Tinkering with the capacitor sounds like a safer bet than pushing the CV into strange regions (frequency depends on 1/Cf so should be fairly predictable, at least if you hand-select some nice values). Hopefully you won’t get too much noise or random capacitances from the wiring. Worst case you can build [a few more](https://lookmumnocomputer.discourse.group/t/my-build-progress/345/169) 😃
