thanks a lot for those compliments. One odd thing about Holst's score is the use of the pipe organ. He just threw it in, I think possibly because it was part of the concert hall where the piece was premiered. It is not too audible, since everything else is so loud.
Someone asked on another thread why do this? I would say first of all (besides it being a job) is that it is the best score study you could ever do. In fact, doing a midi rendition is much more intense study than copying by hand a score. I would never do this kind of work on a piece I didn't really admire. Also, I remember Jay Bacal saying it was a great way to play music. In other words, for the fun of performing music, though in a new way. Or is that distorting what you said Jay? I do notice that when the music begins to come together, there is a magical quality to it. you can hear the music coming into being. The silent score leaps into sound. Though it is great to get live performances also, that feeling you can get in midi, of music being born right in front of you, you don't quite get any other way.
