MRP323 Posted November 20, 2017 Share Posted November 20, 2017 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? Quote Link to comment Share on other sites More sharing options...
HonestOpinion Posted November 20, 2017 Share Posted November 20, 2017 A lot of Helix users have found this video useful for setting up MIDI channel switching for their amps. This one is for Hughes & Kettner amps but it should be a similar process. 1 Quote Link to comment Share on other sites More sharing options...

Make sure you Set Helix MIDI Global Settings by going to Menu Button > Global Settings > MIDI/Tempo > MIDI PC Send (Page 2) > Off Quote Link to comment Share on other sites More sharing options...
pbatts Posted November 20, 2017 Share Posted November 20, 2017 The EVH 5150III 50w head uses a "learn mode" just like the JVM does. Here is a link to programming the JVM which might help. http://line6.com/support/topic/28901-marshall-jvm-channel-switching-with-helix-midi/ Quote Link to comment Share on other sites More sharing options...
MRP323 Posted November 20, 2017 Author Share Posted November 20, 2017 The snap shots were the issue. Switched the mode so the buttons were regular switches and it took the commands no problem and it's no longer playing leap frog when i change the channels. Thanks, everyone for the suggestions!

pbatts Posted November 21, 2017 Share Posted November 21, 2017 I'm not sure what you mean. Snapshots and MIDI work together perfectly. Quote Link to comment Share on other sites More sharing options...
MRP323 Posted November 22, 2017 Author Share Posted November 22, 2017 Each snap kept giving me a different midi setting because I was assigning the command to the button and not the snap shot. After I programmed the commands into the head and assigned each snap an instant midi command it worked perfectly. Quote Link to comment Share on other sites More sharing options...
