I will just write solution here if some people are stupid as i was ! hehe
I said in my first post : ASIO settings : Default buffer size : 512, Default bit depth : 16 --> Latency (input/output) : 15 / 31 ms.
I could not change the SLIDER for some unknown reason (not working, no sound)
But i did not try to change buffer SIZE !!! (and i know the smaller it is the faster is the signal...)...
So now... ASIO settings : Default buffer size : 128 , Default bit depth : 16 --> Latency (input/output) : 7 / 14 ms !!!
Ain't no crunchy bad sounds, looks clean. Did not try higher bit depth though. i suppose it will get slower if i put i set it too high. Won't make bit change anyway... prefer no latency !
And that actually CHANGES everything !!!! Even with Cubase monitoring the latency is gone (cannot feel it, at least hehe)
