Ok, the file has already been online for a week, but I waited, following the rules of this forum, so as not to have more than one topic on page 1 of the listening room.
Last week I reworked a MIDI file which I created 15 years ago - one of my very first sequences I had created. Found several errors; took me 13 hours to get the first version in GPO4 running. And posted next day a revision.
I am talking about Antonin Dvorak's Largo (2nd movement) from his Symphony No.9, "From the New World".
Listen to the newest version on that page.
