I don't know of any freeware off the top of my head that'll do what you want, though I'm sure it's out there. Basically *any* good notation software will import midi's and let you view the tracks and notations.

Personally I use Finale 2002 for notation stuff, which does a really good job when importing midi's, but it'd be a pretty expensive buy for just wanting to view a midi. (I think your cousin would help you with the funds, though.) Finale Notepad *is* free, but it doesn't import midi's.

Suckers like me use ModPlug ;_;

Isn't Cakewalk one of the best (i.e. most expensive) midi sequencers available? Also, there is Cubase.

3) TiMidity (I use this free program for playing M.I.D.I. music files; its Tracer panel is good for viewing the tracks, and TiMidity may display comments, lyrics, and so forth; it loads SoundFonts). My TiMidity configuration is as follows: I have all effects, tweaks, and special options turned off for a clean sound. My TiMidity configuration follows: all GM/GS/XG options but Insertion Effect Control checked; all special options unchecked; play parameter maximum voices set to 256, amplification set to 40%, antialiasing instrument checked, load instruments while playing unchecked, unload intsruments between files checked, auto reduction voice unchecked; default M.I.D.I. type clicked to G.S.; all musical grammar options unchecked; resample cache parameter set to 2097152, default tonebank parameter set to 0; all tonebank unchecked, control ratio parameter 0, trace playing checked, console verbosity parameter 2, drum power(%) parameter 100, amplitude compensation unchecked. 4) Papelmedia Premium version SoundFont is now selling for ~$55 including shipping. It is the General M.I.D.I., and General Synthesis SoundFont I use with M.I.D.I. music files. I have in use a two-gigahertz Pentium 4 that has one gigabyte R.A.M. installed.
