geetar_geek79 Posted April 22, 2016 Share Posted April 22, 2016 To you guys who have the rack, can you try to set your midi base ch to Omni and try to send PC messages to an external device please (using midi cables)? Does the other device receive the PC command? I'm having a weird issue with my helix rack and I'm not sure if it's a bug or I'm doing something wrong. When I send PC command on a specific channel, it seems to go out fine. But when I set it to Omni, it doesn't seem to send the PC. Midi cables are fine; the other device is fine. I also sent a support ticket already but I thought I'd see if you guys have it too. Any ideas? Quote Link to comment Share on other sites More sharing options...
TexLefty65 Posted April 22, 2016 Share Posted April 22, 2016 I'm not a MIDI expert, but if I recall correctly, MIDI "Omni" is only a valid option for MIDI Input and not output (someone tell me if I am not correct about that though!) So, you can set the Helix Base channel (global setting) to Omni, but that means Helix will then listen and receive on any of the 16 channels, but it won't SEND any MIDI to all 16 channels. It looks like Helix just sends out only to MID Ch 1 if you have the global Base channel set to Omni and then the particular footswitch/pedal's Command Center MIDI Ch to Base, which seems to make sense. Are you getting you MIDI PC message sent out MIDI Ch 1 when you have the Base channel set to Omni? If you can connect your Helix MIDI Out cable to a computer and look in an app such as MIDI Monitor (on Mac) or MIDI Ox (Windows) and you'll be able to see exactly what Helix is sending.

geetar_geek79 Posted April 22, 2016 Author Share Posted April 22, 2016 Sorry but I don't have the capability to connect my Helix to my PC at the moment in order for me to view MIDI data using MIDI OX. My other device is an older Rocktron Patchmate that is set to MIDI ch1. It's a pretty straight forward device and I don't think that it is the issue. Its MIDI in connected directly from the MIDI out of the Helix. If the Helix MIDI channel is set to 1 and I change patches from the Helix using the preset wheel, the Rocktron changes presets along with the Helix. But if I set the MIDI channel to OMNI, the Rocktron does not change preset. It doesn't make sense to me that the Rocktron responds to the Helix on channel 1 but not OMNI.
