VOICE LEADING FUNCTIONS

 

CLOSEST-PATH

 

The function CLOSEST-PATH returns a series of chords taking the closest path to the previous chord.

 

(closest-path '(b4g4e4c4 c5a4e4f4 b4a4f4d4 b4g4e4d4))

COMPARATIVE-CLOSEST-PATH

 

The function COMPARATIVE-CLOSEST-PATH returns a series of chords taking the comparatively closest path to the previous chord, derived from randomising the pitch order of a given chord before the ‘find closest interval’ process.

 

(comparative-closest-path '(b4g4e4c4 c5a4e4f4 b4a4f4d4 b4g4e4d4))

RELATIVE-CLOSEST-PATH

 

The function RELATIVE-CLOSEST-PATH generates cartesian series of intervals form a given chord. It then selects randomly the relative closest path (transition) to the previous chord.

QUICK START WORKSPACE


To update your 'Quick Start' workspace to the latest version you need to delete the 'Quick Start' folder from the Opusmodus directory first.

After the deletion go to the Opusmodus menu 'Help' and select 'Install Quick Start Workspace'.

To open the new 'Quick Start' workspace file simply select 'Open Quick Start Workspace' form the 'Help' menu.

 

That's all for now,

best wishes,

Janusz

      Free update for Opusmodus 1.3. users.
      It includes a support for a second screen and multi voice snippets.
      The new UNFOLD system opens up a whole new set of possibilities for the composer using OPUSMODUS.
      Additional library directory: 'Def-Instrument-Sets'. 
       
      New functions:
      DEF-INSTRUMENT-SETS
      Use this function to define the instrument-sets with a given name. With named instrument-sets a composer can customise OPUSMODUS to reflect MIDI synthesisers or samplers which a studio system (inboard or outboard) might contain. The DEF-INSTRUMENT-SETS function is an essential companion to the PS function (PS stands for ‘Preview Score’ or, ‘Preview Snippet’). To create instrument-sets is fairly easy to do as it resembles the instrument setup from the DEF-SCORE instance.
       
      The instrument-set template:
      <instrument-name> (:layout <layout>   :port <port>   :channel <channel>   :sound <sound-set>   :program <program>   :controllers <controllers>   :pan <panning>   :volume <volume>)  
      To explain how it all works we will define new instrument-sets with two instruments. In our example we will use :oboe and :bassoon as our instrument names with a library name: my-inst. The next step we need to do is to select the corresponding instrument layout. The predefined layouts you will find in the ‘Instrument Layout Presets’ document in the System/Layout library:
       

       
      Examples:
      (def-instrument-sets my-inst                      :instruments   (:group group           :oboe           (:layout oboe-layout                    :port nil                    :channel 1                    :sound 'gm                    :program '(oboe)                    :controllers nil                    :pan (pan 0)                    :volume 92)           :bassoon           (:layout bassoon-layout                    :port nil                    :channel 2                    :sound 'gm                    :program '(bassoon)                    :controllers nil                    :pan (pan -10)                    :volume 92)           ))  
      Here is how an instrument from a defined instrument-sets name might be entered into PS:
      (ps 'my-inst     :oboe (list '((s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                   (s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                   (s a4 leg d5 leg cs5 leg b4 leg a4 leg g4 leg)                   (s fs4 leg d4 leg e4 leg cs4 leg e d4)))     :bassoon (list '((e fs3 d3 e3)                      (e fs3 d3 e3)                      (e fs3 g3 a3)                      (e d3 a2 d2)))     :key-signature '(d maj)     :time-signature '(3 8 1)     :tempo 112)  
      You can define as many instrument-sets instances as needed.
       
       
      PS
      Use this function if you are looking for a quick preview of your score or when a snippet (especially for education) needs a full representation of the intended notation. The PS function name stands for ‘Preview Score’ or ‘Preview Snippet’. In the following examples we use the default instrument-sets library, defined in the ‘GM Instrument Sets.lisp’ file, which you will find in the Library panel. How to create your own instrument-sets library, you will find in the DEF-INSTRUMENT-SETS document.
       
      Instrument treble:
      (ps 'gm :treble (list '((s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                 (s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                 (s a4 leg d5 leg cs5 leg b4 leg a4 leg g4 leg)                 (s fs4 leg d4 leg e4 leg cs4 leg e d4)))     :key-signature '(d maj)     :time-signature '(3 8 1)     :tempo 112)
       
      Instrument piano:
      (ps 'gm :p (list '((s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                (s a4 leg d5 leg fs4 leg d5 leg g4 leg d5)                (s a4 leg d5 leg cs5 leg b4 leg a4 leg g4 leg)                (s fs4 leg d4 leg e4 leg cs4 leg e d4))              '((e fs3 d3 e3)                (e fs3 d3 e3)                (e fs3 g3 a3)                (e d3 a2 d2)))     :key-signature '(d maj)     :time-signature '(3 8 1)     :tempo 112     :title "G. Ph. Telemann, 12 Fantasie per clavicembalo TWV 33-n.1, 1732")  

       
      Examples:
      The examples below demonstrate how quickly you can preview your progress at any stage of your work ie. voices, instrumentation etc…
       
