I firstly thought that it could also depend by the gate or the envelope generator you’re using (if any), then I recall that some VCA are used not to close completely, finally I read that your VCA is mounted on a low cost case so I am afraid it might depend on the floating ground. I had similar issue and users here had helped me. That kind of case need to be grounded. But wait for further advice coming from other users.

I’m also using a recently purchased Doepfer A140-2 which I completely love. It pairs with the A132-3 really well and is so compact and useful, especially for stereo signals and twin voices. Would recommend it to anyone wanting to save HP. > > >
