over the next few days ill be posting urls to some nice pieces that
students in my advanced algorithmic composition classes did this
semester and have given me permission to post. the projects are wide-
ranging -- many involve clm, some involve performers, some use
interactive disklavier, a quad csound piece for trumpet and tape,
kayageum and tape, etc! ill probably post 1 a day or so alphabetically
and will send a note when i add a new one

first up is alex bielen's Skyharp and Bristiling (grani, fullmix,
vkey, expandn etc)

Re: music projects

I like it! I noticed that expandn.ins wasn't in CLM (except an old version in the test suite), so I added it to the CLM tarball, and translated it to scheme (in clm-ins.scm).

Multipart in a "process"

Hi I try to generate multipart music (with different rhythmic values) within the same 'process', because all parts have to get their values serially from the same set. (defun cellular (mal) (process for i below mal for amp1 = (if (= (nth 0 (nth i set-1)) 0) 0 0.6) for key1 = (if (= am0 0.6) (nth (pop set-2) set-3) 124) for dur1 = (if (= (nth 0 (nth i set-4)) 1) (if (eq (set 'a (length (1leri-bul (pop set-5)))) 0) .5 (/ 0.5 a)) .5) for amp2 = .... for key2 = .... etc .. .. output (new midi ...: duration sprout (new midi .. .. wait) That "wait" clause determines all of the rhythmic values, although the ":duration"al values are different. To define different functions (as many as parts) and use as (events (list ..)); don't serve my purpose. How to settle this handicap? ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
