hesperis, I had the same problem. I've got several that convert from a stereo mini-plug to a 1/4" one, but the only one I have from 1/4" to mini is mono. I solved the problem by getting a patch cord that had a female 1/4" stereo jack on one end and a male stereo mini jack on the other. I got THAT at Radio Shack, but it's somewhat of a headache to use because the only one they had is about 15' long.
