instrument device

Sounds and looks like bubbly water drops.
Basic function:
 circles are drawn with x=sin(t), y=cos(t)

 a circle is drawn in the horizontal plane
 circle is moved along yaxis 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.

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.

instrument device

Draws polygons and circles into each other.
Basic function:
Used in: Lines


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


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


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


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:

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


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:

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


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


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


instrument device

A patch that draws circles and f̶o̶r̶m̶a̶t̶i̶o̶n̶s̶ ̶o̶f̶ ̶c̶i̶r̶c̶l̶e̶s̶ FiDgEt sPiNnErS
Basic function:
 draws a circle with x=sin(t), y=cos(t)
