blubb 0.0

instrument device

Sounds and looks like bubbly water drops.

Basic function:

  • circles are drawn with x=sin(t), y=cos(t)
  • pitch & volume envelopes for short sound with increasing frequency
  • jump to random position after each drop by adding a random offset to x and y
  • automatic random sequencer (4ever)

boing 1.1

instrument device

Draws a bouncy ball on an oscilloscope

Basic function:

  • a circle is drawn in the horizontal plane
  • circle is moved along y-axis to form a spiral
  • width is altered to shape the spiral like a ball
  • jumps by adding offset and changing size
  • envelopes & LFOs for spiral density, rotation, 3D depth, jumps, etc.

fractal spiral 1.8

instrument device

Draws a fractal spiral with infinite zoom

Basic function:

  • draws a circle, which is moved along a line to form a spiral
  • the line is also shaped like a spiral
  • seamless zooming by blending over to the next spiral stage
  • envelopes & LFOs for spiral density, width, rotation, zoom, 3D depth, etc.

Kepler-Bouwkamp 0.4

instrument device

Draws polygons and circles into each other.

Basic function:

Used in: Lines

line horizon 0.1

instrument device

Draws a horizon of lines with a nice overtones and a square minecraft sunrise.

Basic function:

  • draws an array of horizontal lines
  • moves lines above 0 upwards and below 0 downwards (beat synced)
  • function for vertical distribution so that lines around 0 are closer together (bow)
  • function to squeeze lines around 0 horizontally, to make them appear shorter / further away (squeez)
  • split the lines vertically in the middle and move a circle in between them (sunrise)
  • clip circle to become a square (shape)

Used in: Lines

mushrooms 0.3

instrument device

A patch to draw mushrooms on an oscilloscope with sound.

Basic function:

  • draws a circle with x=sin(t), y=cos(t)
  • different volume on both channels to form an ellipse
  • moves it along a vertical line to turn it into a spiral
  • change width to shape it like a mushroom's stem and head
  • some bending options to make it look like several rotating mushrooms

Used in: How To Draw Mushrooms On An Oscilloscope With Sound, Shrooms

Nyquist-Shannon 0.1

instrument device

A demonstration of sampling rate and aliasing.

Basic function:

  • draws a sine wave and shows the points that would be sampled at a certain sampling rate (doesn't actually change the sampling rate)
  • phase shift to show that the sampled signal can differ, depending on it's timing
  • aliasing artifacts: shows a possible different interpretation of the same sample points
  • just a demonstration tool, not really meant to be a synthesizer

Used in: Tutorial 2

Oscilloscope 2.0

audio device

A lissajous oscilloscope

Basic function:

  • based on a Max patch I found, but forgot where (credits to the unknown creator!)
  • uses one audio channel for horizontal deflection and the other one for vertical deflection
  • different drawing modes and colors
  • doesn't look very realistic, but works well for preview

Used in: Max patches overview video 2015

No demonstration video available, but here's an example where the patch (or a similar one) was used:

radar 1.3

instrument device

Draws all kinds of spirals, tunnels, radar screens, etc. on an oscilloscope with sound, and can even do kickdrums.

Basic function:

  • draws a circle
  • moves circle along a line to form a spiral
  • various phasing options to change the spirals direction and shape
  • 3D rotation and bending and fading effects
  • various trigger modes for different types of sounds
  • overall a bit complicated, but very versatile and also has presets

Used in: Spirals

sincos 4001

instrument device

Simple lissajous patterns

Basic function:

  • draws circles with x=sin(t), y=cos(t)
  • circles for harmonic frequencies with f(harmonic)=f(circle)*N
  • combinations of up to 8 harmonics (additive synthesis)
  • volume randomizer for harmonics
  • fine frequency control for moving patterns
  • relatively complicated and CPU intensive patch for a relatively simple task (it was my first M4L patch)

Used in: Nuclear Black Noise (similar Pd patch), live sets

No demonstration video available, but here's an example where the patch (or a similar one) was used:

sincos demo 0.2

instrument device

A patch to demonstrate the correlation between sine and cosine on a unit circle.

Basic function:

  • draws a unit circle
  • highlights a point that moves along the circle
  • draws a triangle with a line from the center to the point (hypotenuse) and the sine and cosine values (catheti)
  • zoom out to see the resulting waveforms
  • rotate cosine waveform to see the phase correlation better

Used in: Tutorial 2

starfield simulation 2.0

instrument device

Starfield simulation screensaver for your oscilloscope

Basic function:

  • sounds wonderfully awful and sometimes does unpredictable things
  • draws stars (dots) at random positions and moves them outwards to appear like flying through a starfield
  • each star gets parameters "pitch" and "godspeed" which determine it's time and outward moving speed
  • after the time is up, the next star is drawn
  • when stars move out of scope they reappear at a new random position
  • some stars are spirals or smiley faces

Used in: Asteroids

text 0.1

instrument device

A patch that writes text on an oscilloscope with sound

Basic function:

  • text input with up to 12 letters
  • each letter is drawn by a function that represents it's shape mathematically
  • possible characters: A...Z, 0...9, )
  • ")" draws wholesomely smiling face

Used in: Asteroids, Kickstarter Video 2015
