Command Center - Midi commands with Snapshot changes

[Kfletchah]

Hello all!

 

I'm new to my Helix StadiumXL and working on sending some midi commands to my amp.  

 

Question:  In Command Center, can you send midi commands when you switch snapshots?  It appears only able to do so using StompA or B and using the commands triggered loading the preset.  Just wanted to double check I'm not missing something easy

 

I can make it work using stomp mode but it would be nice to attach a midi out command to each snapshot switch.

 

thanks!

All,

 

I was making this too complicated ...  I WAS WRONG - for those who read the two responses I just deleted.

 

So after much trial and error it runs out the instant command (thunderbolt) feature in command center is much easier than I thought for sending MIDI commands via Snapshots.  Or as Mark said in the movie "Renaissance Man" ... "Too easy drill sergeant!".

 

Unlike the OG Helix Floor were I had to use a instant command for each snapshot, in the Stadium I start with snapshot one.  Then I go to command center and select just the first instant command thunderbolt.  For my amp I will only have to use MIDI channel one using CC as my command selection.  I will start with my mesa JP-2C channel one which is CC#20 and set it for snapshot control (in the Stadium app it is a right click on CC# label then use the slide bar to enable)(on the Stadium itself you will see it pop-up when you touch the CC# label if enabling touch).  64 will be my on value and I am testing various wait commands currently using 2 ms; not sure but I may just set it to zero later after some final tests.  Then I just activate the snapshot I want to change the CC# value for, make the change, and done.  So you only need one instant command in my scenario with variable CC# YMMV.

 

It may seem like more work to go between home change snapshot then back to command center or you can have the Stadium at your computer/laptop while working on this for a little less work.  It almost felt like an Easter Egg until I read and read and then read again within the manual and then the lightbulb turned on in my pea brain. <darn it>

Ok. I gotta try this. Thanks for spending the time on this!

Oh man. Thank you so much!  This works perfectly!!  
 

it took like 30 seconds once you helped this click in my head. 
 

Just assign the CC control to snapshot control.   Done. 
 

only had to use one instant command. 
 

Wow. Once again amazed by the ease of use with Line 6 gear.

Kfletchah,

 

You are welcome.  You helped me dig deeper sooner than I was going to so you helped me as well.  ;-) 

 

Just a heads up if you ever need more than one MIDI trigger, I am using 4 of the instant commands for a preset using 4CM with my Mesa JP-2C.  It took a few seconds to wrap my head around the math matrix for this.  I have one for the channel selection, one for the reverb, one for EQ1, and one for EQ2 ... so far.  I had to be sure that I sent a EQ1 off command when sending an EQ2 on command and visa versa.  Then I am using a footswitch independently to turn on and then turn off the Shred feature via toggle and two MIDI commands for the single footswitch which turns the color ring on and off as well.  Once the light turned on the possibilities are only limited by my own mind.  

 

Anyway, thanks for seeking an answer to your need.  And a shout out to Line 6 for this new methodology.
