There is a variable 'r inside your OMN — but what is it bound to? Within the OMN format, r doesn’t work as a proper length value; must be e replaced by a negative length value, otherwise you get an error...
=> (1/4 c4 pp stacc 1/8 r 1/8 c6 pp marc 1/16 d4 pp ten 1/4 cs4 pp stacc 1/8 c4 pp leg 1/8 b5 pp marc 1/16 eb4 pp ten 1/4 c6 pp stacc 1/8 r 1/8 r ...
When i replace the variable 'r by -1/4 it works...
=> (1/4 c4 pp stacc 1/8 -1/4 1/8 c6 pp marc 1/16 d4 pp ten 1/4 cs4 pp stacc 1/8 c4 pp leg 1/8 b5 pp marc 1/16 eb4 pp ten 1/4 c6 pp stacc 1/8 -1/4 1/8 -1/4 ...
(setf flute-omn (replace-map '((r -1/4)) (build-omn-with-rests flute-pitches flute-rhythms flute-velocities flute-articulations))Personally, I wouldn’t use the variable "p", beause in the system it’s used for “piano” (which is why it’s highlighted in red). Also, it’s probably clearer and easier not to generate the OMN using a LOOP, but instead to use "make-omn". That way, you can also replace specific variables (like your 'r) more easily/more organized.

The following function generates symmetrical structures based on sequences of tones, which can evolve over multiple generations, resulting in nested symmetries. Here are a few examples mapped to pitches, integers, and rhythms.
(defun gen-symmetrical-structure (&key row gen) (let* ((seq1 (filter-repeat 1 (loop repeat gen for i in (rnd-sample '(3 5 7 11) :norep t) append (progn (setf r1 (filter-first 11 row)) (setf r2 (filter-last 11 row)) (setf n i) (setf rev (probp 0.5)) (setf r1 (if (null rev) r1 (reverse r1))) (setf r2 (if (null rev) r2 (reverse r2))) (flatten (gen-rotate (random 2) (list (filter-first n r1) (filter-last n r2)))))))) (seq2 (flatten (gen-rotate (random 2) (list (filter-first (length seq1) seq1) (pitch-invert-start 'fs4 (reverse (filter-first (length seq1) seq1)))))))) (filter-repeat 1 (flatten seq2)))) ;; with one GEN (pitch-list-plot (gen-symmetrical-structure :row (rnd-air :type :pitch) :gen 1) :join-points t :style :fill) ;; with x GEN (pitch-list-plot (gen-symmetrical-structure :row (rnd-air :type :pitch) :gen (+ 2 (random 10))) :join-points t :style :fill) ;; remapped to integer (list-plot (pitch-to-integer (gen-symmetrical-structure :row (rnd-air :type :pitch) :gen (+ 2 (random 10)))) :join-points t :style :fill) => (9 5 7 1 10 11 4 8 3 2 0 6 9 5 7 1 10 11 4 8 3 2 0 2 3 8 4 1 7 5 9 6 0 2 3 8 4 11 10 11 10 1 7 5 9 6 3 7 5 11 2 1 2 1 8 4 9 10 12 6 3 7 5 11 8 4 9 10 12 10 9 4 8 1 2 11 5 7 3 6 12 10 9 4 8 1 2 11 5 7 3) ;; remapped to lengths (length-list-plot (gen-length (pitch-to-integer (gen-symmetrical-structure :row (rnd-air :type :pitch) :gen (+ 2 (random 10)))) '1/32) :join-points t :style :fill) => (11/32 3/32 9/32 5/16 3/8 3/16 1/16 7/32 5/32 1/8 1/16 7/32 5/32 1/8 1/32 1/4 11/32 3/32 9/32 5/16 3/8 3/16 1/16 7/32 5/32 1/8 1/32 1/4 11/32 3/32 9/32 5/16 1/16 3/32 9/32 1/32 1/8 11/32 1/4 7/32 5/32 5/16 3/16 -1/32 1/16 3/32 9/32 1/32 1/8 11/32 1/4 7/32 5/32 5/16 1/4 7/32 5/32 5/16 3/16 -1/32 1/16 3/32 9/32 1/32)

With the following functions, you can run a background process (e.g., a loop function that constantly reloads data, for example from a text file) and do other things in parallel, such as modifying functions, etc. This is helpful when working with LISP/Opusmodus to process data in real time. I’ve tested this for a few days now, and it seems to run well and stable — at least as stable as the background process functions are free of bugs.
Starting the process: Give the process a name and "add" your function (Here’s an example I made) -> process name “mididateien-generieren”, and my function within it is called “gen_1.midi”
(mp:process-run-function "mididateien-generieren" nil #'gen_1.midi)Stopping the background process
(progn (print "mididateien-generieren gestoppt") (mp:map-processes (lambda (proc) (when (string= (mp:process-name proc) "mididateien-generieren") (mp:process-kill proc)))))If anyone has better solutions for this, I’d be happy to hear them!

