Mission Engineering EP1 L6 Suddenly Not Working with HX Effects

[C4TH]

Hi People,

 

I recently bought a Mission Engineering EP1 L6 to go with my HX Effects (I used a Dunlop Mini Dvp1 previously).

The EP1 has worked great for about 2 weeks with all my presets/snapshots. Then all of a sudden it won't work. Its basically not moving the "position" parameter or activating/bypassing. Sometimes it will move from 1 to 5% in the heel down position, but nothing above that. This applies to Wah, Volume and pitch. Its plugged into EXP1.

 

Any help would be great,

 

Thanks.

Test#1 would be the cable. Try a different one. Test#2 would be the EP1. Try it with a different device if possible. Test#3 would be a change in the Helix settings for EXP2 (e.g. an inadvertent change to the Max position). Then try a factory reset on the Helix (after creating backups, of course). If the problem persists after those tests come back with further details.

Thanks for your response Silverhead. 

 

Test#1 Cable didn't make a difference. Test#2 Tried EP1 with my POD GO and worked as expected. Test#3 Max and Min settings seem to be the same and are all set to EXP1.

I carried out a factory reset also, but still behaving the same.

 

Thanks again.

I believe the HX FX has two external pedal jacks. Have you tried the other one?

 

Also make sure your EXP pedal assignment (1 or 2) matches the jack you are using.

Keep in mind the EXP jacks are dual purpose.... Expression Pedal OR Ext Amp Control

Check your global settings for those assignments. They may have gotten changed to "amp control" in error.

Thanks @codamedia and @silverhead. I have now tried EXP1 and EXP 2 but no luck.

Global settings are set to the correct pedals.

 

One thing I have noticed though, is that I use EXP1 for expression and EXP2 for channel switching. If I make a change to EXP2 (Tip/Ring,etc) it seems to effect EXP1’s behaviour.

Try using a TS, not TRS, cable.

Have you tried restoring JUST the Global Settings? This might help if those became corrupt in any way. 

 

I believe on an HX FX this is it... 

Restore Globals: Hold footswitches 4 + 5 during start up.
