For what it's worth... I do a lot of exactly this: aleatoric composition in Lilypond. My "seven pieces for seunge hye", which is somewhere on www.apollinemike.com/mike, uses this in pieces 1, 4, and 6. My most recent piece, "Norman (12 ans) à la dernière répétition avant sa Bar Mitzvah", also does a fair bit of this: it is not posted online, but I'd be happy to share the code with you if you'd like.
I use Python for all of my aleatory and have Python spit out lilypond-parseable code. There is no good reason for this aside from the fact that, for me, thinking creatively in Python is easier and faster than thinking creatively in Scheme. I have also learned that everything I want to do in Python is, with elbow grease, possible somehow in Scheme (to date). My rule of thumb is that I only write in Scheme when it comes to lilypond development, and I only do lilypond development when I want to help others or create a new feature, and I only do the latter when there is truly truly no other way of making it happen in lilypond without writing something new AND I have time AND I am confident that I will use it in more than one piece AND I am confident that others will use it as well. Everything else is done in Python because Python rocks. ~Mike On 7/20/10 6:17 PM, "Martin Tarenskeen" <m.tarensk...@zonnet.nl> wrote: > Hi, > > I'm thinking of writing a little fun application based on "Mozart's > Musikalisches Wuerfelspiel".
