Custom MIDI Events Existing in the Output MIDI File
I am developing a program that handles midi files.
Most types of MIDI events have been dealt with, but MIDI files output from musescore are having difficulties due to custom events.
For example, a MIDI event of type 255 is interpreted as a track name (string) with a metatype of 3, and tempo (integer) with a metatype of 81.
However, in the file output from musescore, there are events of type 255 and metatype 127. If I treat it as an integer or string and read it, I get a very strange value.
Is there any public information about these custom events? Or is it a trade secret from musescore?
Thank you in advance!
