Is there a way to bypass pedal calibration?

[Dave Merrill]

Ding-ding, we have a winner. Sleestak, you solved it. Huge thanks!

In the setup > Pedal calibration function, it would appear that the curve of the modifier assigned to the pedal in the currently selected preset has, very surprisingly, an effect on the calibration (!!!)

I selected an empty preset (therefore no curve, no modifier, nothing assigned to the pedal) and now it calibrates properly as it should.

I'm baffled that the calibration process would even have awareness of a preset, let alone curves on modifiers, but...

Anyways, thanks, now I'm good to go (though somewhat mystified).

Interesting, and IMO weird, that the current preset affects pedal calibration. Is that a bug?

That is bizarre and must be a bug.

A Modifier curve could be assigned to multiple parameters in a preset and each could have it's own curve.

Could you post a screenshot of the offending modifier setup? I'd like to see if I can reproduce it.

Also, what @Sleestak was saying is not what you're reporting. He was saying that the curve will apply to the calibrated pedal results onto whatever is being controlled.

This is most definitely a bug if that’s the case. The curve should be modifier assignment specific.

This is easy to test. Let me try some things.

I'm not seeing any sign of this here. (Pedal 2 volume modifier w/ mid value lowered to zero, Turbo fw 31.03) If you can reliably recreate the issue it might be good to document the process on video.

Calibration does create what looks like a 10% dead zone at each end though, based on the pre vs. post-calibration meters. That could probably be reduced quite a bit (to maybe 1-2%) without causing many real issues IMO. (A user could limit the range of movement during calibration if value flutter at min/max was occurring. The only way to avoid this dead zone now would be to use an alternate calibration device like a switch that gets pretty close to 0-100, then connect a pedal that reads 10-90% or so at most and deal with that in the modifier settings, if it stops a bit short of either value.)

So if what you're saying is true @Dpoirier then I should be able to use a preset with a single block in it, assign Pedal 1 to be a parameter modifier in that block, set an EXTREME curve on the modifier, run calibration on Pedal 1, and it should have an impact on the min and max points noted during calibration. If I set the curve on the modifier back to linear I should be unable to sweep the entire linear range.

Edit: Yea, I cannot recreate this problem here. Mappings for Pedal 1 in the preset and their modifier curves have no impact on the calibration process and the pedal responds excatly as expected pre- and post-calibration no matter what modifer curve I have on a controller on a block in the preset when I'm performing the calibration.

FW 31.03 here on a non-turbo AFIII.

If you can create a video showing the issue @Dpoirier, someone can look in to it further. But if both @Bakerman and I can't repro it, it's seeming unlikely that your explanation of what was wrong and what fixed it isn't correct.

My suspicion is you were calibrating the pedal, then attempting to use it on an modifier with a non-linear curve and confusing the non-linear curve with a bad calibration process. But it's a guess. If you have a video that highlights the problem, it will go a long way towards making things clearer.

I have no dead zones created by calibration when I calibrate either an EV-1 or an EV-2 here. It's going to be highly dependent on the pedal and the sweep of the potentiometer that pedal does. Most pots have a dead zone at the extreme ends of the wiper range and a well-built pedal won't rotate the potentiometer to the extremes.

It probably won't be noticeable during typical pedal use, and looking again it might just be 5%, but this illustrates it. After calibration the pre-cal meter can rise a few pixels from the actual minimum read during calibration (A-B) before the post-cal (and any modifier) value begins to change (B-C). Same deal at the highest values.

I don’t have that here with my EV-1 or EV-2.

I addition to no rise on the calibration screen, the curve ball is exactly at it’s min and max when me pedal hits min or max on its sweep looking at a modifier screen. There’s no dead zone.

The Moog I have on my FM9 board absolutely has a dead zone in the heel down area. The last bit of travel doesn't change the overall resistance and so there's a bit of movement after the ball hits the extreme end of the modifer curve.

Here's a screen shot of my modifier. When I calibrated my Pedal with this preset selected, I ended up with a severe difference similar (but more extreme) to the photo posted by Bakerman. In my case the pre-cal bar could be up to about 30% before the post-cal bar even budged. Now that I have performed the calibration again (while on an empty preset with no pedals assigned or modified) it's back to normal, perhaps with the small 5% to 10% dead zone described also by Bakerman. I can live with that (but not with the wacko 30% I had before).

So you have Pedal 2 mapped to External 10?

I'm going to say, all these details are important as we try to get to the bottom of this. Maybe you could post the preset and your global settings? That would be more expedient than going back and forth here as we try to recreate the problem, only to find out your settings aren't the same as ours.

With this setup, I still can't replicate your problem. I have Pedal 1 mapped to External 10. And when I enter calibrate mode for Pedal 1, the sweep shown on the bars on the calibrate screen is exactly correct: the bars go from 0 to max as I sweep the range of the pedal, both before and after calibration.

Unless you can provide a preset and your system settings that show this happening consistently, I'm going to continue to believe this is some sort of user error.

Yes, correct, my Pedal 2 is mapped to external 10. And what you did to try to replicate seems about right.

I'm willing to "accept" the user error conclusion, though I still have no idea what the error would have been. Calibrate while on this preset borked it. Calibrate while on an empty preset fixed it. I'm happy going forward. I don't necessarily need to know why it borked (though it leaves me a bit insecure). Currently I don't dare trying to replicate it again on my end (by attempting to calibrate while on the suspicious preset)..
If I did, and it borked it, at least I'd have the option of sharing the preset to further investigate. If I did, and it didn't bork it, then I'd have to conclude that some unknown weirdness (including potential user error) occurred the first time but can't be replicated. If I find time where I can afford the risk of borking it again, I might do that. In the meantime huge thanks to all for trying to resolve and/or replicate, and apologies for wasting your time.

apologies for wasting your time

If this really is a bug, it’s pretty deep and serious IMO. So not a waste of time, per se, but I’d like to get to recreating it to make this truly useful. Otherwise it remains as a rake on the field for others to step on.
