Operate two CME Xkey 37 LE in parallel on one DAW track

[L.B.]

I already use a CME Xkey 37 LE. Poly aftertouch and the small desktop footprint are great.
Has anyone tried running 2 CME Xkey 37 LE in parallel on a DAW track. I would like to tune one CME up 3 octaves to do this. So I could address a total of 6 octaves with 2 CME Xkey? Thanks.

There shouldn't really be any difficulties in doing that unless the DAW in question doesn't allow multiple simultaneous inputs to the same track. I used to use two Xkeys in Studio One, but I wasn't able to do it in Notion (from the same company) since it doesn't seem to be able to accept two input sources to the same track.

Some decades ago there was MidiYoke: a virtual midi patchbay. I think it could merge two midi streams into one.
Probably 32-bit only, so no option these days...
