I think you can use gen-chord3.
 
also i have finished the function you asked in another post about a different version of add-interval-if-length.
 
This one is make-chord-if-length and is based on gen-chord3.
 
i'll post it here for convenience but will also post it in programming forums section.

Here's a new function a bit similar to my old "add-interval-if-length" function but bit more sophisticated.
It use gen-chord3 to create chord on defined length.

OVERWRITE FUNCTION: first time i'm working with this function (i coded it a year ago)... to overwrite the output/score => INSERTS....
- and it's very useful, perhaps JANUSZ could code an official OPMO-version of this which works perfect?

This is for generating some jazz licks in the style of the LINEAR EXPRESSIONS, by jazz guitarist PAT MARTINO.
The rhythm slots of the example contain the same 16th value, but it can be worked out as Rhythmic Cells. I was testing straight 16th lines.

I own the 2 library and for me ConTimbre is indeed much better (much complete)  than IRCAM instruments lib.

So I didn't really know what an IDE was..it's an Integrated Development Environment..is that right?
Well anyhow I just wanted to share my enthusiasm for Opusmodus' idea of an integrated workspace...being able to have pdf books available full screen with a shortcut is amazing...and pictures and audio etc. I am a big fan of Wooden Books for instance and bam..there they are in my composing space for reference. 
I'm kind of thinking this is how all "composing" software should be..but mostly now it seems to me to be about a graphical interface that is irrelevant alongside a multitrack recorder paradigm.
 
Anyhow happy to be on this journey (())
 

Hello, All
 
The idea is to generate some improvised lines over the Giant Steps progression.
Every time the code is evaluated, a different comping and improvisation is generated.
In this first effort, the improvisation is generated by the arpeggios resultating from the voice-leading of the progression.
After that, I want to code some superimpositions of other chord substitutions.
 
This is something I came with after studying the Harmonic-Path Function ( through some example by Stephane Boussuge)
I also got some Drums from Jazz Trio, by Janusz Podrazik.
Below is the commented code and an mp3 showing the result.
 
All the best,
 
Julio

I agree that this is useful, and therefore I also implemented a similar functionality in my function rotate-omn 🙂  You can find its documentation at https://tanders.github.io/tot/sources/form.html#_g229430 and download the whole library at https://github.com/tanders/tot.
 
BTW: You meanwhile should also have quite a sizeable collection of custom functions for Opusmodus. While not sharing them together in some kind of library as well? 
 
Best,
Torsten
 

Hi Julio,
it could be possible but a bit outside my programming capabilities, but Janusz is certainly capable to achieve this.
And , as  you, i would love this feature 🙂
S.
 

Dear Janusz,
 
It would be great to have this function in the core functions of version 1.3
 
Best,
Julio
 
Dear Stephane,
 
Can we use this function to add more than one interval to each note ?
This can add one  interval, but I'm refering to add also two intervals, forming a trichord.
1) So the interval list would look like this, for adding intervals:
 
(add-interval-if-length '((q c4 d4 e4 f4 e g4 a4) (e f4 e4 q d4 c4 a4 g4 f4)) :interval-list '(5 4)) 2) And like this, to alternate beetween a major triad and a perfect fourth:
(add-interval-if-length '((q c4 d4 e4 f4 e g4 a4) (e f4 e4 q d4 c4 a4 g4 f4)) :interval-list '((4 3) 5)) Is it possible ?
Any suggestion ?
 
Best,
Julio

A new CIRCLE-PITCH-PLOT function (examples below) will be part of the forthcoming Opusmodus 1.3.
 
The function CIRCLE-PIOTCH-PLOT returns a geometrical representation of relationships among the 12 pitch classes of the chromatic scale in pitch class space and provides an easy way to identify patterns and similarities between harmonic structures.
 
Clockwise motion represents ascending pitch motion, and counterclockwise motion represents descending pitch motion.
 
