yes, of course - from "BOTs" to a lot of small simple FUNCTIONS... but: not very well/smart coded (🙄) - i'm musician but only an "amateur programmer" with few experience -  and it's really NOT well documentated for other users. and another point, i have no idea how do that professionally with GUTHUB and these installation-things 😕
 
as ORDINARY text - no problem. perhaps i will share it like that on my website...
 
 

i'm very interested in!! thx to you JULIO!!! 🙂
strukturnetz is not a piece, it's "a kind of technique" he used 🙂
 
you could read about it here:
https://www.amazon.de/Differenzen-Poststrukturalistische-Beispiel-Lachenmann-Ferneyhough/dp/3931264157
 
listen here...
the STRUKTURNETZ is also "notated" in the score (on top)
 

like that? should work...
it "loops" x-times (depends on length of seeds-list) and collect the rhythms...
 
(setf seeds (vector-round 1 100 (gen-white-noise 8 :seed 13))) (setf rhythm (loop for i in seeds collect (euclidean-rhythm 16 4 16 's :type 2 :seed i)))  
 
perhaps there is an OPMO-solution, this is LISP

Thanks, Andre ! I will check the Lachenmann piece, for sure.
 
I was thinking in a possible algorithm for such function:
 
1) Take an OMN expression
2) Calculate the empty spaces (rest space)
3) Fill the spaces with notes, based on each gap, using a predefined quantization (1/16, 1/8, random, etc) and a filling density level (0-100 %,  of the space)
4) Fill the spaces with predefined pitch lists, motifs, rhythmmic sets, etc,  that can be trimmed, rotated and start on any note
5) Fill the spaces like mentioned before with some pitch quality control (tonality-map) and pitch melodic direction control (up, down, repeat, vector).
6) Fill the spaces like before with any predefined method
 
populate-spaces
populate-gap
fill-spaces
fill-gap
 
This would be really useful, IMHO.
 
All the best !

would be interesting. it has quite some (distant?) aspects of LACHENMANN's "strukturnetz", and could be nice to work in such an direction...

I will have a think.

or...
 
(loop for x from 7 downto 1 for y from 1 to 7 collect (list x 3 y))  

or...
 
(loop for x from 7 downto 1 for y from 1 to 7 collect (list x 3 y))  

i have been working with conTimbre for a long time and it is exactly what i was looking for. playing techniques can easily be done by OPMO or SIBELIUS (vst3) via program changes. it has a great many different playing techniques. I always found IRCAM_LIB to be very inadequate, as there were not enough playing techniques etc. / you can also control CT via OSC (and as standalone or via MAXMSP). when I wrote for ensemble with additional e-player, CT-live always worked very well.
 
(The only negative point I could say is that there are a few SAMPLES that weren't played / recorded very well. But with the size of the library, that's okay with me)

I am implementing a library of algorithms for music generation using Opusmodus. Here are 3 snippets generated using this library. The midi outputs are sent to Reaper DAW, which in turn uses instruments available in Propellerhead Reason 11 (through VST3i Reason Rack Plugin).

Dear all
 
Today I dealt briefly how to control PROCESSING (software and programming language) by Midi. There is a great interface for this: "rwmidi" by Giuseppe Torre. You can download and install it, it works fine!  
 
A short Video (no Sound) with a very simple Processing Example
 

movie.mov  
I think this is a good combination if you want to visualize your midi output (or just use de midi-data in realtime)  or if you want to program a separate VISUAL track in OPMO. Here is a small example (I can't program usable in PROCESSING yet, sorry :-)) Downloads etc. are here ...

here's an example (from my current work)...
 
this little video shows how i generate/display SCORE (instrumental parts) on a screen + virtual conductor (piano part). the example is "nonsense", but shows how it looks/works... you see the bars (generating), the cue, beat... and the arrow (that shows you where to read/play) ...also you hear some bad (sry) sound-simulation of the setup.
 
in this way i can generate a whole piece in realtime on STAGE (all musicians will read their part from their own screen). this one will be for 5 instruments, ePlayer and modular synthesizer. during the performance an algorithm (or some data-streams) will generate the piece in OPMO. with OSC i can send all datas (score, beat, tempo..)  from OPMO to POLYTEMPO-NETWORK  (https://polytempo.zhdk.ch) and work and coordinate different independent tempo layers, conducting etc...
 
for more POLYTEMPO informations... have a look here: https://polytempo.zhdk.ch

MIDI ENTRY
 
To start the MIDI input into your score file, select the command MIDI Entry from the Tools menu. When MIDI Entry is ON, the Listener echo bar will change to orange:
 

 
Now you know the MIDI Entry is ON. Depending on the position of the pitch-bend wheel and the modulation wheel as well as the position of the sustain pedal the colour of the Listener echo bar will change.
 
To make the MIDI Entry as functional as possible there are a number of commands that will increase the speed of your work without the need to move away form your MIDI keyboard.
 
Every entry is octave independent, except the pitch entry.
 

 
 Pitch                                  
Enter pitch symbols and chords into your score.
 
 Length and Tuplet

Pitch-Bend: Down-Half
C stacc Cs ord D marc Eb fermata E mart F ten Fs pizz G leg Gs trem A tie Bb ped1 B ped  
 Microtonality and Commands             
Modulation Wheel: Up
Add a microtonal symbol next to the pitch symbol.
 
F   + G   - A   . B   .. C   parenthesis pair D   open parenthesis E   close parenthesis Cs move forward char Eb move backward char Fs delete backward char Gs undo Bb new line and indent Note: If you enable MIDI input with the modulation wheel up, you need to move it down and up again in order for it to be considered up.
 
Entries with Sustain Pedal Down
 
 Pitch                                  
Add a pitch symbol next to the previous pitch (chord).
 
 Length and Tuplet                      
Pitch-Bend: Up-Full
Add a length entry to the previous length value (combine length).
 
 Length-rest and Tuplet                 
Pitch-Bend: Down-Full
Add a length-rest entry to the previous rest value (combine length).
 
 Velocity                               
Pitch-Bend: Up-Half
Add < or > dynamic symbol to the previous velocity value.
 
 Attribute                              
Pitch-Bend: Down-Half
Add (+) attribute to the previous attribute value (combine attributes).
 
Examples:
c4e4g4 Enter a chord c4e4g4 on your MIDI keyboard or pitch by pitch: c4 e4 g4 with sustain pedal down. (q c4 mp e4 g4) 1. Modulation wheel up then C => () 2. PB-UpF then E => (q) 3.

MICROPOLYPHONY is a polyphonic musical texture developed by György Ligeti which consists of many lines of dense canons moving at different tempos or rhythms, thus resulting in tone clusters vertically. According to David Cope, "micropolyphony resembles cluster chords, but differs in its use of moving rather than static lines"; it is "a simultaneity of different lines, rhythms, and timbres".

Hi,
 
here's a function i've made for my own usage and i think could be useful for others.
It is a split point function which divide an OMN flux according to a list of split points.
 
Attached, you will find the French doc of the function 😉
