CC3 Week 2 - Introduction To SuperCollider II

This week's exercise was way too hard for only week two.

// ONE

(
z = { arg freq;
 f = if ( 
   freq == 440, // Set Concert A
   { "Frequency is Concert A" }, // If the input freq is equal to Concert A
   { g = if (    
     freq < 440,   // If the input freq is less than 440
     { "below Concert A" }, // "below Concert A" is added to "Frequency is"
     { "above Concert A" } // or else "above Concert A" is added to it.
     );
     ("Frequency is"+g) // Sentence beginning
   } 
  );
 }
)

(
a = z.value(440); // Input frequency
a.postln;
)



//TWO

(
z = { arg freq;
 f = if ( 
   freq == 440, // Set Concert A
   { "Frequency is Concert A, 440Hz." }, // If the input freq is equal to Concert A
   { i = freq - 440;     // i = Frequency deviation
     g = if (    
      freq < 440,   // If the input freq is less than 440
      { "below Concert A," }, // "below Concert A" is added to "Frequency is"
      { "above Concert A, +" } // or else "above Concert A" is added to it.
      );
     ("Frequency is"+g+i+"Hz.") // Sentence beginning +below/above +deviation
   } 
  );
 }
)

(
a = z.value(440); // Input frequency
a.postln;
)



//THREE

(
f = {
 arg freq, list;
 var i=1;
 while (
   { i <= list },  // While i is less than list,
   {
   (freq*i).postln; // Multiply freq by i and
   i = i + 1;   // add 1 to i.
   }
  );
 }
)

(
z = f.value(440, 10);
z.postln;
)



//FOUR

(
f = {
 arg  inputFreq, arraySize; // Defining inputs
 var overTones = Array.new(arraySize); // Creating array
 for (
  0,  // Start of array
  arraySize, // End of array
  { arg i; overTones = overTones.add((i+1) * inputFreq);} // Add i+1*input frequency to array
  ); 
 overTones; // Set array
 };
)

(
h = f.value(221, 6); // Input frequency and array size.
h.postln;
)



//FIVE

(
f = {
 arg  inputFreq, arraySize; // Defining inputs
 var overTones = Array.new(arraySize); // Creating array
 forBy (
  1,  // Start of array
  arraySize*2, // End of array
  2, // Step size
  { arg i; overTones = overTones.add((i+1) * inputFreq);} // Add i+1*input frequency to array
  ); 
 overTones; // Set array
 };
)

(
h = f.value(221, 5); // Input frequency and array size.
h.postln;
)



//6IX

( 
f = { arg drum;
 var x=drum;
 switch(x, 
  "kick", {"MIDI Note 1"}, // When a drum name is entered
  "snare", {"MIDI Note 2"},// an associated number is printed.
  "hihat", {"MIDI Note 3"},
  "crash", {"MIDI Note 4"},
  "ride", {"MIDI Note 5"},
  "tom", {"MIDI Note 6"}
  ) 
 }
) 

(
h = f.value("tom"); // Drum name
h.postln;
)



//SEVEN

(
f = { arg drum;
 var x=drum%12; // MIDI note value pitch class is determined.
 switch(x, 
  1, {"Kick"}, // Pitch class is converted into instrument.
  2, {"Snare"},
  3, {"Hihat"},
  4, {"Crash"},
  5, {"Ride"},
  6, {"Tom"}
  ) 
 }
) 

(
h = f.value(17); //MIDI note value
h.postln;
)
