[change randomly lengths to rests]

Sometimes its correct, sometimes not ...

Did you tried it with my seed? What was your result?

[change randomly lengths to rests]

Something like this:

 

(defparameter durations '(15/16 15/32 1/32 1/32 1/32 61/32 1/32 1/2 1/32 5/32 1/32 13/16 17/32 3/2 9/16 7/16))

(defun length-to-rnd-rest (numb dur-lst)
  (let* ((llst (- (length dur-lst) 1))
         (minnumb (min numb llst))
         (posns (sort-asc (rnd-unique minnumb (gen-integer 0 llst)))))
    (loop for i in dur-lst
          for j from 0
          collect (if (member j posns)
                      (* -1 i) i ))))

(length-to-rnd-rest 5 durations)

 

I get only 4 rests in this example:

(defparameter durations '(15/16 15/32 1/32 1/32 1/32 61/32 1/32 1/2 1/32 5/32 1/32 13/16 17/32 3/2 9/16 7/16))

(length-invert durations :section (rnd-sample 5 (gen-integer 0 (1- (length durations))) :norep t :seed 4))

;; => (15/16 15/32 1/32 1/32 1/32 61/32 1/32 1/2 -5/32 -13/16 1/32 -9/16 17/32 3/2 -1/32 7/16)

 

[change randomly lengths to rests]

Is there a function with which I can change randomly a defined number of lengths in a list to rests?

Thanks, Achim

 

[Documentation PDF copy paste problem]

17 hours ago, opmo said:

This is not an error. The documents (pdf) are not really for text copy/past. You never know how pdf behaves. 

And if you copy you need to take some care of the code.

I think, they should be usable for copy & paste. Its probably a common use to copy extracts from the documentation for further coding, don't you think?

[fill-space function]

Hi,

attached is a function I wrote for a piece.

Does anybody have an idea how to extend this with a seed functionality. I have tried a few things but so far without any real success ...

The other thing: It can take quite a while until a possible solution ist found. Does anybody have an idea to improve the calculation speed?

Thanks and best,

[Find all combinations that add upto given number]

I use this to select different unique modules for Live-Electronics.

Here ist my adapted function:

 

(defun comb-to-sum (n &key (reps t))
  (let* ((nums (gen-integer 1 n))
         (x 0)
         (result
          (find-unique
           (sort-asc
            (flatten-sublist
             (loop repeat n
               for i = (combination2 (incf x) nums)
               collect (loop for c in i
                         if (= (sum c) n)
                         collect c)))))))
    (if reps
      result
      (loop for i in result
        when (equal (sum (remove-duplicates i)) n)
        collect i))))

(comb-to-sum 5 :reps nil) ; => ((5) (1 4) (2 3))

 

[Find all combinations that add upto given number]

I would actually need ALL possibilities …

[Find all combinations that add upto given number]

Is something like this implemented in OM or has anybody written a function for it?

 

Input: N = 3
Output:
1 1 1
1 2
3
Input: N = 5
Output:
1 1 1 1 1
1 1 1 2
1 1 3
1 2 2
1 4
2 3
5

[ps display bug?]

This is correct. any process of pitches will end with:

c, cs d eb, e, f, fs, g gs, a, bb b

 

In my understanding it should be exactly as notated, not interpreted.

[Clefs not exported with music-xml]

Hi,

it seems that the automatically created clefs e.g. from ps are not exported with music-xml. When I open these files in Sibelius the clefs are gone.

Any suggestions how to solve or work around this?

Hi,

is there a print function for the midi display?

At the moment I am using "zoom to fit" in fullscreen mode and then make a screenshot but this is a little cumbersome ...
