cozyMIDI - new app that plays std midi files (68k)

cozyMIDI:​

my brand new 68k mac application coded in C (and sweat). Plays standard MIDI files assuming you have an external module plugged on the modem port.

• loads and plays type 0 (1 track) and type 1 (more than 1 track) standard MIDI files
• keeps them in a pre-calculated form so the loop doesn't have to do real time divisions at the cost of slightly longer file opening delays
• animations with small graphic zones using CopyBits and 32 pixel width to keep it lean different MIDI instrument out of the 128 regular general MIDI instruments

  The bad formatter character for printf was a stupid mistake that I do occasionally.
  The real mistake was not setting up the .AIn driver properly with the clock like I did for .AOut. There was no chance of getting anything other than garbage before this was done. Once this was fixed with the printf statement, I saw the...
