  1. i didn't find a OM-library-solution for this kind of thing, so i coded it... if you want to REPLACE the articulation of some specific pitches. perhaps all 'd4 sould be PONTE... you could use this. it was necessary to code it like that, because otherwise you get in trouble with the empty parameter-slots... should work fine greetings andré ;;; SUBFUNCTIONS (defun eliminate-nil (alist) (loop for i in alist when (not (null i)) collect i)) (defun complete-event-slots (omn-list) (let ((omn-art (omn :articulation (single-events (flatten
  2. okay, but the "evaluation"-process (perhaps transpose note 2 octaves down and add pitch in a disctance of a fourth) must/could be done in LISP!?
  3. hi all does anybody already coded a FUNCTION to replace string-pitches by natural or artificial harmonics? is the specific notehead in OM (for the artificials)? would/could be very practical... perhaps if you have fast phrases in a large ambitus... the function - if it would be very well coded - could search for the nearest/closest fingering... greetings andré
  4. yes, i know - i love to code a lot of things myself, and at the moment i'm not very virtuous in it. but I have found a solution - without rebuilding my big programs. with (pprint-last-score) i can read and save the OMN, after evaluating and exporting xml/midi. so you were right, janusz, the solution was in the SYSTEM FUNCTIONS thanx for help - torsten, stéphane & janusz
  5. thank you, torsten - the problem is, that i'm working with my own random/pick-functions which don't work with SEED - so, that's my fault/problem
  6. hi all is there a possibility to SAVE my output - the OMN-lists - (rnd-generated structures) in a seperate file? that by EVALUATION the OMN-lists will be written in a sepeart/new-generated file? ...so that i have not to re-import it via MIDI (makes a lot of strange rhythms) thanks for help andré
  7. very interested in version 2.0 - features/release?
  8. hi brian, i modified shortly the code, now you could do what you want... "step-to-pitch" will test now what the tonality-input is ... if tonality = pitches -> then use this scale, othwerwise -> "expand the scale" (defun map-infinity-series (&key seq start tonality) (step-to-pitch :steps (integer-to-interval (reset-seq seq)) :pitches (if (pitchp (car tonality)) tonality (multiple-expand-tonality :startpitch 'c0 :octaves 7
  9. janusz, is this possible directly via "infinity-series"? greetings andré
  10. violà... bit more organized... a) now you could copy the SUBFUNCTIONS+MAINFUNCTION into: extensions -> user library. in that way all the functions will be loaded automatically, and it is not necessary to EVALUATE them before using... but it's useful to document it... b) otherwise... all this functions in your workspace/opmo-file... (like you are donig it wright now) ;;; SUBFUNCTIONS ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (defun step-to-pitch (&key steps pitches start) (let ((pos (car (position-ite
  11. i will write you a "merged"-function, takes not a lot of time, then it looks smarter :-) do you know how to use USER LIBRARY? very usefull - take a look... then you could import and use it like an ordinary OPMO-function
  12. is this correct? i think it is - not smart-coded but it works - you could merge the functions into ONE (sorry for my english). perhaps there is an OPMO-library-solution, but i don't know it... greetings (defun step-to-pitch (&key steps pitches start) (let ((pos (car (position-item start pitches)))) (append (list (nth pos pitches)) (loop for i in steps ;; setting pos by add the step to pos do (setf pos (+ pos i)) ;; when pitch-range to small then reset to lowest pitch+step ;; could be a more int
  13. but YOUR steps are not the same from the web-archive-example -> in the web-example it's from G in C-major, steps are -> 1 -2 -> YOU are starting with steps -> 0 1 -1 2 ... ??? but, i have no idea about this infinity-things, i only MAP your SEQ to MAJOR-scale... in the way you asked for (i think), so perhaps you have to rethink the MAIN-thing? best wishes andré added 6 minutes later you have to think different - these are NOT steps, these is a INTEGER-TO-PITCH thing... perhaps mixed with tonality-map -
  14. dear brian your pitch-range is too small for the step-sum... if you want to use it you have to enlarge your pitch-range. i've now done a small change - so you don' t have an error -> step-stack will now be set to 0, if pitches are lower or higher then your pitch-range, but in this case you don't have exact results mapping the STEPS so, enlarge your pitch-range -> perhaps with my "multiple-expand..."-function -> EXAMPLE 2 (defun step-to-pitch (&key steps pitches start) (let ((pos (car (position-item start pitches)))) (append (list (nth pos pit
  15. here are some solutions: user- or OPMO-defined greetings andré
  16. evaluate this, and check out the midi-destinations-function -> shows you the ports (midi-destinations)
  17. But in this way: (setf binrow '(0 2 5 7 8 11)) (gen-binary-row 12 '(binrow)) What am I missing ? just do it like that: (setf binrow '(0 2 5 7 8 11)) (gen-binary-row 12 binrow) ;; your "binrow" is now a variable with a LIST as value ;; when you are writing '(binrow) it will be a LIST with the VALUE binrow (and not the values of "binrow")
  18. really great, torsten! thanks a lot!!! greetings andré
  19. something like this? don't know if it's like this... you want to project a chord on these "filtered pitches"? (setf lengths '(1/2 1/16 7/16 1/8 3/8 3/16 5/16 1/4 1/4 5/16 3/16)) (setf pitches '(g5 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 fs4 a4 g4 gs4 a4 fs4 e4 b4 g4 gs4 fs4 a4 gs4 g4 f4 bb4 a4 fs4 e4 b4 fs4 a4 g4 gs4 e4 b4 a4 fs4 b4 e4 d4 cs5 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a
  20. like that? (setf lengths '(1/2 1/16 7/16 1/8 3/8 3/16 5/16 1/4 1/4 5/16 3/16)) (setf pitches '(g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 fs4 a4 g4 gs4 a4 fs4 e4 b4 g4 gs4 fs4 a4 gs4 g4 f4 bb4 a4 fs4 e4 b4 fs4 a4 g4 gs4 e4 b4 a4 fs4 b4 e4 d4 cs5 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 f4 bb4 gs4 g4)) ;;; get the pitches (loop for i in (append (list
  21. would be also interesting for me/my work! greetings andré
  22. i would only need the "FUNCTION" who starts the midi-play and the function which EVALUATEs (quasi the function behind the short-cuts) thanx
  23. question (from a non-programmer): is there a possibility (a way) to evaluate and/or start-to-play with a delay (of x-seconds) in opusmodus/lisp? would be interesting in the context of using POLYTEMPO NETWORK http://polytempo.zhdk.ch (virtual conductor) and LIVE-evaluation/play of an algorithm (and playing it live by an e-player) on/with a specific (delay-)time. could be something like: "do evaluate algorithm" "do play it in 21.543 seconds" any ideas or solutions? thanx for help andré
