ccornel Posted November 28, 2015 Share Posted November 28, 2015 Good morning. I can't figure out what i'm doing wrong. When I add additional expression pedals the sweep goes from 100% at one end of travel to 0% in the middle to 100% at the other end. I have two of the Mission EP-1s that i used with AXE-Fx. I've tried to learn the controllers, make adjustments on the Helix to the percentages, regular and TRS cables. Nothing working. The built in pedal works fine until i add the outboard pedals then it acts up too. I'm hoping it's something stupid i am missing since i don't see anyone else having this problem. Thanks, Carl Corneliusonn Quote Link to comment Share on other sites More sharing options...
JonnyPM Posted November 28, 2015 Share Posted November 28, 2015 There might be a control within the Pedal Assign area that controls the sweep of the effects pedal, like Linear and Logarithm or something like that. Seems like I ran into something similar to what you're experiencing. IIRC, Linear was the one that had the more regular sweep. Quote Link to comment Share on other sites More sharing options...
a2dconverterguy Posted November 28, 2015 Share Posted November 28, 2015 Hello CarlYou will need to get a Line 6 specific expression pedal as they are wired differently from Roland type expression pedals....The difference is the use of a 1/4" mono cable as opposed to a stereo cable.... Also, Line 6 uses a 10k ohm pot, but you can use most other values with the Helix without difficulty.You can probably re-wire yours... I Included a modification drawing for your Mission EP-1... (the third diagram includes the addition of a switch so that you can switch between the stock MIssion EP-1 and Line 6 Functionality.)I hope this helpsSeeyaJoe PS.. Mission sells an EP1-L6 specifically for Line 6 devices... Here is some info from the Mission website.. *Note that the EP1-L6 is the only Mission expression pedal that can be directly connected to the expression pedal input on Line 6 devices. Other Mission expression pedals are not compatible with the Line 6 pedal interface. Quote Link to comment Share on other sites More sharing options...
ncockerill Posted November 30, 2015 Share Posted November 30, 2015 Ugh -- so this means my Roland EV-5 pedal won't work with the Helix? Quote Link to comment Share on other sites More sharing options...

PeterHamm Posted February 22, 2016 Share Posted February 22, 2016 Ugh -- so this means my Roland EV-5 pedal won't work with the Helix? Actually, it probably will. Also, on Helix, a LOT of other pedals work. One of my EXPs is an ordinary Ernie Ball VP Jr. with one cable connected from EXP to the output jack on the VP.

Other Mission expression pedals are not compatible with the Line 6 pedal interface. So I opened up my 2010 model EP-1 pedal to do the mod- and it looks nothing like the prints. Mine has a single 20K ohm pot with I believe 3 wires attached. Why is it so much different than the schemes ? And yea it works well on KPA and Fractal stuff... Now what?

a2dconverterguy Posted February 23, 2016 Share Posted February 23, 2016 Hey Spikey... Solder the wires like this... don't worry about the pot value I hope this helps seeya Joe Quote Link to comment Share on other sites More sharing options...
spikey Posted February 23, 2016 Share Posted February 23, 2016 Hey thanks for that! I assume that I just need a regular 1/4" guitar signal cable to run it then? Quote Link to comment Share on other sites More sharing options...
a2dconverterguy Posted February 23, 2016 Share Posted February 23, 2016 Hey Spikey, Just a standard TS cable will work and the Helix will auto-calibrate the pedal automatically. Good-Luck seeya Joe Quote Link to comment Share on other sites More sharing options...
thrones Posted May 1, 2016 Share Posted May 1, 2016 My EV-5's appear to not be compatible, bummer cuz I have 3 of them and they're my favorite expression pedal. Has anyone had success with EV-5's? Quote Link to comment Share on other sites More sharing options...
a2dconverterguy Posted May 1, 2016 Share Posted May 1, 2016 Unfortunately, You'll have to rewire the EV-5 to work... Quote Link to comment Share on other sites More sharing options...

Ka5par Posted May 2, 2016 Share Posted May 2, 2016 Unfortunately, You'll have to rewire the EV-5 to work... So, it isn't possible to rewire it through the min vol pot? Quote Link to comment Share on other sites More sharing options...
groovedggr Posted May 2, 2016 Share Posted May 2, 2016 I connected an ev5 and had problem but after adjusting min volume it was ok. Maybe I should try it again and see if it held good. Quote Link to comment Share on other sites More sharing options...
Apsi93 Posted June 5, 2016 Share Posted June 5, 2016 hi guys i got a roland fv-500L and i have the issue that the wah is at 100 percent when heel is down and at 0 percent when toe is down. how do i get it the other way around? Quote Link to comment Share on other sites More sharing options...
phil_m Posted June 5, 2016 Share Posted June 5, 2016 hi guys i got a roland fv-500L and i have the issue that the wah is at 100 percent when heel is down and at 0 percent when toe is down. how do i get it the other way around? Well, for now, you can simply set the minimum and maximum opposite of what they currently are. Set it so the minimum is 100% and the maximum is 0%. There isn't a polarity setting for external pedals right now. You could also make or buy an adapter to switch the polarity of the pedal.

regalpierot Posted June 6, 2016 Share Posted June 6, 2016 That's hilarious, exact same issue with fv-500, was wrecking my head as to why it would do it but the switch to reverse min\max values resolved the problem. Expression pedals can just be the weirdest things, some I have work fine with a certain set of devices and either not at all or with weird results with others. Really wish manufacturers had just standardized. Quote Link to comment Share on other sites More sharing options...
vmcgreborn Posted August 11, 2017 Share Posted August 11, 2017 Is posible only change cable conections instead of modifing the pedal, i have a mission ep-1-r and a behringer fvc-100. But i think using a phone cable instead of a trs solve the problem in ep-1-r because slave an hot are join for the simple use of this kind of cable.

espenlundolsen Posted September 2, 2022 Share Posted September 2, 2022 Wanted to share a mod I did on my EP-1r (as far as i understand just using a mono-jack won't work because the tip will be grounded in either end og the potmeter?) The EP-1R is wired as a traditional expression pedal, and it has a switch for reversing the polarity. I wanted to use this pedal on my Helix and thought I could use this switch to switch between Line6-wiring and "normal" wiring. The reverse functionality/polarity switching I think mostly can be solved in the setting - at least it is possible on the Helix. Well, I ended up with wiring up this modification. Just tried it on a Helix, but works perfectly in that mode. Probably will try it on my keyboard. Does anyon see any flaws in my wiring?
