This program (mkmid) is the MIDI data converter from key notes text file. (2006/11/19 version) The usage of this program is mkmid music.txt (music.txt is key notes text file). In the mid of executing program, output.trk and output.dat are made for pre-processing, but these files are not used in the playing midi file. So you can delete output.trk and output.dat. In this version, (1) TEMPO (2) KEY CODE (till 32 tracks) are selected. Perhaps you can understand the format of key notes text file with sample file(sample.txt). You can change the tempo of music as followings. (You cannot select sound effects like vibration and chorus in this version.)

I am happy when you can understand the format of key notes text file with sample file (sample.txt). Thanks, Toru Okumura(toru@okunet.gr.jp)
