I ran plumb out of whale oil! (And here I thought it might glibly go without saying that the manual was read.) Still, when read, I took it to mean the left input to be the carrier (instrument) i.e., me, the instrument, not to be the input TO the instrument, i.e., the thingy inside the Eclipse. But that's when lamplight sputtered out. And the fading text, "feeds the modulator," I thought it was feeding me, the modulator! The Space Modulator!!
Er…. something like that. Thanks!
