it's not necessary for me, just an idea 😉

;;; a little extension for lsystems, i needed all generations, not only the final one. i think for in-time-processes it's more interesting, because you will hear/see the way of "growing/developing" ;;; perhaps JANUSZ could extended the original OPMO-function. keep attention about stack-overflow if you have LARGE DEPth :-) ;;; function (defun all-gen-lsystem (ls &key depth ) (loop repeat (1+ depth) for i from 0 to depth collect (rewrite-lsystem ls :depth i))) ;;; setup (defclass sieve_1 (l-system) ((axiom :initform '(1)) (depth :initform 10))) (defmethod l-productions ((ls sieve_1)) (choose-production ls (1 (--> 2 1)) (2 (--> 4)) (4 (--> 2 6)) (6 (--> 1)))) ;;; example ; new => all gen (all-gen-lsystem 'sieve_1 :depth 3) => ((1) (2 1) (4 2 1) (2 6 4 2 1)) ; original => only last gen (rewrite-lsystem 'sieve_1 :depth 3) => (2 6 4 2 1)

because in such a fast "basic tempo" they were too close to "17" and "23" 😉 i think in slower tempo it makes sense to work with numbers they are close/closer to each other. then the perception compares the tempi, when the GAPS are to large it's only "SLOW/FAST".... depends on your ideas... THANKS FOR THE HINT, i will look at it!! andré

polytemporal fall - algorithmic study [with tempo relations 3:5:7:11:17:23:29] this is a small example: i coordinate and play MIDIs (in this case this are simple scales) in OPMO via OSC -> maxmsp_player. you can here how precise you can coordinate simple [but polytemporal] scales => all the MIDIs coincide (?) - 30000ms after the evaluation of the code - in an unsiono pitch!!! in that way you can coordinate different scores/midi's (which have individual tempos (!)) very precise. with OSC/maxmsp_player you can change/manipulate the tempi of the midi's (directly from OPMO) so you can be variable with pre-produced midis (perhaps produced in OPMO)... greetings a.

"What you are doing Andre is quite bad and unsafe" very friendly, your answer 🤨 ...and i knew that, but i didn't found some hints (jn the tutorials) how to extract OMN from def-score. of course it is not good, but it took me only 2 minutes to briefly the problem for my specific application. i have not written any official opusmodus-function (which can do anything) but a simple solution which helps me.

oh, this was simple 🙂 here is a small program, it works... (defun get-pitch-from-midi (midipath) (loop for i in (flatten (compile-score (midi-to-score midipath) :output :score)) when (or (chordp i) (pitchp i)) collect i)) (get-pitch-from-midi "path/filename") also with length?! (defun get-length-from-midi (midipath) (loop for i in (flatten (compile-score (midi-to-score midipath) :output :score)) when (and (lengthp i) (not (integerp i))) collect i)) (get-length-from-midi "path/filename") but will not work with more then one voice / its not necessary for MY needs, so i coded only this simple solution - perhaps janusz will do it?

for me usage it has to be "by OSC". i have to be able to control two programs (conducting/display + e-player/samples) simultaneously and in a coordinated way. so i can send DATA for both software-applications well coordinated...

dear all here is a setup for playing midi-files/scores in polytempi / follow the instructions and have fun! just ask if you have some questions... greetings andré - personally i will use it for exact sample/e-player perfomance with my pieces which are working with "Technology-Assisted Conducting" http://polytempo.zhdk.ch ... in future i will do it all directly from OPMO or lisp - "live score generating" + polytempo-conducting + e-player) - i have already done this with my piece MODULAR FORM but not all controlled by LISP/OPMO, so next step is doing it all in OPMO/LISP greetings andré https://en.wikipedia.org/wiki/Polytempo/ ;;; POLYTEMPO-PLAY ;;; with a MAX-patch (from my friend thomas peter) and some OSC-send i can play the same/different midis (up to 30) ;;; in different tempos in parallel - any combination, with precise coordination ;;; also possible: change global velocity (means: change velocity inside midi) ;;; time-delay (start) in ms ;;; 1) OSC-send functions: (defparameter *out-socket* (make-socket :type :datagram)) (defparameter *remote-host* "127.0.0.1") (defparameter *remote-port* 7500) (defun udpsend (&rest args) (let ((message (apply' osc::encode-message args))) (send-to *out-socket* message (length message) :remote-host *remote-host* :remote-port *remote-port*))) ;;; 2) a) put the MAX-player-folder on desktop ;;; b) start midiplayer.maxpat ;;; c) midiplayer: define your output source in [midiout@name "from MAX 1"] ;;; d) the MIDIS must be placed in the midi-folder (inside MAX-player-folder) ;;; 3) generate SCORE (here a nonsense example) (setf omn (make-omn :pitch (setf pitches (filter-repeat 1 (flatten (gen-sort (rnd-air :type :pitch :seed 45) :step 5 :sort '> :seed 123)))) :length (gen-length '(1) 1/32) :velocity (pitch-to-velocity 'p 'mf pitches :type :float) :span :pitch)) (def-score sorted-whitenoise (:title "sorted-whitenoise" :key-signature 'atonal :time-signature '(4 4) :tempo 60 :layout (grand-layout 'inst)) (inst :omn omn :port 0 :channel 1 :sound 'gm :program 'acoustic-grand-piano)) ;;; 4) COMPILE that score into your Max-Player/midi-folder => PATH+NAME!!!

too much code and too complicated to post - I do not have the time to write a manual. it's a "machine" that creates multiple "brownian bridges" combined with "pitch-contour" and "add-rnd-dust". it's an all-in-ONE tool/machine/bot... I'm interested in repetition/difference in other contexts than traditional ones; but "brownian bridges" then resemble ornaments. when the sequences are short - brownian bridges are "rnd-processes" between 2 fixed points - then you will keep ornamental sequences between this 2 points/pitches... (I did not work with a score, just coding and listening - it's only sketching/testing, not composing. and all the examples are "rnd-generated"/not-composed by the machine, you could produce more and more...) some links: Brownian bridge - Wikipedia EN.WIKIPEDIA.ORG -> in OPMO

another example/experiment - you hear 4 times the same "brownian-phrase" but mapped on different tonalities... untitled.aiff a) diatonic/major b) blues-heptatonic c) chromatic d) messiaen-modus greetings andré

thanx, but just a project/coding sketch - nothing serious 😉

you could add it!
perhaps you have some better ideas - ...perhaps with range/ambitus... sometimes in trouble - but i only use it for my current work, and so it's no problem 🙂 could be nice if you could do the add-system also with an external list input -> not fibonacci or primes or sum, but perhaps also with any integer or float list. so MODIFY-function could be done with any DATA... and perhaps it could be also nice for LENGTH and DYNAMICS, i would like that (all-in-one)

yesterday we tried to implement/start maxlispj on MAX 8 http://sites.music.columbia.edu/brad/maxlispj/ maxlispj is from 2011, it works more or less in MAX 8 / MOJAVE, but not stable enough. perhaps there will a be some better solutiuons in the future... greetings andré
Clozure CL => the new COMMON LISP version works with MOJAVE now 🙂 have a look at apple's appstore
