On my E1 Mk2, the value of a parameter regularly jumps in big steps when I touch or turn a knob. This happens a few times a day. Usually the parameter jumps to the minimum or maximum value. I can’t figure out what causes it. So I can’t reproduce this behaviour either. Does anyone have any suggestions on the cause and solution?
I am using firmware 3.6.1, Ableton Live and Windows 11. The E1 is connected via a USB hub with its own power supply and a good cable.
Might be the power is too weak. Are you using a non powered USB hub? Try connecting directly to the PC (PC not on batteries)
I am using a powered hub. But will try connecting directly.
Could also be a midi loop. Which preset?
Is it a parameter associated with a specific knob. I mean, is it always the same physical knob? And would it be possible to test it with a simple preset (such as Electra One App) and without Ableton Live running?
This has been happening with my two mkII as well. It happens when I twist the knob too quickly after initially touching it.
It happens due to the knob-touch sensor realising a knob touch too late causing adjustments made before the knob-touch sensor’s reaction to cause a spike in the acceleration calculation.
What usually works is touching the knob for half a second before starting to twist the knob.
I have this everywhere, in my desktop’s USB hubs (multiple, all externally powered), on my MacBook Pro 16 (2021 with M1 Max) with and without power.
I think the upcoming v4.0 will fix this.
Thank you for all the tips. I am not yet seeing a pattern when the jumps occur. Therefore I can’t force them either and thus test possible solutions. So I am going to pay a little closer attention to exactly when it happens. I’ve already improved the power supply. And no jumps since then. I use @jhh’s Ableton Live MIDI Remote Script, by the way. Working without Ableton isn’t really an option for me.
