I’ve been struggling trying to setup an expression pedal with my Helix using MIDI to auto turn on a wah block. I have a Morningstar MC8 controller. I plug the expression pedal into one of the extension inputs on the controller. I was successful in configuring the expression pedal and Morningstar controller to bypass/enable a wah block when moving the expression pedal. However, the expression pedal turns off the wah block whenever it is below 50% of the sweep. I have the setting on the Helix to turn off when the sweep is under 5%, yet that setting doesn’t seem to have any impact on what happens. I’ve set the wah block to bypass and change position via MIDI CC#15.
This is a video I’ve uploaded to YouTube that shows what happens:
Sorry no one replied yet. I’ve got an HX Stomp. I will see if I can do it on my Stomp. When I was looking at the manual earlier, it mentioned an expression pedal setting to auto turn off block if exp pedal is not being used for 100 ms (1/10 sec) - perhaps that is what is occuring?
James - I’ve got firmware version 3.8.5 and editor 1.1.5, and I don’t see ‘Send CC on Engage’ or ‘1 → ML5’ as choices in the drop down box. I’ve got PC set to zero, ‘Send to all MIDI Channels’ set to ‘Yes’. Here’s a screen shot.
I’ve sure I’ve left out a lot of pertinent information. What else do I need to add?
