hi Cosmo, I will explain a few things quickly, that might help your understanding a little. OSS - is the old sound drivers for linux ALSA - is the newer implementation, and default linux-audio drivers. Jack - is the low-latency driver. It is cross-platform. On linux, you will either run OSS or ALSA as Jack's backend. While on a Mac, you would use "core audio" for the backend. So that being said, You will still require ALSA for jack to work. As ALSA is communicating with your hardware and provides alsa-midi, as well. Jack is like ASIO and REWIRE in windows. (sort of) it also can provide midi As far as sound quality goes, you will want to use 44100, as that is CD quality. 22100 is fairly low-quality, don't use that. there is your answer! As far as recommended reading, there is a ton of it. First, i would ask what Linux Distro do you use? what are you trying to accomplish, ie: a DAW, or a "live type environment", etc. If you can get back to me on this, however, this strays big-time from the wine-dev list, so i would ask you to just send ME a message, rather than having it posted on this list. But yes, i will take a look through my bookmarks, i am sure there is some goodies in there for you. get back to me, and i will have a look. jordan
