i downloaded mma and got it to work. it creates midi files from a set of changes. i'm trying to play these files with a variety of progams and none work. how do i know what, if any, midi hardware is in my machine? there is a /dev/sequencer on my machine: [dsevans@lindel] /home/dsevans/playmidi-2.4# ls -l /dev/sequencer crw------- 1 dsevans root 14, 1 Aug 30 2001 /dev/sequencer thanks dave
