Lets say I have 2 measures of music.

I want to make random variations of the rhythms (not the pitches)

The result should fit in the initial 2 measures.

What is the function called for this.

I cannot remember ...

Thanks for help,

Is there one working with OMN?

yes

Several possibilities depend what kind of variations you want.

The simplest one is random order applied only to lengths.

 

(setf mat '((e d4 e4 fs4 gs4 q a4)(s b4 c5 b4 gs4 q a4 e fs4 e4)))
(rnd-order mat :type :length)

Another way I appreciate particularly is length divide:

(length-divide '((3 4)(1 2)) mat :set 'max)

but this last one add some intervals so it may be not what you're searching for...

S.

Thanks a lot. I found another one as well:

quantum

 

length-invert

 

produces great results as well:
 

(length-invert '(1/8 1/8 -1/8 1/4 1/4 -1/8))
=> (-1/8 -1/8 1/8 -1/4 -1/4 1/8)

(length-invert '(1/8 1/8 -1/8 1/4 1/4 -1/8) :swap t)
=> (1/8 1/8 1/4 -1/8 -1/8 1/4)

 

and works with omn sequence.
