your code would be very interesting

here is a pure LISP/CCL solution (loop for i from 1 to 100 collect (list (1+ (random 2)) i)) => ((1 1) (2 2) (2 3) (2 4) (1 5) (1 6) (1 7) (2 8) (1 9) (1 10) (1 11) (1 12) (2 13) (2 14) (1 15) (2 16) (2 17) (2 18) (2 19) (2 20) (1 21) (2 22) (2 23) (1 24) (2 25) (2 26) (1 27) (2 28) (2 29) (2 30) (2 31) (2 32) (2 33) (1 34) (2 35) (2 36) (1 37) (1 38) (2 39) (1 40) (1 41) (1 42) (1 43) (2 44) (2 45) (2 46) (2 47) (1 48) (2 49) (1 50) (2 51) (1 52) (2 53) (1 54) (1 55) (1 56) (2 57) (2 58) (1 59) (2 60) (1 61) (1 62) (1 63) (2 64) (1 65) (1 66) (2 67) (1 68) (1 69) (2 70) (2 71) (2 72) (1 73) (1 74) (2 75) (1 76) (1 77) (2 78) (2 79) (1 80) (2 81) (2 82) (1 83) (2 84) (2 85) (1 86) (1 87) (2 88) (2 89) (1 90) (2 91) (1 92) (1 93) (1 94) (2 95) (2 96) (2 97) (1 98) (1 99) (2 100)) as a function (defun pairs (n) (loop for i from 1 to n collect (list (1+ (random 2)) i))) (pairs 200)

if you are interested, i could show you some SOFTWARE to calculate really special tempo curves, in a very handy way. just write me a PM....

step by step => every code-line for itself cmd-E! i have also some LATENCY with conTimbre-player... but that's LISP in realtime the score player wasn't even intended to play things in parallel (i made a HACK from a HACK :-)). for precise POLYTEMPO things it is best to work via OSC and an external PLAYER (that's how I do it). I only need it in OPMO for sketching

i am very thankful for the HACK. lisp is not a language for real-time things, but for me it suits the approximate simulation perfectly!! thanx janusz!! but: you can try out how it is not to evaluate everything at once, step by step, maybe then there will be less LATENCY?

unfortunately i have no experience with DAW + polytempo... i always needed it for live-instrumental music

thanx, stephane! you are my OPMO-function-MASTER!

you will have the same DURATION when the pitch-loop and tempo-loop (tempo-progression = TIME) have the same length. so you have to stop the pitch-seq at the end of your BAR/tempo-seq!!! process should equal !? (gen-integer 110 60) (gen-integer 61 111)

great function, stephane!! little extension/different mapping ;;; a slightly extended version of stephane's FUNCTION ;;; with integer-output so you could map it on pitchfields/chords (defun pitch-trajectory* (nbpitch range tendency &key (variance 0.5) (type :around) (quantize 1/2) (smooth 1) filter-repeat seed (output 'int) (int-range '(0 24)) ) (setf seed (rnd-seed seed)) (do-verbose ("pitch-trajectory :seed ~s" seed) (let* ((values (gen-tendency nbpitch tendency :variance variance :type type :seed (seed))) (smoothedval (vector-smooth smooth values)) (out (cond ((equal output 'pitch) (vector-to-pitch range smoothedval :quantize quantize)) ((equal output 'int) (vector-round (car int-range) (cadr int-range) smoothedval))))) (if filter-repeat (filter-repeat filter-repeat out) out)))) ;;; pitch-ouput like in stephane's version (pitch-list-plot (pitch-trajectory* 128 '(fs3 g5) '(0.1 1 0.1) :filter-repeat 1 :variance 0.8 :output 'pitch )) ;;; integer-output for MAPPING (list-plot (pitch-trajectory* 128 '(fs3 g5) '(0.1 1 0.1) :filter-repeat 1 :variance 0.8 :output 'int :int-range '(0 23) )) ;;; MAPPING the integers on a scale or pitchfield (loop for i in (pitch-trajectory* 128 '(fs3 g5) '(0.1 1 0.1) :filter-repeat 1 :variance 0.8 :output 'int :int-range '(0 23)) with scale = (make-scale 'c2 24 :alt '(1 2)) collect (nth i scale)) (loop for i in (pitch-trajectory* 128 '(fs3 g5) '(0.1 3 0.1) :filter-repeat 1 :variance 0.9 :output 'int :int-range '(0 23)) with scale = (make-scale 'c2 24 :alt '(2 1 6 5 4)) collect (nth i scale)) ;;; an example with MAPPING and SAMPLING (progn (setf seq (loop for i in (pitch-trajectory* 64 '(fs3 g5) '(0.1 3 0.1) :filter-repeat 1 :variance 0.4 :output 'int :int-range '(0 23)) with scale = (make-scale 'c2 24 :alt '(2 1 6 5 4)) collect (nth i scale))) (make-omn :pitch (loop repeat 20 collect (rnd-sample-seq (rnd-pick '(11 17 29)) seq)) :length (pick-norepeat 20 '(t t. s -t. -t)) :span :pitch))

great, that it works fine now! greetings andré

it would be very interesting to work with that! also with the "chromatische Temposkala" by Stockhausen ...as EXTENSION for all your row/serialism-functions

i like to simulate parts with individual tempo curves (each instrument has its own tempo progession) and calculated "meeting-points". for that you will need INTEGERS. i wrote some pieces with with tempopolyphonic approaches - but i would like to simulate it with OPMO --- the software for REALTIME-conducting (PolytempoNetwork) and PolytempoComposer is here: https://polytempo.zhdk.ch PolytempoComposer: "The application PolytempoComposer allows to explore, sketch and organise complex tempo structures. It is a tool to calculate the exact time of every beat in a constant or variable tempo. Furthermore, it enables composers to find or adjust synchronisation points between voices in different tempos. Due to the graphical user interface, composers can manipulate the parameters of a complex tempo polyphony without any in-depth mathematical knowledge." --- in this video (was for something else: i'm sending new tempo curves data from OPMO to the conductingAPP (still without sheet music - only the conducting)) you can see how to manipulate tempo curves so that the end of the phrase is always at second 15. and how to reach a meeting point (e.g. T2 on 1) within the tempo curve at a different point in time. this can be calculated using the POLYTEMPO-COMPOSER app, output/saved as lisp format and then imported and conducted (by the APP). I would like to hear that and simulate it in advance on OPMO. I've already programmed it appropriately (to generate a SCORE with these tempo curves), but the ERROR is always because of float tempos. without float you won't create any usable polytempo structures on OPMO. if you round, the timepoints are of course no longer correct.

dear opmo it would be extremely helpful and useful if possible to enter the tempo as FLOAT as well. is there any possibility? thanx andré
