Subject description: HexAtom |

Am about a third of the way through the recordings in this thread, and loving it so far. Thanks for posting.
My contribution is a MOV video over on FB that I posted this morning. I tried converting to MPEG2 using Adobe Premier Pro, but it drops the right audio channel no matter what I do, so I gave up. You may need Quicktime to view it.
This is the current version of this HexAtom software using built-in Java library soft synths that I started using with Scrabble-to-MIDI back in 2009. For NYE2014-15 I plan to use this approach with AAS physical modeling soft synths, haven't started working on the patches yet. The genesis of this approach goes back to the chess-to-just-intonation music that my son Jeremy & I performed in the NYE2007-08 webcast, which really took off after our discussion here of the Glass Bead Game.
The current state of HexAtom in the video is that the graphical atoms in the cellular automaton generate MIDI (the original mode of HexAtom), and also the generated MIDI notes generate and/or destroy graphical atoms. The latter part is new as of last summer. I used that at electro-music 2014, and am expanding it as I get time. Thus there is a feedback loop between graphical and MIDI audio domains.
Here is the jython patch used to automate this particular performance, which I wrote this morning

# module nye201415 for New Year's Eve 2014-2015 practice and performance
# D. Parson, December 2014
from javax.swing import Timer
from java.awt.event import ActionListener
import types
class TimedNoodleStateMachine(ActionListener):
'''
This is a noodle driver that goes off every 30 seconds
and update the state of the HexAtom universe. We cannot put
a sleep in the main event loop -- it blocks the GUI event
thread -- so TimedNoodleStateMachine uses a javax Timer to time
the cmds passed to the constructor.
'''
def __init__(self, cmds, interp, ms, invokeFirst=True):
'''
Initialize the state of this ActionListener state machine.
Parameter *cmds* is a sequence (list or tuple) of commands,
OR a Python generator of commands. The sequence can contain,
or the generator can generate, eother individual commands as
strings, or can contain/generate sequences of commands in the
for of subsequences of string commands.
Parameter *interp* is the interpreter for the set of commands.
Parameter *ms* is the number of milliseconds between invocations.
Parameter *invokeFirst* if True (default) runs the first command
sequence immediately, before starting the timer.
'''
self.cmds = cmds
self.interp = interp
self.ms = ms
self.timer = Timer(ms, self)
if invokeFirst:
self.actionPerformed(None)
self.timer.start()
def actionPerformed(self, event):
'''

'''
cmdseq = None
if isinstance(self.cmds, types.GeneratorType):
try:
cmdseq = self.cmds.next()
except StopIteration:
self.timer.stop()
return
elif len(self.cmds) > 0:
cmdseq = self.cmds[0]
self.cmds = self.cmds[1:]
else:
self.timer.stop()

the plumbing.
The *interp* parameter is the jython command interpreter object.
The *ms* parameter is number of milliseconds between advancing the

This function returns the reference to the TimedNoodleStateMachine

The pvf commands relate strongly to the feedback The probability of vacuum fluctuation value at the beginning of .077050 means that when a MIDI note feeds back into the cellular automaton (CA), there is a 70% probability (the third & fourth digits) that it will generate a new atom 7 semitones (the .07 -- affects color and MIDI pitch) above its original MIDI note, and a 50% probability that it will absorb the original atom. the 70-50 ratio is regenerative feedback. The later pvf12=.074070 (the 12 just means apply it to all 12 atomic numbers) makes this a degenerative 40%-70% ratio, and the final 10%-90% ratio kills the piece. Other transforms in the above rows change diameter of the space, skew and center of rotation of the atoms, and other properties of the CA.
I am posting an MP3 for completeness, although watching the video in HD is the thing to do. I have also posted a screenshot of the CA-to-MIDI mapping GUI, which I didn't touch at all after starting the noodle.

Thanks, Jack!
Michael, I'll give you a demo next June in the planetarium.

Loving this! Nice job, blairr.
FWIW. Anyone who wants their track included on the Noodles Comp Album (see here: https://auralfilms.bandcamp.com/album/noodles) should include a FLAC file with their post. Optionally, I can convert your MP3 file if you prefer. Just let me know.

Listened to this at work today, and then had no time to type here ... I loved it!

Thanks! I enjoyed putting this together, after a while it started to evolve in ways I hadn't anticipated, which is always a nice surprise.
Jack; I will PM you a link to the .FLAC file for the comp.
Cheers
