I have some .TD9 files which are recordings from the Roland TD-9 Drum Computer.
Anyone has any idea how these files are structured ?
Are they anything like MIDI ?
Or maybe they have MIDI data wrapped inside the file ?
I tried making several files to be able to draw some conclusions from comparing them,
but even a recording from just one hit has so much unique data in it, that I wondering what the purpose of all that information could be.
I suspected it would be not much more than a timestamp, a note value and a value for the velocity ?
How many bytes is a timestamp for MIDI ?
Any help to figure out the grammar of a TD9's .seq file would be greatly appreciated
