LOCO-SONNET, a graphical composition system

SUMMARY

Musical object creation

• NOTE duration pitch velocity]
  A note with given duration (in time-units), pitch (in MIDI
  numbers), and intensity (between 0 and 1)
  
• REST duration
  A rest (silence) lasting duration time-units
  
• S object1 ... objectn
  A S(equence) of objects starting one after another
  
• P object1 ... objectn
  A P(arallel) structure of objects starting at the same time
  
• PRE object
  A prefix object
  
• POST object
  A postfix object
  

Choice systems of the micro world 'Composing is making musical choices'

• ALEATORIC list-of-possibilities
  Returns a randomly chosen element from the list of possibilities
  List-of-possibilities is evaluated each time the module is called
• COLLECT source number
  Returns a list of number values from source
  Source is evaluated a number of times per call the module
  Number is evaluated each time the module is called
• CONSTANT value
  Returns value
  List-of-possibilities is evaluated each time the module is called
  
• CUMULATIVE increment start-value
  Each new value that the module will return is increment larger than the
  previously returned value. The first value returned is the start-value
  Increment is evaluated each time the module is called
  Start-value is evaluated at the first time the module is called
  
• SELECTED selection input1 .. inputn
  Returns a value from one of its inputs, according to selection
  Source is evaluated each time the module is called
  One of the inputs is evaluated each time the module is called
  
• ITERATED source number
  The module will repeatedly return a value from source a number of times
  Source is evaluated once per a number of calls of the module
  Number is evaluated once per a number of calls
  
• ORDERED list-of-possibilities
  Returns one of the possibilities in the given order
  List-of-possibilities is evaluated when all the elements are used
  
• SCALE minimum maximum resolution
  Returns a list of values between minimum and maximum
  with the given resolution
  Minimum, maximum, and resolution are evaluated each time the module is called
  
• SERIAL list-of-possibilities
  Returns one of the possibilities, excluding it in future
  choices, until all are chosen. Then it starts all over again with the full
  list of possibilities
  List-of-possibilities is evaluated when all elements are used
  
• REMEMBERED in start
  Returns its previous input. The first result is start
  Start is evaluated only the first time the module is called
  In is evaluated every time the module is called
  
• TRANSLATED source list-of-original-translation-pairs
  Returns a value from source translated according to the
  table (list-of-original-translation-pairs)
  Source is evaluated each time the module is called
  List-of-original-translation-pairs is evaluated each time the module is called
  
• WEIGHTED list-of-possibility-probability-pairs
  Returns one of the possibilities according to the assigned probabilities
  List-of-possibility-probability-pairs is evaluated each time the module is called
