This is a really great project! Here's one that I made: http://www.earslap.com/projectslab/otomata?q=1n204g7b7b6x6q4u http://www.earslap.com/projectslab/otomata?q=1n204g7b7b6x6q4...

This seems like a great idea for background music for a game. Repetition shouldn't be a problem at least.

    Indeed. Another fascinating approach to generative music is to code it out, and add some randomness, like this guy who does a pretty good stab at imitating Keith Jarrett: http://homepage.mac.com/digego/study_in_keith.mov http://homepage.mac.com/digego/study_in_keith.mov (25MB mov file) This really shouldn't have the problem of repetition. You even make events in the game affect the music, to make it less monotone, and add to the mood of the game. It has been tried, but as far as I know no one has actually published something like this yet.

      > You even make events in the game affect the music This is really what makes it _very_ interesting in my opinion. The whole super compressed non-looping music is nice, but having music that responds to your actions in real time can be amazing. More than having music for each level you can have music for each bad guy and even better how the bad guy is "feeling". Speed up the sequencer when they are mad. Start out with a bunch of cells and remove them as a way of showing the health left.

  Using cellular automata to generate music may not be new, but I haven't seen this specific method used. Nor have I seen anything that compares to the way it subtly changes as it develops while still maintaining a steady beat without resorting to resetting the pattern as in your example. (Correct me if I am wrong though; I'm not a musician.)

    This is the classic one from 1990 I believe: http://tamw.atari-users.net/camus.htm http://tamw.atari-users.net/camus.htm I do think the one linked in this post is a particularly nice one, and yeah the way it develops while maintaining a beat I think is fairly unusual.
wbhart 15y ago
Amazing. It would be really cool to be able to change the number of rows and columns and also the instruments and tones/chords for each row/column. It's fun opening more than one browser tab and having more than one of these going at once. I refer you to my comment about needing to be able to change the instruments.

  The problem I have with WolframTones is it tries too hard to sound like traditional human music and fails pretty badly at it. Procedurally generated music systems that don't attempt to emulate previous kinds of music fare far better (including the original link). An older example would be the original drum machines and keyboard synthesizers -- they were originally meant to function as affordable replacements for real instruments (a drum kit, piano or string quartet) and sounded pretty terrible when used in that fashion. Only when people started viewing them as instruments in their own right did they work well (and create previously unheard sounds and genres in the process).

This is quite fun to play around with! Many of the other CA-based music generators I've seen have sounded rather atonal and random compared to this one. Here's one I made using symmetric initial conditions (doing this makes for somewhat interesting visual patterns as well): http://www.earslap.com/projectslab/otomata?q=0q1q2q3q8w8y8p8f887868580905010b4y5y6y7l7v701j1d1o4535253a6h5n2c http://www.earslap.com/projectslab/otomata?q=0q1q2q3q8w8y8p8...

    That one is excellent - visually as well as auditorily pleasing. In terms of interesting evolution I keep coming back to this one I just sort of randomly put together: http://www.earslap.com/projectslab/otomata?q=04046g043q515p3j132x647t http://www.earslap.com/projectslab/otomata?q=04046g043q515p3...
- jerf 15y ago
  That's partially the result of the chosen scale. Run a set of "up" arrows from the top left to the lower right and it will play the scale. Then go back to just playing around, and you'll hear how that choice colors the results. A different scale choice would have different results. This would combine well with bajsejohannes's idea; you could exert some control over the scale while letting the automata run free.

Starting working on a JS version so I can use it on an iPad. It's pretty rough right now, but on its way. Need to add in the html5 audio and more complete collision detection. http://www.zmitri.com/static/automataJS.html http://www.zmitri.com/static/automataJS.html

It's working decently now, same link as above, if you'd like to try it out.

I built a table of the Y, the X are just 0 indexed numbers ^>v< 0 qwer 1 tyui 2 opas 3 dfgh 4 jklz 5 xcvb 6 nm01 7 2345 8 6789
