Ok so I've read through some threads and I'm still confused. One thread gave me the impression that the M-Audio-USB was ASIO. I did download ASIO4all. When I chose ASIO the only thing that is available is my SoundMax digital audio. The only place the M-Audio shows up is in WaveOut. I can set the first buffer number to 3 and get down to 69ms but the quality doesn't seem as good would that be correct or are my ears deceiving me? Plus 69ms is still to much for comfort anyway. Should I be looking at the Audio buffering settings? The M-audio is not mine I'm just borrowing for Reaper testing. I'm going to get something I can record multiple channels with but I'd like to know a little more about what I'm doing before I go there. Also My computer is about 6 years old Dell 2400 2.66ghz 768ram (I know I need to upgrade that - I'm thinking replacing the 256 with a 1G making 1.5G should be enough?) any help much appreciated !! Thanks, Den