      (setf p1 '(q d4 pp s eb4 < leg g4 < leg bb4 < leg a4 q. cs5 mf -e       3q gs5 > leg fs5 > leg c5 > b4 > leg f4 leg e4) p2 '(t d4 < leg eb4 < leg g4 < leg bb4 q. a4 marc       t fs4 mf leg gs4 leg e. c5 e b4 t f5 leg e5 leg d5 leg       eb5 3q bb5 > a4 > bb5 > e a4 pp stacc -e) p3 '(q d5 leg eb5 3q g4 stacc bb4 stacc a4 stacc       e. cs4 marc s gs4 leg q gs4 -q) p4 '(-q. e d4 pp q. eb5 mf e g4 q bb4 trem a4 trem) p5 '(q. fs3 pp 3e c3 < leg b4 < leg f4 e d3 mf s eb3 leg       g3 leg bb3 leg a3 e fs3 leg fs3 3e gs4 > stacc       c5 > stacc b5 > stacc t f5 pp e.. e5) p6 '(q cs3 pp -q t gs3 marc e.. fs3 mf leg e c3 -e       t b3 leg f3 q.. e4 pp) )  
      Please note how the list function is used to enclose the instrument voices. The number of voices in an instrument should not exceed the layout of a particular instrument. For example a piano uses a two staff notation therefore the input should be a two lists in a list (list (list right-hand) (list left-hand)).
       
      (ps 'gm :p (list (list p1) (list p6)))  

       
       
      Instrument oboe, clarinet and bassoon:
      (ps 'gm :ob (list p1)     :cl (list p3)     :bn (list p6))  

       
      Brass Quintet:
      (ps 'gm :b5 (list p1 p2 p3 p4 p5))  
       

       
       
       
      DEF-UNFOLD
      UNFOLD
       
      The DEF-UNFOLD and UNFOLD function opens up a whole new set of possibilities for the composer using OPUSMODUS. It can prove a very powerful tool in defining methods (functions) from the outset, for a specific work or as a global index of your most used functions. To be able to store methods, processes and solutions and call them at anytime becomes a valuable resource for a composers workflow. This function is a companion to the UNFOLD function.
      (def-unfold m1   var (:pitch (pitch-variant x :variant '?))   dyn (:velocity (velocity-to-dynamic x))   )  
      (setf omn '(s bb4 p a4 h. db4 t gs4 mf fs4 c5 b4 q f5 e5))  
      To run the defined methods in a given omn-form sequence use the UNFOLD function:
      (unfold 'm1 '(var dyn) omn)  
      Examples:
      (def-unfold m2   7   (:pitch (pitch-transpose 7 x))   -12 (:pitch (pitch-transpose -12 x))   ret (:all (gen-retrograde x :flatten t))   var (:pitch (pitch-variant x :variant '?))   gf  (nil (gen-fragment '(3) '(3) x))   lrq (:length (length-rational-quantize x))   dyn (:velocity (velocity-to-dynamic x))   ls  (nil (length-span '(6/4 6/4) x))   ob  (:pitch (ambitus 'oboe x))   bn  (:pitch (ambitus 'bassoon x))   hn  (:pitch (ambitus 'french-horn x))   )  
      Please note that the number of methods within an instance can be much bigger than in the example above.
       
      Two bars of omn - opusmodus notation
      (setf mat '((q d4 pp s eb4 < leg g4 < leg bb4 < leg a4 q. cs5 mf              -e 3q gs5 > leg fs5 > leg c5 > b4 > leg f4 leg e4)             (t d4 < leg eb4 < leg g4 < leg bb4 q. a4 marc              t fs4 mf leg gs4 leg e. c5 e b4 t f5 leg e5 leg d5 leg eb5              3q bb5 > a4 > bb5 > e a4 pp stacc -e)))  
      Applying methods:
      (setf t1 (unfold 'm2 7 mat) t2 (unfold 'm2 '(-12 var ob) mat) t3 (unfold 'm2 'var mat) t4 (unfold 'm2 '(-12 gf lrq ls dyn ret var hn) t3) t5 (unfold 'm2 '(gf lrq ls dyn bn) t2) )  
      The result with a Wind-Quintet layout:
      (ps 'gm :w5 (list t1 t2 t3 t4 t5))  

       
       
       
      BIND-TO-INTERVAL
       
      The function BIND-TO-INTERVAL will bind (connect) a series of lists (patterns) to each-other with the given interval. Each transposition value is the sum of the last pitch in the list plus the given interval. The result of the process is a start transposition value for the next list. If rotate and variant options are used, the rotate process is the first followed by variant and finally the start transposition.
       
