Continuous Signals

Signals are patterns with continuous values, meaning they have theoretically infinite steps. They can provide streams of numbers that can be sampled at discrete points in time.

saw

A sawtooth signal between 0 and 1.

    note("<c3 [eb3,g3] g2 [g3,bb3]>*8")
.clip(saw.slow(2))
    n(saw.range(0,8).segment(8))
.scale('C major')

    sine

    A sine signal between 0 and 1.

      n(sine.segment(16).range(0,15))
.scale("C:minor")

      cosine

      A cosine signal between 0 and 1.

        n(stack(sine,cosine).segment(16).range(0,15))
.scale("C:minor")

        tri

        A triangle signal between 0 and 1.

          n(tri.segment(8).range(0,7)).scale("C:minor")

          square

          A square signal between 0 and 1.

            n(square.segment(4).range(0,7)).scale("C:minor")

            rand

            A continuous pattern of random numbers, between 0 and 1.

              // randomly change the cutoff
s("bd*4,hh*8").cutoff(rand.range(500,8000))

              Ranges from -1 to 1

              There is also saw2, sine2, cosine2, tri2, square2 and rand2 which have a range from -1 to 1!

              perlin

              Generates a continuous pattern of perlin noise, in the range 0..1.

                // randomly change the cutoff
s("bd*4,hh*8").cutoff(perlin.range(500,8000))

                irand

                A continuous pattern of random integers, between 0 and n-1.

                • n (number): max value (exclusive)
                // randomly select scale notes from 0 - 7 (= C to C)
n(irand(8)).struct("x x*2 x x*3").scale("C:minor")

                brand

                A continuous pattern of 0 or 1 (binary random)

                  s("hh*10").pan(brand)

                  brandBy

                  A continuous pattern of 0 or 1 (binary random), with a probability for the value being 1

                  • probability (number): a number between 0 and 1
                  s("hh*10").pan(brandBy(0.2))
