I tried saving a song to MIDI but I do not see any option to have "Chord Output enabled".
Look closer, this option is in the "options menu". It is tricky as the midi file is saved somewhere/somehow. I got it written down somewhere. I use this with EZKeys.
Looked close lots of times. No "Chord Output" option that I can find.
Maybe I am doing it wrong? Here is what I am doing...
1) load song
2) click the .MID button located in the File section of the toolbar
3) from the popup I click Options button
4) the options window that pops up is "MIDI file options" but it has no "Chord Output" setting
5) click OK then click File on Disk button
