I think it is very worthwhile not to simply use complex functions, but to learn the basics/language of LISP. And then or in addition to that, try to program functions (in LISP/OM) yourself, to find ways of formalizing your ideas and needs. currently I am doing the same in/with MaxMSP

a little snippet of my work - including some sorting algorithms / hidden data / brownian bridges. played by Nenad Markovic (Ensemble Phoenix) - live recording. https://opusmodus.com/forums/topic/1039-sorting-algorithms/#comment-3314 https://opusmodus.com/forums/topic/2958-brownian-bridge/#comment-10267

a quick idea: if you would do it with rnd-walk and use it as positions in a pitchfield, you have a some global control over all parameters. pitchfields are - in my opinion - useful, because you have some nice vertical control. you don't have this if you simply have the random walk out of the pitches directly. (progn ;; do a rnd-walk with tendency (setf walk (gen-walk 24 :step '(1 2 3) :backward 0.3 :forward 0.7)) ;; transform it to positions in a pitchfield and "reset list" if min-val < 0 (setf positions (cumulative-sums walk)) (setf positions (if (< (find-min positions) 0) (x+b positions (abs (find-min positions))) positions)) ;; define a pitchfield (or chord) (setf pitchfield (append (expand-tonality '(b3 messiaen-mode6)) (expand-tonality '(b4 messiaen-mode5)) (expand-tonality '(b5 messiaen-mode4)) (expand-tonality '(b6 messiaen-mode3)))) ;; reading pitchfield by positions (position-filter (cumulative-sums walk) pitchfield))

very nice, like a SIEVE!! if it would be like: (rnd-rest '(8 7 6 5 4 3 2 1) omn-seq) you could manage the event-density in time... or... (rnd-rest '(0.1 0.2 0.23 0.4 0.7 0.6 0.3 0.43 0.91) omn-seq) ...perhaps also with (gen-envelope-tendency) (or something like that just a spontanious idea

funny but of course it is far far away from bach or a choral harmonization I think there are various difficulties, on the one hand whether chatGPT finds enough information on the net about the harmonization of chorales and probably far too little about OPUSMODUS and LISP. chatGPT doesn't really manage to program usefully in LISP (e.g. I tested sorting algorithms), but chatGPT explained to me extensively how the resulting code works, but it was always full of errorr/bugs. never worked, not fixable either. there is simply still a large amount of data missing for the system. But of course I'm not a specialist, I just tried it (chatGPT) out in an amateurish way

thanx! this software is such a great tool!!!

was it not like...? (rnd-sample-seq 2 '(1 2 3 4 5)) => (1 2) => (3 4) (rnd-sample-seq 3 '(1 2 3 4 5)) => (2 3 4) => (3 4 5)

what is the new name of the function "rnd-sample-seq" thanx for a quick help! andré
