Sorry, this is probably a very newbie question, and I haven't lurked very long or searched the archives (partly because I don't have a good idea of keywords to search for). I've used Linux for a few years, but sound isn't normally a concern. My son is trying to make the switch from Windows to Linux (and has, for some things) and now wants to play midi files. His impression is that, on Windows, sound players use synthesizer's (and "patches"/"samples") built into the sound card while on Linux those patches/samples (??) have to be downloaded and he talks about 40 MB worth of files in some cases. Maybe the difference is that we also changed computers, and his current computer has an on-board SiS 7018 sound thingie while his previous computer (IIRC) had a separate sound card, possibly with something like the Yamaha OPL xxx on it. Any light anybody can shed on this would be appreciated. (I did skim through a Linux Sound HOWTO (that was actually a little bit more like an FAQ), and saw some hints, but I really don't know how to interpret them.) Keywords to use to search the archives or Google, or pointers to simple documentation that focuses on this subject could also be helpful. No doubt what ever I learn will end up on a WikiLearn page (http://twiki.org/cgi-bin/view/Wikilearn/WebChanges). thanks, Randy Kramer
