Line 6 Helix Stadium Talk

[DanRad]

Yeah. I don't know why I'm just now noticing this, but to me it feels really strange/not right for the mod wheel of a keyboard controller to be locked in to changing the values of an expression pedal. For some reason that I need to investigate further, changing the Global and Bypass Control channel from 1 to 2 worked last night to filter out the mod wheel, but now it's back to the way it was before. It's also definitely not just a Helix thing. The Boss GM-800 is also doing very funky things in response to the mod wheel.

I think I have a workaround that I'm going to try this afternoon that should fix the problem on both.

Well, crap. I tried remapping CC 1 to CC 16 using the MIDI Events Processor. I'm still getting this bizarre behavior.

I also have the Global MIDI Channel set to 1 and the Bypass/Control MIDI Channel set to 2. Are those both incoming and outgoing?

@mbenigni, you do a lot of synth stuff. Do you have any idea what's happening and how I can fix it?

Yeah, I've thought about jumping in a couple of times, but I'm not sure I'm following the problem entirely. No help that I've been out of the Helix/ Stadium loop for so long. There are probably others (e.g. DI) better qualified to answer.

You're trying to use your mod wheel to target the Stadium's onboard synth engine's mod parameter, but that mod parameter is also responsive to the expression pedal - do I have that right? The general idea in situations like this (where devices have overlapping default CC#s) is to get each of your target devices on entirely different channels. But if both devices are subsystems in the Stadium, then it comes down to how configurable each of them are. (For instance, can you change the MIDI channel of the Stadium synth block, or is that a single global setting?)

Sorry, I have more questions than answers:

"I'm still getting this bizarre behavior." Which bizarre behavior? Remapping to CC16 should have - if nothing else - disabled your mod wheel, no?

"I also have the Global MIDI Channel set to 1 and the Bypass/Control MIDI Channel set to 2." I don't actually know what the Bypass/Control MIDI Channel is.

I may just take this to a direct message with Michael — though @Digital Igloo, if you have any thoughts, please jump in!

I would change the midi settings on the GM and HX end vs the controller end.

Helix/HX responded on one MIDI channel (Ch1 by default) and any MIDI CCs not reserved for global functions could be mapped to control any parameter. But as we added more global MIDI CCs (for example, controlling the 6 knobs below the screen, <PAGE/PAGE>, and Save), we'd eat into available assignable CCs.

So with Stadium, we split them onto separate channels. Global CCs control a wide variety of functions (EXP Pedals, XY controller axes, tap tempo, knobs, Looper functions, etc.) and we plan on adding more in the future. Bypass/Control CCs are assignable by the user so you can quickly map, say, Fuzz on/off, Amp Gain, Reverb Mix, or Delay Feedback to switches or knobs on your controller. The Global CC channel and Bypass/Control channel should always be different.

Stadium also add the ability to control bypass and parameter min/max from notes on your MIDI keyboard/pad controller. Incoming CCs and notes can now be assigned via MIDI learn in two seconds.

But which settings? I changed the Bypass/Control channel on the Helix. I can't find a similar setting to change on the GM-800.

Any idea why Stadium's EXP 1 would still be responding to a modulation wheel transmitting on Channel 1 when Bypass/Control is set to Channel 2?

Okay. I'll try not to take up much more time on this thread with this, but changing Global to 2 and Bypass/Control to 1 fixed it. That doesn't seem right, but there it is.

 

[JiveTurkey]

So in just quickly looking at the app without my GM connected; I see this:

Thing is; this looks like I just assigned CC2 to trigger CTL1 switch which is assigned to the part modulation functionality. So it's still using up an onboard switch? I'd probably find a preset with the mod wheel programmed to one of the switches. I believe there is at least one preset with that mod switch configured? It's been a long time since I have dug into anything other than the 4 gigging presets I use.

 

[mbenigni]

Doh, I completely forgot the GM was part of this scenario.

Based on DanRad's issues, I'd be inclined to put the controller and the GM on a MIDI channel well removed from any/all Stadium channels.

My brain is fried. I'm going to give this a rest for a bit and come back to it.

Because EXP 1 emulation is a Global CC, which defaults to MIDI Ch1. Set:

• Global Settings > MIDI > Global MIDI Channel to something other than 1, but different than the Bypass/Ctrl MIDI Channel
• Global Settings > MIDI > Bypass/Ctrl MIDI Channel to something other than 1, but different than the Global MIDI Channel

For example, your GM-800 could be Ch1, Stadium Global could be Ch2, and Stadium Bypass/Ctrl could be Ch3.

Okay. I did that, and as of this moment, everything appears to be working properly. Thanks, everyone, for their assistance, and apologies for momentarily hijacking this thread.
