have yet to encounter any major issues.
with a bit of tinkering and snuffling (i have man-flu remember?), i can achieve a good range between 24hz and 1703hz with out any distortion, using only 9 components, which should lend itself nicely to to little drum synths and a replacement to the integrator/comparator vco i was using for the dub siren.
now where did i leave the co-codamol?