One more small (improved) function: a starting rhythm (pattern) gradually changes its values towards a constant pulse/value (endvalue).
Other possible applications: An initial pitch sequence evolves into a steady, constant pitch. A start pattern for velocity gradually shifts towards a fixed velocity.
(defun gen-acc/rit (alist endvalue) ;; startpattern + endvalue (loop while (not (equal alist (gen-repeat (length alist) endvalue))) collect (setf alist (loop for i in alist when (/= i endvalue) collect (if (> i endvalue) (- i 1) (+ i 1)) else collect i)))) (list-plot (flatten (gen-acc/rit '(1 7 4 2 11 9 5 3) 3)) :join-points t :style :fill) => ((2 6 3 3 10 8 4 3) (3 5 3 3 9 7 3 3) (3 4 3 3 8 6 3 3) (3 3 3 3 7 5 3 3) (3 3 3 3 6 4 3 3) (3 3 3 3 5 3 3 3) (3 3 3 3 4 3 3 3) (3 3 3 3 3 3 3 3)) (list-plot (flatten (gen-acc/rit '(1 7 4 2 11 9 5 3) 15)) :join-points t :style :fill) => ((2 8 5 3 12 10 6 4) (3 9 6 4 13 11 7 5) (4 10 7 5 14 12 8 6) (5 11 8 6 15 13 9 7) (6 12 9 7 15 14 10 8) (7 13 10 8 15 15 11 9) (8 14 11 9 15 15 12 10) (9 15 12 10 15 15 13 11) (10 15 13 11 15 15 14 12) (11 15 14 12 15 15 15 13) (12 15 15 13 15 15 15 14) (13 15 15 14 15 15 15 15) (14 15 15 15 15 15 15 15) (15 15 15 15 15 15 15 15)) (list-plot (flatten (gen-acc/rit '(1 2 3 1 5 7 11 3 13 ) 6)) :join-points t :style :fill) => (((4 6 2 6 2 12 3 4 10) (5 6 3 6 3 11 4 5 9) (6 6 4 6 4 10 5 6 8) (6 6 5 6 5 9 6 6 7) (6 6 6 6 6 8 6 6 6) (6 6 6 6 6 7 6 6 6) (6 6 6 6 6 6 6 6 6))

just one more really messy sketch: you could "re-import" the OPMO-generated score (via midi) to MaxMSP (bach.roll -> bach.score).the notes you see are coming from the right channel – just a bunch of random pitches… nothing serious, but it shows a possible idea

Real-Time Pitch Memory: Compositional Feedback System Using MaxMSP and OPUSMODUS
This text outlines a specific aspect of a larger project I am developing for live electronics and instruments. Since the work heavily involves live electronic processing in real time, it is based on a MaxMSP patch that I am currently building.
An important component of this system involves integrating OPUSMODUS for certain compositional processes—specifically, the processing of pitch material collected in real time via a pitch follower from an improvising musician.
In MaxMSP, this means that every few seconds, the most recently played pitches (as MIDI note numbers) are saved into a .txt file. Meanwhile, in OPUSMODUS, I run a routine that checks once per second whether a new pitch list has been saved (i.e., a list that differs from the previous one). If a new list is detected, I generate an OMN sequence based on this list and export it as a MIDI file.
Only ten MIDI files are generated and continuously overwritten in a rotating manner. These MIDI files can then be precisely triggered within MaxMSP (e.g., when a specific pitch is detected, a stored MIDI file is played back) and integrated into the live electronic performance.
Essentially, the system acts as a memory/archive that is generated from the live improvisation of the performer. Through a specific grammar created in OPUSMODUS, this musical material can then be re-injected into the live setting, forming a loop between improvisation, analysis, and compositional feedback.
Another development step would be to replace the current .txt-based communication with a direct OSC (Open Sound Control) connection, streamlining the entire process.
could sound like this: electric feedbacker guitar (live and improvised) + this system (in a test setup)

