Hi all,
Iām trying to get headrush core to work with stage traxxx, have a camera adapter for iPad with an otraki usb to midi in and out cable. Does seem to be reading or sending any midi messages
Use with headrush Core
Hi. I don't have a Headrush pedal so can't offer any help in the specific setup for that device but I can assure you that controlling external guitar pedals (any externalMIDI device I guess) work just fine as I have ST3 controlling my Fractal Axe FX Rack and my Fractal FM3 no problem. Just be sure to match MIDI channels, select the correct MIDI command etc. Good luck, stick with it, it does work! 
- Edited
Please provide mroe information to make it possible/easier for people to help you.
Have you got ST successfulyl sending MIDi to other devices and ONLY the Headrush Core isn't working, or is this the first MIDI connected device?
What commands are you sending from ST and how? Lyric sheet (provide some examples)? Global settings (again, provide example).
Walk us through your Headrush MIDI config (like a check-list for yourself). What MIDI channel is it receiving on?
The more you give us, the better/faster people can help you. Otherwise, I could write 2 pages of what it MIGHT be (which I'm not going to do as I value my time)
For ref: Link to Headrush Core manual - https://cdn.inmusicbrands.com/HeadRush/core/HeadRush%20Core%20-%20User%20Guide%20-%20v1.0.pdf
MIDI spec is on p57
Interestingly, it doesn't seem to support any Program Changes? So you are limited to turning FX Blocks On/Off, Footswitchs (assuming this is a toggle. Recommend you don't use these as you always have to know the starting state for a toggle to be useable), and Looper controls.
