I am playing with a MIDI dataset from https://www.reddit.com/r/WeAreTheMusicMakers/comments/3ajwe4/the_largest_midi_collection_on_the_internet
There are quite a bunch of files that have a following Channel Prefix meta message: 0xFF 0x20 0x01 0x10
As I understood from the specs, the last byte (the channel number) must be from 0x00 to 0x0F.
Is the value 0x10 valid, and if it is, what does it mean?
Windows Media Player does not see any problems with those files...
Your help will be appreciated!
