    maxmsp and lisp?

    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
  4. dear all conTimbre-library works (in the next update) perfect with TUNING (midi-pitchbend) and PAN now. thanx to thomas hummel and janusz! here are some simple sound examples... ct-micro+pan2.aiff ct-micro+pan3.aiff ct-micro+pan.aiff ct-micro+pan4.aiff
  5. "then there is a bug in conTimbre midi listener"... okay i will tell thomas hummel thanks
  6. dear all is there a possibility to change the PAN in every EVENT? 1) like '((q c4 mp pan-30) (e c3 pp pan100)) would be interesting for LIVE-CODING is there something predifined? like it will come up with microtonality/tuning 2) and why does it work with simple-midi-sound (a list in :pan) and not with a player like conTimbre (there is something i don't understand with midi/players/etc)? thanx for a hint andré an example: (setf omn '((5q c4 5q 5q 5q 5q 5q 5q 5q) (-q) (e e e e e) (-q) (7q 7q) (3q 3q) (-q) (5q 5q 5q) (7q 7q) (3q 3q 3q 3q) (e e) (-q) (3q 3q 3q 3q 3q) (e e e e e))) ;;; (def-score signature (:title "signature" :key-signature 'atonal :time-signature '(4 4) :tempo 60) (instr ;:port 0 :omn (omn-replace :velocity (pick-norepeat 100 '(pppp ppppp ppp ppp pp p)) (length-diminution 4 (gen-repeat 10 omn))) :tuning (gen-white-noise 100 :scale 0.1) :pan '(1 1 1 1 1 1 1 1 10 30 1 1 1 100 100 80 77 15 100 100 100) :channel 1 :sound 'gm-trumpet))
  7. I got a trial version of the new conTimbre-player-maxpatch (from thomas hummel), now the opusmodus-tuning also works well in conTimbre. I think it will be in the next update ... ...i like it more in cents then in float... (defun cents-to-tuning (centlist) (a*x 0.01 centlist)) (cents-to-tuning '(-14 +50 5)) => (-0.14 0.5 0.049999997)

  9. i already did that (defun add-rnd-dust (omnseq &key (span '(0.1)) (seed nil) (quantize '(1 2 3 4 5 6 7 8 9)) (scale 1.0) (tolerance 0.05)) (let ((rhy (omn :length omnseq)) (sp)) (progn (setf rhy (loop with cnt = 0 for i in rhy do (setf sp (nth cnt span)) when (not (null seed)) do (incf seed) when (> i 0) collect (+ i (car (rnd-number 1 0.0 (* i sp) :seed seed))) else collect (- i (car (rnd-number 1 0.0 (* i sp) :seed seed))) when (< cnt (1- (length span))) do (incf cnt))) (make-omn :length (quantize (float-to-ratio rhy :ratio 1/1) quantize :scale scale :tolerance tolerance) :pitch (omn :pitch omnseq) :velocity (omn :velocity omnseq) :articulation (omn :articulation omnseq)))))
  10. an example: this is the BASIC-version (without "dust"): all mapped in 1/32 - retrograde sorting processes (with GEN-SORT): pitch-process from chromatic to 12tone-row (by sort) and from sorted length-values (all 1/32, then all 1/16 etc... to more complex/mixed pattern (by sort)) with this setup: the result with some "dust": if you you have a look to the span-list above (compare with the new score) you will see: no change at the beginning, then more and more randomized (or made flexible).
  11. @janusz: if you try the function a few times (without seed) , you will see (by cmd1), that sometimes the last TIE isn't there. i think QUANTIZE is doing this little bug... (but perhaps only a xml-display-thing?)

    maxmsp and lisp?

    the only problem seems to be, that it only works with CCL 1.12 on mojave... but this is not the official actual version in apple's appstore. so it don't work with 1.11.... does anyone know how to fix this problem?

    maxmsp and lisp?

    dear all does anyone have experience with an implementation of LISP in maxmsp? i'm looking for: "Max handling real time input, output, timing and control, letting Lisp handle variable handling and of course the processing of large amounts of data" does anyone tested this? https://github.com/thealexgraham/lisper/blob/master/README.md https://cycling74.com thanx for a hint andré

  19. you should also share your ideas/thoughts/concepts!!??
  20. hi julio it's too complicated to share the code...the FUNCTION is made for a specific idea of the work (not common), so it's made for MY need... here is a short sketch of the work... (part of it) a) generating a pitch-sequence => by using a 12-tone-seq + its expansion by a sorting-algorithm (with GEN-SORT) => an INTERVAL-order mutates to a SCALE (see the list-plot) b) pitches are projected on a sequence of symmetrical expanding/compressing FIELDS (with CHORD-CONTR...) => you see how the pitch-seq is contracted/exapnded in "space" - result is a kind of interference of this processes => at the end you see (in list-plot) that the interference is going more and more to ONE LEVEL - to a SCALE - so its a kind of inside/out. the inherent structure, the inherent process/order is more and more recognizable during the process (start with compr/exp. 12-tone-row to the simple SCALE) the project is a bit larger. this sequence (which rhythm is based on a binary-event-filter (data of a jpeg of an artist)) is only the structural background (some ideas developed by LACHENMANN) - on this NET (the score you see) there will be other GESTALTS/MOTIFS etc... because my needs are such specific to my and my idea - most of the functions i had to code for myself, or modify/enlarge the OPMO functions, great that this is possible on this platform. sorry a bit complicated and i can't not describe it properly with a few words
  21. BUG is fixed now. should work correct!
