Hello all, I just ran into a situation where my Ensoniq Expression Pedal is not = compatible with a new USB-MIDI controller. Is there one standard for = wiring a passive expression pedal, or is there more than one? The Ensoniq pedal is wired with Ground on the Sleeve, Power on the Ring, = and the wiper signal on the Tip. The USB-MIDI controller is putting out Power on the Tip, and expecting = the signal on the Ring, but if I push the pedal to minimum then it = shorts out the power! Clearly, the two products are not compatible. I=E2=80=99m wondering whether this is common. I really only have one = pedal, so I=E2=80=99m not familiar with whether everything is compatible = or not. Taking a quick look at the Oberheim Xpander Service Manual, it seems = that their Pedal inputs are not wired to provide power. They=E2=80=99re = evidently designed to expect the pedal to have its own source of power = for CV. It seems to be a TS jack, but at least the signal is still on = the Tip. Brian
