EDIT 2: Fix 1.4b - For those using midi_write_record_begin() there were timing issues with 1.4a, the following replacement DLL was created in 2010 upon request but I no longer have the source code. The DLL was compiled with Visual C++ rather than mingw like 1.4a.

This dll allows you to play midi files, individual midi notes, and to write midi files in format 0. It also allows simple recording where all midi note/command output (not file playing however) is written to a file. The midi input is limited and may be buggy, it is completely untested, as I am unable to. It uses the Windows functions rather than allegro functions so midi_init() is not required. I added the digmid capabilities to this dll after I discovered a way for it to work the way I intended; my other dll is therefore decrepit and useless unless you wish to use both at once.

*Updates V1.4*
-many bug fixes, and minor changes
-added a simple midi record and write mechanism ("midi_write_record_begin" "midi_write_record_end"); after it starts recording, all midi notes/commands played (other then playing midi files) are recorded, and then written to a midi file (This is much easier and completely automatic). The timing is probably 99% accurate.
-added basic midi input functions, they are are untested, and may need to be rewritten. They will definitely be improved after testing.
-MTrk_size was renamed midi_write_MTrk_size, and has an extra parameter, it is no longer written in gml but compiled.
-add more option for initialization
-add midi in/out device functions to get information
-digmid is now mostly supported in this dll, my other dll is decrepit and useless
-updated volume change functions to take 2 parameters each: digital volume, midi volume.
-add midi_return_cmd which returns the last standard (not meta or sysex) midi command executed
-removed non operational midi_note_edit and added midi_volume_edit
The source code is provided and anyone may use as they wish. If you really want to have an update/fix, I may consider it; just send an email to me. Another thing is that this dll will not be useful for all of the platforms that YoYogames "believes" it will port GM, unless gm thereof supports linking to static libraries (this would still need modifciation).
