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)

instrument device

Draws a bouncy ball on an oscilloscope
Basic function:
 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

A patch to draw a butterfly on an oscilloscope with sound.
Basic function:
Used in: Shrooms


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.
Used in: Spirals


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

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
