Pedal position inconsistent

amosmax · Nov 23rd 2023

Hey All,

So, I recently changed my board a bit and added two Dunlop mini pedals. They're great space savers and feel just like a big pedal (at least to me).
Unfortunately, it seems the Kemper is not tracking the pedal position correctly. I have a wah configured for most of my rigs with the toe-position-bypass option enabled. However, on occasion I will change rigs and the sound will have the wah in a "half-cocked" position, even though the pedal is all the way forward.

Sorry for the long-winded intro, but I figured what I'm asking wouldn't make sense otherwise. Anyone have an idea what the problem may be? Is there a way to force the Kemper to "assume bypass" on an effect after a program change?

Thx in advance for help and/or pointers! You guys all rock 🤘

If you want that, you must save the Rig with the wah off and then move the pedal to activate

Burkhard · Nov 24th 2023

If you use Pedal Mode "Bypass @ Toe" in all wah effects in all Rigs, that should work.

Have you pressed "Calibrate" and performed a complete sweep of your expression pedal?

Does the bar representing the Wah Pedal on page Pedal Links reach the maximum corresponding value 127?

Or if you hear the wah effect while your pedal rests in toe position, is the value at 127?

All - thank you for your help!

Kellerblues that sounds plausible, but how do I do that (enable pedal to activate)

Burkhard No, I did not calibrate the pedal. On any individual Rig, the toe position "activates" bypass, so I just assumed that the pedal was calibrated correctly. I will double check.

Again - on any individual rig everything works as it should. It's on Rig-changes (example: in performance mode, from "1" to "2" on the remote) when this randomly happens. I'll try to reproduce and get a video of it ....

Ok, please check the value of the Wah Pedal controller on page Pedal Links.

Perhaps it's a mechanical issue: When you initiate a Rig change the pedal slightly moves away from toe position.

And I suggest to calibrate anyhow. Perhaps the range is not maxed out and the grace area at the toe position too small.

Is there a parameter for the grace area?

Burkhard · Nov 27th 2023

No, we hesitate to flood the product with options for corner cases. The Bypass @... functions work in the vast majority of cases. And in this specific case we don't know yet, what the root cause is. Perhaps there is an issue with that pedal.

Which makes sense ofcourse.

My problem is when i am on a stage that is not solid. The vibrations trigger the wah.

Burkhard · Nov 28th 2023

In that case activating the effect via pedal movement is perhaps not the right approach.

I'm using Bypass @ Stop, which has no grace area at all, and I have no such issues.

Have you checked, if perhaps the pedal is mechanically too loose, or considered a pedal with a toe switch?

Kim_Olesen · Nov 28th 2023

Hey i will give that a go.

I'm using Bypass @ Stop

I use Bypass @ Stop for wah, too. It works very well for me.

Wheresthedug · Nov 29th 2023

I’m now on bypass@stop too. I used to use the toe switch on the mission pedal but I don’t like the mission and will be replacing it shortly so wanted to check if bypass@stop was reliable enough for me. So far I haven’t had any issues in several months but haven’t experienced a wobbly stage yet. The advantage of bypass@stop over bypass@toe for me is that it has double security. If I leave it at the toe position it is also “stopped’ by definition. If I stop anywhere else (accidentally stop at heel because of a heat pf the moment brain fart for example) it is still “stopped” and therefore bypassed.

Interesting. Perhaps that's a simple solution for me as well. What's the delay between "stopping movement" and the wah going to bypass?

Now i remember why i am not using the bypass @ stop. I have been using it but it times out too fast for me. Burkhard can i suggest then a parameter for the “timeout lenght”?

Burkhard · Nov 30th 2023

I suggest to try Bypass @ Heel or Bypass @ Toe instead since those have a grace area and if your pedal is not mechanically too loose those should work.

So, it looked like the calibration was correct, but I went ahead and calibrated it again anyway. My issue did not happen during our practice session that night, but as I mentioned before, it was somewhat random to begin with.

Is there a way to visualize the actual numerical (midi) values on the pedal position somewhere?

Wheresthedug Kim_Olesen

Tried the bypass@stop - doesn't work for me. It removes the ability to do the "Zakk Wylde - half-cocked" sound ....

Burkhard · Dec 1st 2023

You see the values corresponding to the pedal bars on page Pedal Links. This page is either in System Settings (Head and Rack models) or in Pedal Settings (Stage). Soft knob 2 is Wah Pedal and the values follow the pedal moves. You can also simulate pedal moves witht hat knob.

Kim_Olesen · Dec 1st 2023

Thanks Burkhard. Will probably have some pre show time tonight to look into it.

So, I thought this was solved, but it reared its head again. This time I was able to reproduce it, but that doesn't mean I understand what's going on.

The attached video shows one way of how I was able to reproduce the issue, but it seems to happen at random other times as well.

To recap: I have a wah for every performance patch using the right pedal with bypass@toe. The morph difference on #2 is just a volume boost.

Any ideas? Should I open a support ticket?

Thx - M.
