but large parts are rewritten by matk and tanimura. This is old code, it's not maintained since 2003. We also don't have a maintainer for this! Yuriy Tsibizov took it and uses it in his emu10kx driver. Since the emu10kx driver will enter the tree "soon" (some bugs have to be fixed after Yuriy return from his holidays), I add it here already. This also contains some changes to emu10k1 and cmi, so if you're lucky, you can now make some kind of use of midi with those soundcards. To all those poor souls which don't have such a card: feel free to send patches, we don't have a maintainer for this. To those which miss a specific feature in the midi code: feel free to submit patches, we don't have a maintainer for this. Oh, did I already told that it would be nice if someone would take care of it? Maintainer with midi equipment wanted! :-) If you get LOR's, submit a PR and notify multimedia@ please. If you get panics, submit a PR with a backtrace (compile the sound system into your kernel instead of using modules in this case) and notify multimedia@ please. Written by: matk, tanimura Submitted by: "Yuriy Tsibizov" <Yuriy.Tsibizov@gfk.ru> Based upon: code from NetBSD
