Help on Get-Beats

[JulioHerrlein]

Dear Friends , 

 

I have this question regarding Get-Beats Function.

 

All the best !

Julio

 

;;; THIS WORKS !

(setf omn-forum '((h b4 s d5 mf ord g5 ord c5 ord e. a5 ord s b5 ord e5 ord fs5 ord d5 ord e g5 f stacc c5 stacc a5 stacc - b5 stacc q e5 mf ord)(h bb4 s d5 mf ord gb5 ord c5 ord e. ab5 ord s b5 ord e5 ord fs5 ord d5 ord e g5 f stacc c5 stacc a5 stacc - b5 stacc q eb5 mf ord))

(get-beats '(
(1 1 (1 2 4 7 5 8 6 3)) 
(1 2 (1 2 4 4 4 7 6 3))) 
omn-forum)

;;; But THIS WON´T WORK - Why ?

(setf bts (rnd-unique 8 '(4 7 5 8 3 6 1 2)))

(get-beats '(
(list 1 1 bts) 
(1 2 (1 2 4 4 4 7 6 3))) 
omn-forum)

(get-beats
 (list (list 1 1 bts) '(1 2 (1 2 4 4 4 7 6 3)))
 omn-forum)

Thanks a lot !

Happy 2023 !

Dear friends,

 

Is there a way to use the rnd-beat-order function but specifying a list of beats ? The get-beats is the way in this case ? Or there is such a function like beat-order ? or maybe a space for determining the order inside the rnd-beat-order function ? In negative case, I´ll use the get-beats for doing this.

 

All the best !

Dear friends, 

A LISP question...

 

;;; Dear Friends,

; LISP question for using with get-beats

;;; voice and bar list
((1 1) (1 2) (1 3) (1 4) (1 5)) 
;;; beats 
((1 2) (1 2 3 4 5 6 7 8) (1 2) (1 2 3 4 5 6 7 8) (1 2))

;;; matrix result
(matrix-transpose '(((1 1) (1 2) (1 3) (1 4) (1 5)) ((1 2) (1 2 3 4 5 6 7 8) (1 2) (1 2 3 4 5 6 7 8) (1 2))))

;;; desired result to use in gen-beats

((1 1 (1 2)) (1 2 (1 2 3 4 5 6 7 8)) (1 3 (1 2)) (1 4 (1 2 3 4 5 6 7 8)) (1 5 (1 2)))

;;; how can I achieve the last result in LISP ? That kind of list, like (x x ( y z)) kind of list ?

;;; Best !

 

Summarizing...

 

How to transform this

 

(((1 1) (1)) ((1 2) (1 3 5 7)) ((1 3) (1)) ((1 4) (1 3 5 7)))

 

into this

 

((1 1 (1)) ((1 2 (1 3 5 7)) ((1 3 (1)) ((1 4 (1 3 5 7))

 

How is the name of this type of list ?

 

Best !

This is a suggestion for a function like

 

get-bars-beats

 

to be used in conjunction with get-beats 

 

;;;This is an idea to get all the bars and beats from an OMN expression to be used/edited with GEN-BEATS

(progn
(setf omn-idea (gen-repeat 5 '((q b4 p<f tie+long) (q b4 s d5 mf ord g5 ord c5 ord e. a5 ord s b5 ord e5 ord fs5 ord d5 ord e g5 stacc c5 stacc a5 stacc - b5 stacc q e5 ord) (q gb4 p<f tie+long) (q gb4 s fs5 mf ord cs5 ord gs5 ord e. f5 ord s eb5 ord bb5 ord c5 ord fs5 ord e cs5 stacc gs5 stacc f5 stacc - eb5 stacc q bb5 ord) (q as4 p<f tie+long))))

(setf all-bars 
(cdr (gen-divide 2 (flatten 
(matrix-transpose (list
(gen-divide 1 (gen-repeat (get-count (get-count omn-idea)) '(1)))
(gen-divide 1 (gen-integer (get-count (get-count omn-idea))))))))))

(setf beats-zerobase 
(loop for i in 
(find-everyother 3 (flatten (get-time-signature (gen-divide 1 (get-span omn-idea)))))
 collect (gen-integer i)))

(setf all-beats (gen-divide (get-count beats-zerobase) (loop for i in (flatten beats-zerobase)
collect (+ 1 i))))

(setf all-bars-n-beats (matrix-transpose (list all-bars all-beats)))
)

 

The result is this

 

(((1 1) (1 2)) ((1 2) (1 2 3 4 5 6 7 8)) ((1 3) (1 2)) ((1 4) (1 2 3 4 5 6 7 8)) ((1 5) (1 2)) ((1 6) (1 2 3 4 5 6 7 8)) ((1 7) (1 2)) ((1 (1 2 3 4 5 6 7 8)) ((1 9) (1 2)) ((1 10) (1 2 3 4 5 6 7 8)) ((1 11) (1 2)) ((1 12) (1 2 3 4 5 6 7 8)) ((1 13) (1 2)) ((1 14) (1 2 3 4 5 6 7 8)) ((1 15) (1 2)) ((1 16) (1 2 3 4 5 6 7 8)) ((1 17) (1 2)) ((1 18) (1 2 3 4 5 6 7 8)) ((1 19) (1 2)) ((1 20) (1 2 3 4 5 6 7 8)) ((1 21) (1 2)))
 

Not yet appropriate to use in GET-BEATS, but close...

 

All this could be made inside one function, to extract, bars and beats in the form of GET-BEATS function.

 

Best,

Julio

(loop for i in b-val
      for j = (first i)
      collect (list (first j) (second j) (second i)))

Thanks a lot, Janusz ! 

(get-bars-beats) would be useful and easier !

Best !
