Hi @Jake
I’ve just asked the XONE team on your behalf –
They’ve suggested to set the two K2’s to different MIDI channels as shown in this video – https://youtu.be/WKKINsUSqfc
Note that if you’re not already doing so, you can have one K2 connected using USB and a second K2 connected to the first using X:Link.
This will mean that both units show on the same main connection in Ableton Live, but when mapping, they will have different messages (i.e. this will prevent the ‘doubling’ issue).
There’s more on what the K2 responds to (MIDI to LED’s) in the guide here – https://www.allen-heath.com/media/XoneK2_UG_AP8509_3.pdf#page=17&zoom=auto,-274,823
You can also check out the template available with Control Surface Studio from remotify.io – https://remotify.io/product/control-surface-studio
If you need more info, you can contact XONE support directly using support.allen-heath.com 🙂
Hope this helps, and that the set goes well!
Cheers,
Keith.
