Sounds Great, Stephane! Somewhat jazzy and groovy in my perception. 

Any hint of the code/method used? 

Best! 

 

Hi Julio,

It is mainly based on continuous variation on 2 Slonimsky patterns.

S.

The chords are also derived from the slonimsky patterns?  Do you remember  wich slonimsky pattern you used?  Im teaching slonimsky patterns to my students and using opusmodus in the class. This is Great! Best Julio 

No, chords are rotational intervals addition, dependant to the type of lentgh.

I've used for that my function: add-interval-if-length revised by Torsten.

Here it is:

 

;;; ==============================================
;;; UTILITY FUNCTIONS
;;;
(defun add-interval-if-length-aux (omn &key (test #'>) (length-val 1/8) (interval-list '(4 3 4 7 4 3 5 4 7 3)))
  (let ((s-events (single-events omn)))
    (loop 
      for e in s-events
      for i in (gen-trim (length s-events) interval-list)
      when (funcall test (omn-encode (first e)) length-val)
      append (omn-replace :pitch (chord-interval-add (list i) (list (second e))) e)
      else append e)))

;(add-interval-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '(10 11))

;;; =============================
;;; MAIN FUNCTION
(defun add-interval-if-length (omn &key (test #'>) (length-val 1/8) (interval-list '(4 3 4 7 4 3 5 4 7 3)))
  (do-verbose ("add-interval-if-length")
    (let ((test-fn (case test
                     (> #'>)
                     (< #'<)
                     (= #'=)
                     (otherwise test))))
      (if (listp (car omn))
        (mapcar #'(lambda (x) 
                    (add-interval-if-length-aux x :test test-fn :length-val (omn-encode length-val) :interval-list interval-list)) 
                omn)
        (add-interval-if-length-aux omn :test test-fn :length-val (omn-encode length-val) :interval-list interval-list)))))
  

;(add-interval-if-length '((q c4 d4 e4 f4 e g4 a4) (e f4 e4 q d4 c4 a4 g4 f4)) :interval-list '(10 11))
;(add-interval-if-length '((q c4 d4 e4 f4 e g4 a4) (e f4 e4 q d4 c4 a4 g4 h f4)) :interval-list '(3 4) :test #'>= :length-val 'q)

All the best

Thanks, Stephane !

Best,

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

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.

 

Now, finally it's done by myself.

SB

Yes, we can add the function to our system. I will try to make it happen for 1.3

a release date für 1.3 ?

greetings
