To butchrichard. Thanks for the reply. The scenario I have though, is one whereby I like to use softsynths , pianos, instruments etc inside my DAW...The latency concern isn't so much FX because you can do as you described. I think 20 years ago, the idea of needing really low response time (latency) from software instruments that you may be playing as your tune progresses with audio tracks with added software effects wasn't as widespread as it is now. That's the need for really low latency. You want that keyboard or piano part to not feel slightly or severely delayed as your tracking or writing the part during playback of the project. And as I'm one guy, the quantum is kinda overkill in terms of INs/Outs for me. I think a lot of individual guys in my shoes have the same concerns...a reliable interface where I/O's is less of a concern than a natural feel to playing synths back inside the DAW software. I wonder if the new Presonus 6/8 has similar performance characteristics to the Studio 192...it's size is more suited to my situation and as I mentioned, it's that performance delay that is so crucial from an interface in this day and age for a home studio. Thanks.
