Hopefully you realize that this statement....
Cactus Music
Of note is I tried to use asio4all with the Scarlett 6i6 and it only gave me 2 inputs , channel 3/4 and the SPDIF and the MIDI where all missing. So it certainly sucks as a driver replacement for a real audio interface
....completely contradicts this statement....
I think there where issues in the past but somehow I think asio4all is now improved and we need to re look at it in a different way.
Brand spanking new audio interfaces can be had for under $100 these days. Better quality used units can be had for about the same price. In my humble opinion, there is absolutely no good reason for using the smoking pile of garbage that is asio4all.
