I have a Nektar NX-P passive expression pedal, which is basically just a potentiometer with measured range 560 ohms to about 12 kilohms. I successfully connected it to a volume block in one of my presets in my new HX Stomp XL, and it shows the level changing from 0% to 100% when I move thew pedal, and the volume of the audio output does indeed change.
However, I want the range to be from, say, 60% to 100% over the full sweep of the pedal, so as to be able make minor adjustments in a live setting with better precision.
On my Line 6 HD500 unit (which the Stomp XL is intended to replace), you can easily change the low end of the range of the built-in volume pedal by raising the pedal to the full-up position, adjusting the level to the desired value with correct knob, and then saving the preset. But the same procedure isn't working for on the HX Stomp XL: I can adjust the low-end level when the pedal is up and stationary, but as soon as move the pedal, it reverts to 0% I haven't yet found any way to make my adjustment stick. Is this a bug, or am I missing a step?
I couldn't find any mention of this issue in previous posts, so it might just be something stupid I overlooked.
(I've only had the unit for a bit over a week, and when I got it, I updated the firmware to the latest version—I don't remember the version no. offhand)
