[CM] newbie: rhythm confusion

[Orm Finnendahl]

Hi all,

sorry, I forgot to cc the list...

Hi Carl,

It's not necessary to create a new midi event each repetition of the
loop. It is sufficient to define one instance outside of the loop and
then use sv to fill the slots.

Here's an example (also defining all the patterns outside the loop):

(defprocess my-first ()
  (let (
        (curr-midi-note (new midi))
        (r (new rotation of '(q e. h s)))
        (k (new random of '((60 weight .2143)
                            (62 weight .0714)
                            (64 weight .1429)
                            (65 weight .0714)
                            (67 weight .2143)
                            (69 weight .1429)
                            (70 weight .1429))))
        )
  (process repeat 96
           do
           (sv curr-midi-note
               time (now)
               keynum (next k)
               amplitude .5
               duration (setf ba (rhythm (next r)))
               )
           (output curr-midi-note) 
           (wait ba))))

(events (my-first) "test.midi")
