Finally got my rig home today and updated to 2.8, too! Looking forward to using the KoT...
So here's how I've got thing set up:
In the BandHelper App: (not the website...)
- in your project Setting/Remote Control:
-- MIDI Input Channel - this can be set to any allowable value, but all messages destined to BH must invoke this value. In my case, I use channel 5
-- And then set Previous Song/Next Song/etc to CC 80, 81, etc.
In Helix, in your preset, go to the Command Center:
-- for each button, set the MIDI Channel to whatever value you picked above. In my case, 5.
-- CC # will be 80, 81, 82, or 83
-- Value will be 127
-- Switch LED and name will be whatever you want.
I have my Helix connected to my PC, and using MIDI-OX:
-- First in the Options menu, select MIDI Devices. Under MIDI Inputs, "Line 6 Helix" should be listed. (There might be a number before it, like "2- Line 6 Helix")
-- Click on that input to highlight it, then click OK
-- next, under the View menu, select "Input Monitor..."
-- press the Helix button. You should see something in the Monitor window. DATA1 should be 50-53 (hex values corresponding to decimal 80-83). DATA2 should be 7F (decimal 127) and CHAN should be, in my case, 5.
This will tell you that your Helix is sending the right data.
With the Helix connected to my Android device through my MIDI interface (I don't have the right USB cable to connect the Helix to the Android directly), the MIDI Commander MIDI Monitor window shows:
"ControlChange cable: 0, channel: 4, function: 82, value:127"
In other words, exactly what you see, with one critical change - the MIDI channel.
** MIDI Commander counts the MIDI channel from 0, whereas BH and Helix count from 1, so what MIDI Commander says is channel 4 is actually channel 5 for everyone else in the equation...
So, this is a long way of getting around to saying that I'm pretty sure all you need to do is configure BH with a MIDI channel, and then specify that MIDI channel in your Helix command center programming.
And to test it, I got out of MIDI Commander, ran BH, opened up my set list to the first song, pressed the Helix button - and it works as expected.
Hopefully, the attached screenshot makess the Helix setup and MIDI monitor (on my PC) clear. Sorry, not sure how to show the screenshots from my Android.
