vector-to-length (with pitch-figurate) - audition tape

do you have some CODE to share?

Not much, but happy to share.


Somedays, I just set up a live audio host and some interesting instruments and samples, and then 'browse' the Opusmodus documentation. In these sessions, I am combining a playful way to add to my knowledge while generating audio materials via audition and MIDI Export for my library to be used as later combinatory/compound materials. As the title suggests, these are just live experimentations with 'vector-to-length',  along with variations on a theme to the value of 'vector-smooth' (from min to max value over session period).




(setf vector (gen-white-noise 10000))

(setf v2l-1 (vector-to-length '1/128 -3 13 vector))
(setf v2l-s-1 (vector-to-length '1/128 -3 13 (vector-smooth 0.1 vector)))

(setf chromatic-12 '(c2 cs2 d2 ds2 e2 f2 fs2 g2 gs2 a2 as2 b2))
(setf chromatic-16 '(c2 cs2 d2 ds2 e2 f2 fs2 g2 gs2 a2 as2 b2 c3 cs3 d3 ds3))


(setf voice-1 (make-omn
               :length (length-weight v2l-s-1 :weight '(34 1))
               :pitch (span v2l-s-1 chromatic-16)
               :velocity (messiaen-permutation '(ff f mf mp p))))



...and with pitch-figurate and additional permutation:


(setf voice-1 (make-omn
               :length (length-weight v2l-s-1 :weight '(67 1))
               :pitch (span v2l-s-1 (pitch-figurate 6 chromatic-12 :interval (messiaen-permutation '(1 -1 2 -2 3 -3 4 -4 5 -5))))
               :velocity (messiaen-permutation (messiaen-permutation '(ff f mf mp p)))))


 The pitch list is for the sequential triggering 'sample slices' via New Sonic Arts 'Vice',  each slice corresponding to a specific pitch (thus the pitch-figurate serves to add controllable variation of slice triggering). The exercise is focused on rhythm, but in the context of untraditional/non-percussion materials ;-) hth

Grand improvisation, cool indeed 😎

Wow, thank you...that means a lot coming from you :)


Even at my extremely novice level with Opusmodus, the possibilities of what I can accomplish towards my own goals (experimental electronics) are seemingly endless :)


The combination of the online documentation and the continuing insights/inspiration derived from this forum and it's generous and talented contributors....is making this first leg of my learning Opusmodus an extremely exciting and rewarding period of education...and as I am able generate and collect these audio materials into a personal library, no doubt Opusmodus will allow me to develop unique approaches to electronic musiking which is my primary driving force ;-)

      I just realized that would be great to have snippet audition and notation (Command+1) with the notation opening in separate window, like we have Evaluate and Audition and Notation - Window and in PS.
      Maybe not very difficult to implement, but great to have, to show to sutudents the gradual process of the compositional process, etc.

      I was able to set up Logic or Opusmodus playback via IAC driver by loading a Logic setup file into my workspace (saved in Documents folder). In this way, I can audition short snippets and lines of code, which playback through Logic just fine (OMN Audition + Notation). However, I'm having difficulties with evaluating and auditioning the whole score (Evaluate Score Audition + Notation).
      I'm including a short code example for your reference in case you have any feedback. And here's the listener error code:
      > Error: OMN Parse Error: fail
      > While executing: omn-to-ast, in process Listener-8(63).
      Thank you for your time and help!

      Greetings all:
      When I invoke this command (Evaluate and Audition and Notation) I get the compilation of the code and the notation but audition playback does not occur.  
      I get the following in the Listener:
      ambitus make-instrument viola ambitus make-instrument violoncello def-score, name: timeline 6 > audition-musicxml-last-score #<process play loop(17) [Reset] #x3020024491ED> 6 > compile-score #<score timeline>  
      However, when I invoke the command to audition the last score (from the menu or the keyboard shortcuts)  it plays.  I should note that I am playing out via MIDI to Logic.
      Am I doing something wrong?
      Many thanks,
