And especially there is no economical or technical reason, why Roland did not use log potentiometers in the mixer. For instance the potentiometers for the LFO-amount at the VCO and at the VCF _are_ 100k log sliders. So they had the right (log) parts in the drawer, but used the linear ones for the mixer - assumingly on purpose.

Good points, and an interesting example.

Although the polysynth mixing-separate-VCOs situation is different, perhaps it isn’t *so* different, and maybe linear response makes more sense/feels better.

Try it, I suppose. Always the answer.