Examples:
 
Major Triad
(circle-pitch-plot '(c4e4g4))
 
Minor Triad
(circle-pitch-plot '(c4f4ab4))
 
Augmented Triad
(circle-pitch-plot '(c4e4gs4))
 
All 4 augmented triads
(circle-pitch-plot '(c4e4gs4 db4f4a4 d4fs4bb4 eb4g4b4))
 
 
With :style :fill
(circle-pitch-plot '(c4e4gs4 db4f4a4 d4fs4bb4 eb4g4b4) :style :fill)
 
Example with chord names.
Fully-Diminished 7th Chord
(circle-pitch-plot 'dim7)
 
All 3 fully-diminished 7th chords
(circle-pitch-plot '((c4 dim7) (cs4 dim7) (d4 dim7)))
 
Whole-Tone Scale
(circle-pitch-plot '(0 2 4 6 8 10))
 
The complex of 2 Whole-Tone Scale
(circle-pitch-plot '((0 2 4 6 8 10) (1 3 5 7 9 11)) :style :fill)
 
Chromatic Scale
(circle-pitch-plot 'chromatic :point-radius 4)
 
The complex of 6 tritones
(circle-pitch-plot '((0 6) (1 7) (2 8) (3 9) (4 10) (5 11)) :point-radius 4)
 
Tonalities
(circle-pitch-plot 'mixolydian-greek :point-radius 4)
(circle-pitch-plot 'bartok :point-radius 4)
(circle-pitch-plot 'messiaen-mode3 :point-radius 4)
(circle-pitch-plot 'hyojo :point-radius 4)
 
Contrary Motion
(circle-pitch-plot '(0 1 11 2 10 3 9 4 8 5 7 6)              :sort nil :join-first nil)
(circle-pitch-plot '((0 1) (0 2) (0 3) (0 4) (0 5) (0 6)                (0 7) (0 8) (0 9) (0 10) (0 11)) :point-radius 4)
 
Example with Forte notation
(circle-pitch-plot '(6-32 6-7))
 
Example with omn-form sequence and :type :pitches
 
(circle-pitch-plot '(((leg s g2 p dbow+sul d3 sul b3 dig1 a3 b3 d3 b3 d3)                 (leg g2 d3 b3 a3 b3 d3 b3 d3)))              :type :pitches)  

 
Circle types
(circle-pitch-plot '((4 9 11) (3 5 10) (0 3 6 9)) :style :fill)
(circle-pitch-plot '((4 9 11) (3 5 10) (0 3 6 9))              :type :pitches :style :fill)  

(circle-pitch-plot '((4 9 11) (3 5 10) (0 3 6 9))              :type :fifths :style :fill)  

 
Examples with :sort and :remove-duplicates set to nil
(circle-pitch-plot '(0 2 6 0 3 7 0 4 8))
(circle-pitch-plot '(0 2 6 0 3 7 0 4 8) :sort nil)
(circle-pitch-plot '(0 2 6 0 3 7 0 4 8)              :sort nil :remove-duplicates nil)
(circle-pitch-plot '(0 2 6 0 3 7 0 4 8)              :sort nil :remove-duplicates nil :join-first nil)  

(circle-pitch-plot '(8 4 2 0 10 2 8 10 4 6 8)              :sort nil :remove-duplicates nil)
 
Best wishes,
Janusz

You can also use the Opusmodus function length-map for doing that.

I don't know because i am on the beta of the future Opusmodus version and on this one, i can change the background color in real time, ie. move the color cursor and color changes immediately.
May be try to use the Toggle dark option in preference to see if it works.
 
SB.

in my personal view:
 
- for algorithmic composition ...you have first to be a composer/musician - because it's a lot more about music then about code (i learned a little bit to code, because i was interested in this "kind of thinking" about art and music
 
- so, i think, if you want to work with algorithms you have to handle some code (like in music you have to handle some pitches/sound/rhythms)
 
- when you have a look to the history of algorithmic composition you see some software like: common music, open music, pwgl, patchwork, also supercollider or MAX etc, it has always to do with computer/code/algorithm. also PWGL, commonmusic, openmusic... are working with LISP (or parts of it), so i think, that's the thing. mostly i like in OPUSMODUS the direct connection to the SCORE etc... i like it also because it's very OPEN for some own things/code/ideas (because it's close to the basic COMMON LISP)...
 
- you could work with all the EXAMPLES in the library, take it, do some smooth changes and have a look what happens...

It is the start of one of my composition but i give it here as a pedagogical example.

It is the start of one of my composition but i give it here as a pedagogical example.
Happy reading.
