It'll work as a mixer... but then you give up the ability to use it as VCAs. You could press the Maths module into mixing duty if need be.

Thanks, that's good to know. Is it a case of jumpers at the back to switch between VCA/Mix modes, or is it dependent on how it's patched? If it's the former, I'd maybe be able to live with it, as that's kind of versatile.

Good point about the smaller clones. I'd envisaged the bottom row as a bit more spacious for ease of use and playability, but maybe there can be some compromise.
