Mystery surrounds jit.ameba.

From earlier (Max 5)  Cycling 74 documentation https://docs.cycling74.com/max5/refpages/jit-ref/jit.ameba.html:

“The jit.ameba object began life as a completely failed attempt at a linear interpolation object. As the Oblique Strategies say, “Honor thy error as a hidden intention.” If you’re interested in linear interpolation objects, try the jit.plur object. Otherwise, please enjoy the mess.”

Horizontal and vertical quantization

What actually does that mean?

From Peter Elsea

“This is a pixilation (resampling) trick. The help file admits this was supposed to be something else, but didn’t work. Needs a spell check too, but pretty interesting. ”

Using the text processing example I built a 4th order Markov chain for “The Cat in The Hat” (by Dr. Seuss). Here is some of the result (it continues to infinity) with indentation added for readability:

The sat the sun is not shine.
It was to Sit! Sit!
And I sat in the house
All that?

How I wish We had something went BUMP! How I wish We did not shine.
It was to us jump! We looked!
The Cat in that cold to go out And wet to play.
So all we sat in the Hat! And he saw him!

Then we sat is wet to Sit! Sit!
And to go out
And the house
All that?

Why do was too wet And there little bit. And wet to go out
And there we saw him step in on that?
How I wish We sat is nothing at all.
So all we could do was too wet day.

So all we sat the house 
All that is fun there we can have Lots of good fun the mat!
We had something at all.
So wet to go out And the sun is wet to Sit! Sit!

And I said too wet to do I know it is not sunny!
Too we can have Lots of good funny!
Too wet And I sat is fun the house. We sat the house. We saw him!
The Cat is wet to us.

The help file patch allows real time Midi improvisation with a step sequencer style of playback:

Short lessons on the topic of algorithmic composition.

By Christopher Dobrian

http://algocomp.blogspot.com

“… A blog of short lessons on the topic of algorithmic composition — the use of formal systems to generate music (and, by extension, other types of time-based art) with computer programs. The examples in these lessons are provided in the form of Max programs.”

Probability based drum machine

Step sequencer in Max with probability based decisions for each instrument.

The Max patch is not available. Here is a link to a patch that shows how the probability engine probably works: http://reactivemusic.net/?p=18909

SSTV in Max

Slow scan television simulation using Jitter.

See this Cycling 74 forum post for an explanation of how frame rate is limited by audio sample rate and  horizontal resolution: https://cycling74.com/forums/topic/jit-poke-vertical-bars-at-high-scan-frequencies/

Folder: sstv

Patches:

  • raster-scan4.maxpat (original)
  • raster-scan5.maxpat (better frame rate by lowering screen resolution to 160 x 120)
  • raster-poly-wrap5.maxpat (even better frame rate – up to 15 fps – by up sampling to 384 KHz)

Note – set your audio sample rate to 96KHz if possible, to get the results described above.