i'm close to the OSC solution... i can not read the DATA? but start/stop listening :-D any help possible?
-> how do i read *empfangene-osc-werte* ? or is there a bug in the code(defvar *empfangene-osc-werte* '()) ;; Liste zur Speicherung der empfangenen OSC-Daten (defvar *stop-osc-empfang* nil) (defun osc-receive-test (&key (port 7500)) (let* ((host #(127 0 0 1)) (s (usocket:socket-connect nil port :protocol :datagram :element-type '(unsigned-byte 8))) (buffer (make-array 1024 :element-type '(unsigned-byte 8)))) (format t "Lausche auf OSC-Port ~A...~%" port) (unwind-protect (loop ;; Hier prüfen wir das Abbruch-Flag until *stop-osc-empfang* do (multiple-value-bind (size from-host from-port) (usocket:socket-receive s buffer (length buffer)) (let* ((message (subseq buffer 0 size)) (decoded (handler-case (osc:decode-message message) (error (e) (format t "Fehler bei der Dekodierung: ~A~%" e) nil)))) (if decoded (progn ;; Wenn dekodiert, speichern wir die Nachricht in der Liste (push decoded *empfangene-osc-werte*) (format t "~&Empfangen: ~S~%" decoded)) (format t "Ungültige Nachricht empfangen: ~S~%" message))))) (when s (usocket:socket-close s))))) (osc-receive-test) ;; start (setf *stop-osc-empfang* t) ;; stop -
at the moment i'm trying other solutions to receive (more or less) live-data from MaxMSP (i can't figure it out in OSC) to do something with it - and do not block through "loops that read the new data" my automated-/live-coding
in MaxMSP: i write/store my data as txt-file (by WRITE) - every x seconds
i read it by a background-process in OPUSMODUS by the following code
;;; THE FUNCTION to read the txt-file (defun read-text () (loop do (setf x (with-open-file (stream "/Users/...../pitch_list.txt" :direction :input) (let ((content (make-string (file-length stream)))) (read-sequence content stream) content))) do (sleep 3))) ;; BACKGROUND PROCESS proceeding the function (mp:process-run-function "Mein-Prozess" nil #'read-text)so i'm generating mini-scores/snippets (with all the possibilities of OPUSMODUS) and send it back or store it as/in a midi-file-library to play them on a specific CUE (bang) in MaxMSP to coordinate and trigger them with other things i only can do in MaxMSP.
in this way you could also feed your LIVE-CODING-PERFORMANCE - under the hood - by external datasets. reading the new/other set all x-seconds.
the advantage (?) is that you do not have to read the values with a loop or constant new evaluation, which is always updated automatically in the background

this is the working example for send. very basic, i can send all in my FORMAT, i used i for several pieces... (but just SEND)

A convulsive example could be: I have a process running in Max MSP (pulse in constantly changing current values), these are influenced via an audio signal. If a certain value is reached (threshold value), MaxMSP should send the last 20 values to OM. OM then sorts these values in a new sequence, sends them back to Max and reads them again as a current values.
Instead of sorting, other complex functions of OM could also be applied to these values and then reinterpreted.
I think you could use the specific skills of the platforms and have them interacted.
just sending LISTS between the platforms and starting to EVAL in OM
MAX send could be a just MESSAGE, receiving too. one MAX-bang should send a "message", like shown in the MAX-patch
-
to receive data from Max MSP to...
1) start/eval functions by MAX in OM
2) to produce "new lists" (and sending it back to Max) based on data received from MAX (could be any data, internal processes , sensor data, whatever)...
so you could produce data for future processes in MAX (for realtime) based on incoming data...
years ago there were some LISP-inplementations in MAX (don't work anymore), but perhaps the communication via OSC would work too... and could be a simple solution. just having an "INTERFACE"

Yes, but I will control/trigger the MIDI files and their change in real time, via audio and filter thresholds (live-electronics). So this can only be done in Max MSP.
My greatest wish: OM would be "integrated" in Max MSP. In the past there were some LISP-implementations in Max MSP, unfortunately no longer. I would be happy to expect certain processes in lists within Max (within a real time processes) and LISP/OM is optimal for this - this is much more cumbersome directly in MaxMSP
Another way would be to let OM and Max MSP run in parallel and to be able to evaluate a function in OM at a Cue from Max and then be able to use the result again in Max. Can you already do about OSC but is that very complex? Or does someone practice that?
-
I am currently learning Max MSP for a project, but I would like to use a part of computing structures that I can generate much easier in Opusmodus. So I write code in OM (sorting algorithms for some clicks), test it (and modify my code), then export it to a library in Max MSP. I can now call up/coordinate the MIDI files in realtime etc ... in Max MSP.

LUTOSLAWSKI often used independent tempi between the instruments (string quartet etc...) and very simple "notation of rhythmic gestures". so it was possible to get a "begrenzte aleatorik" (and global complexity) and freedom in playing at the same time. you could do it like that:

Opusmodus / A musical reflection tool
At the beginning it should be noted that this is not a piece of music! I often try out new material in Opusmodus, test ideas, almost improvise with it. It is a good tool for me to check my idea, to reflect it, to change rules/ideas. A musical reflection tool.
Basic idea:
I would like to build a texture (based on a Pitchfield/Chord), which is structured by scales/arpeggia, should be played by a fender rhodes and two sine players. Each gesture should have a new pace (1/20 1/12 etc.) and a new dynamic, so that this texture has homogeneity on the side (through the chord), but is very precise articualted inside. The fender rhodes should and must be playable (= done by limiting the scales), sines can be "free" ...Result:
What I get with this few code is a sketch, now I can refine my rules and conditions (chord/tempi/rests) in OPUSMODUS. Likewise, I can now experiment (if this works now) in Ableton Live on the timbres, which surely will have i kind of a feedback on my CODING in OMN. A kind of circular working process... a
At the end:
I will write it down by hand (sibelius) to be able to articulate even more precisely (like i want it) than the code.
For the stage:
Coordiniaton will be done by click-track or https://polytempo.zhdk.ch
Have fun!
Greetings
