Hey there !
A bit late to the party, but if you’re still around, I’m stuck on something quite similar. Your solution seems like a good path to follow. I was wondering tho, did you try it on a packaged build ? Or was it just in editor mode ?
And also, did you have to set up something specific in Unreal to have it using 8 channels ? Or was it sending by default to those 8 buses ?
Many thanks
