I have been trying unsuccessfully to program my helix to switch all three channels on my EVH 5150III 50w head, via midi for a while now. I'm not very well versed in midi programming but I can program it to switch between two of the channels at a time. For some reason however I cannot set it to change more than one channel with out the program values playing leap frog and jumping around to different buttons, and sometimes it will literally just change the program value to some other random value (exp. i set it to 74 but when i press the button it changes it to 127).
Can anyone tell me why the values randomly change or have an EVH yourself and know a specific fix for this?
