| br>Even though I built my Orbitals a few months ago, I've only just had a chance to put it through its paces.
Seems I have an issue with Row 1 CV out...the voltage seems to be unstable (i.e. patched into a VCO, it essentially wobbles/shimmers - not like an LFO modulating a VCO, but just an unstable, unpredictable wobble).
Row 2 is fine and CV out gives perfectly stable pitch as I'd expect.
Any ideas which bit of the circuit to troubleshoot ? br> br>
