Bug reports - Big jumps when turning e.g. the mid frequency knob in simple eq block

[Sidolini]

Hello there,

I'm new to this forum. I have an issue with my Helix Stomp: for example when I turn the mid frequency knob in the "simple eq" block to go from let's say 400 Hz to 700 Hz, I have to turn very very slow, otherwise the frequrency jumps from 400 to 900 Hz or it jumps even backwards to 200 Hz although I'm turning the knob clockwise. 

This is only one example. The same thing happens when I´m setting the low cut in a "parametric eq" block or the crossover frequency for a parallel path. And the issue is not related to one specific knob, but  to one of those 3 knobs under the display. 

I hope I´m clear enough in the description. My unit is two years old. I guess the problem was there right from the beginning, but I don´t remember exactly. I guess at the beginning I haven´t taken too much notice of it. 

I have already done a factory reset, but the issue is still the same?

 

Does anybody has any ideas?

Hi,

 

I’m not sure, but you may be experiencing this (link below).
 

It was mentioned that there might be a bug, although the comment from @codamedia says that the issue did not happen on his hardware LT and Stomp, which seemed to indicate this may be more a software glitch than a real bug!

 

Hope this helps/makes sense

Sounds like this is after the 3.5 update where they improved the speed of knobs, where you can quickly turn it and get to the max, or slowly turn it and get a precise value.  If the encoders are not working correctly, users have reported complete inability to adjust anything except jumping from min to max, and nothing in-between.  

 

"Encoder ballistics have been drastically improved. For example, tonestack values can go from 0.0 to 10.0 with one turn"

Thanks, but in my case the issue only concerns the 3 encounters below the display.

Thanks. Yes, it seems the encounters are not working correctly, because as I said they not only cause too big jumps, but also backwards jumps.e.g. I´m turning clockwise and the value (in my example it´s the mid frequency parameter in a "simple eq" block) jumps backwards to a lower value. Is there anything I can do about it?

I personally build all my presets using HX Edit.  If the knobs are not usable for you, then just use that.  There is also pedal edit mode -- use the expression pedal/buttons to adjust parameters: 

 

So if you absolutely need to adjust something and you have no computer nearby, then use that.  

If the unit is several years old, the only thing is to have it shipped to Line 6 for a proper repair,  Local repair shops that are authorized will not fix it properly, at least in my experience.  So I'd just use the workarounds and leave it alone...

It's a hardware problem of the rotary encoder. Contact cleaner can fix it (at least temporarily).

 

Replacing the encoders can and has been done by members in this forum.
