On the Factors, you can use either cable – the RING is not connected. This means that my comment above is not strictly correct – the RING connection at the pedal is unimportant.
Hello- I’m using a Dunlop XL (DVP 1XL) 10k pot expression petal with just a tip sleep connector. When I operate the petal with H9 the parameter values go from say 0 (heel down) to 100 HALF way rocking the petal to 0 again at toe down. The specs on the petal say :Low Friction Band Drive” petal. Is this not a Linear taper as suggested by you. Is this a setting issue? HELP
