  15. On my setup it sounds better if I don't have too many notes going off on the same beat. Try: http://earslap.com/projectslab/otomata/?q=0o1l2a3t584x6v72 to see what I mean

  21. http://earslap.com/projectslab/otomata/?q=2e3e4e5e6e7u8s8h8z... Making things not only auditory appealing but visually appealing also. This one has some interesting patterns.

  22. If the grid is numbered 1 2 3 4 5 6 7 8 9 10 11 12 ...

  23. http://earslap.com/projectslab/otomata/?q=8g804u08022p4q4s I like this one because the two left-right components switch the period of the beat on the 5th and 9th rows (themselves also alternating pitch and period) while not breaking the base beat. I do with the "make link" would let you 'bookmark' a phase: the way it started out went through some cool sequences before stabilizing into this.

  24. A surprisingly short loop: http://earslap.com/projectslab/otomata/?q=3z3o43503s and some lame attempt at "chaos": http://earslap.com/projectslab/otomata/?q=1h4o2n (though of course these are just finite state machines and they all loop eventually)

  25. 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=04046g043q515p3...

  29. 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=0q1q2q3q8w8y8p8...