      In the example below the last pitch in the first list is g4, with binding interval 1 (semitone), therefore the start transposition value of the next list is gs4:
      (bind-to-interval '(1) '((s c4 d4 e4 g4) (s c4 d4 g4 e4))) => ((s c4 d4 e4 g4) (s gs4 bb4 eb5 c5))  
      Examples:
      (setf pattern '((s c4 d4 e4 g4)                 (s c4 d4 g4 e4)                 (s g4 e4 c4 d4)                 (s c4 d4 f4 g4)                 (s c4 d4 g4 f4)                 (s g4 f4 c4 d4)                 (s c4 d4 g4 f4)                 (s g4 gb4 f4 g4)                 (s g4 gb4 f4 a4)                 (s d4 f4 g4 a4)                 (s a4 g4 f4 d4)                 (s d4 f4 g4 c5)))  
      In this example the binding intervals are 1 and 2 randomly selected:
      (bind-to-interval (rnd-sample (length pattern) '(1 2)) pattern) => ((s c4 d4 e4 g4) (s gs4 bb4 eb5 c5) (s d5 b4 g4 a4) (s b4 cs5 e5 fs5)     (s g5 a5 d6 c6) (s d6 c6 g5 a5) (s bb5 c6 f6 eb6) (s f6 e6 eb6 f6)     (s g6 fs6 f6 a6) (s bb6 cs7 eb7 f7) (s fs7 e7 d7 b6) (s cs7 e7 fs7 b7))  
      In the next example the binding intervals are 13 and -13 with random variant:
      (bind-to-interval (rnd-sample (length pattern) '(13 -13)) pattern :variant '?) => ((s c4 d4 e4 g4) (s fs3 a3 e3 d3) (s eb4 fs4 bb4 gs4) (s g3 f3 d3 c3)     (s b1 a1 e1 fs1) (s g2 f2 bb2 c3) (s b1 a1 d2 e2) (s eb1 eb1 d1 cs1)     (s d2 cs2 c2 e2) (s f3 d3 c3 bb2) (s b3 d4 e4 fs4) (s g5 bb5 c6 f6))  
      Here the binding intervals are 1, -1, 2 -2:
      (bind-to-interval '(1 -1 2 -1 2 -1 2) pattern) => ((s c4 d4 e4 g4) (s gs4 bb4 eb5 c5) (s b4 gs4 e4 fs4) (s gs4 bb4 cs5 eb5)     (s d5 e5 a5 g5) (s a5 g5 d5 e5) (s eb5 f5 bb5 gs5) (s bb5 a5 gs5 bb5)     (s b5 bb5 a5 cs6) (s c6 eb6 f6 g6) (s a6 g6 f6 d6) (s cs6 e6 fs6 b6)) (bind-to-interval '(1 -1 2 -1 2 -1 2) pattern :variant '?) => ((s c4 d4 e4 g4) (s gs4 f4 bb4 c5) (s b4 gs4 e4 fs4) (s gs4 bb4 cs5 eb5)     (s d5 c5 a4 g4) (s a4 g4 e4 d4) (s cs4 eb4 gs4 fs4) (s gs4 a4 bb4 gs4)     (s a4 bb4 b4 g4) (s fs4 a4 b4 cs5) (s eb5 c5 bb4 gs4) (s g4 e4 d4 a3))  
      Example with rotation:
      (bind-to-interval (rnd-sample (length pattern) '(1 2)) pattern                   :rotate '(1 2 1 2 1)) => ((s c4 d4 e4 g4) (s a4 f4 g4 c5) (s d5 e5 a5 fs5) (s gs5 cs5 eb5 fs5)     (s gs5 fs5 cs5 eb5) (s e5 a5 g5 d5) (s e5 b4 cs5 fs5) (s g5 a5 a5 gs5)     (s bb5 gs5 g5 fs5) (s g5 a5 d5 f5) (s g5 d6 c6 bb5) (s c6 d5 f5 g5))  
       
      PAN
       
      This function converts mixer panning values in the range from -100(L) to 100(R) into MIDI pan values. The centre position value in the PAN function is 0.
       
      Examples:
      (pan 0) => 64 (pan '(-12 0 12)) => (56 64 72) (pan '(-30 -10 10 30)) => (45 58 70 83)  
      PAN in DEF-SCORE instrument instants definition:
      (def-score SQ            (:title "String Quartet - VSL Show"             :key-signature 'chromatic             :time-signature (get-time-signature vln1)             :tempo tempo             :layout (string-quartet-layout                      'violin1 'violin2 'viola 'cello))      (violin1    :omn vln1    :port 0    :channel 1 :sound 'vsl-violin-solo    :program 0 :pan (pan -30))      (violin2    :omn vln2    :channel 2 :sound 'vsl-violin-solo    :program 0 :pan (pan -10))      (viola    :omn vla    :channel 3 :sound 'vsl-viola-solo    :program 0 :pan (pan 10))      (cello    :omn vlc    :channel 4 :sound 'vsl-cello-solo    :program patches-vc :pan (pan 30))   )  
      PAN in DEF-INSTRUMENT-SETS instance:
      :string-quartet   (:layout string-quartet-layout            :port nil            :channel '(1 2 3 4)            :sound 'gm            :program '(violin violin viola cello)            :controllers nil            :pan (pan '(-30 -10 10 30))            :volume 92)

      The upcoming release will allow you to open display-midi, display-musicxml, graphs and snippets in a separate window. For any of you using second monitor this will be great addition to your work flow.
       
      Examples:
      (display-midi 'score :display :window) (display-musicxml 'score :display :window)  
      Best,
