AFAIK pythonsound is basically dead.
This is the first message I've seen about it in a loooong time.
I have not used it in well over a year, and last
I heard Maurizio had given up on it in favor of CLM.
Maurizio, if you're reading this, is that true?

i think there is a bug here from PowerSegment in bpf.py:
if dict.has_key('periodic'):
periodic = dict['exp']
else:
periodic = 0
seems like it should be:
if dict.has_key('periodic'):
periodic = dict['periodic']
else:
periodic = 0
is omde still under development? i can commit these changes myself if
necessary, as i am still actively using and adding parameter gens from
omde to athenaCL.

hey all. much latter than i had hoped, i am finally working on wrapping some of omde/pmask's functionality in higher-level athenaCL parameter objects, as i mentioned some time ago. i am currently working with 'omde/random.py' and discovered an undefined name 'make'; i see the imports of 'make_function' and 'make_generator' from omde.functional. looking at the last cvs update for this file i see a notation that says 'make -> make_function'; can i assume that all calls to 'make' should be replaced by 'make_function'? thanks for any help here. ________________________________________ christopher ariza \ http://flexatone.net |

I have no more access to that server so I could not delete that site as I wish. The current version of OMDE/pmask is available ONLY from the pythonsound CVS and is REALLY different from the one you got. You should really get the CVS version and check what is changed. I'm sorry if this is source of problems. These days I'm going to release some tarballs since several people asked for them. Maurizio Umberto Puxeddu. |

thanks for your permission, and im glad you got a chance to check out the software. please feel free to send along comments, suggestions, or bug reports. also, please download a new version of athenaCL (or use cvs update): i fixed a mean bug yesterday. all versions have been updated, and there is a new chapter to the documentation covering textures. i too look forward to working on interopeability between the two packages as well. i dont quite understand OMDE yet, but i will certainly investigate it in the future. athenaCL needs python 2.1 or better. works fine in 2.2. i grabbed pmask version 0.12 off of your site. perhaps it looked odd because i left out some files: output.py, pitch.py, povray.py, precision.py, scales, and score.py. this may be a mistake, but my original plan was not to included the complete pmask package, as i only need Generator subclasses. These objects will be wrapped in an object in athenaCL and integrated into athenaCL's argument checking and texture system. i cant use pmask score, scale, or pitch data-structures (yet?) as athenaCL already has different implentations of these features tied closely to the pitch model and the UI. however, for the sake of giving users all the tools possible, and if you prefer, i could just as well include the entire pmask package. my intuition is that most users would rather have a separate copy of pmask for pmask work, even if one is included within the athenaCL directory. what do you think? my goal is to have pmask Generators available from within athenaCL by version 1.1. the next release, 1.0.14, will include pmask files, though they are not yet tied to anything in athenaCL. i likely will not get to version 1.1 until early may. ____________________ christopher ariza http://flexatone.com On Sun, 3 Mar 2002, Maurizio Umberto Puxeddu wrote: > On Wed, 27 Feb 2002, christopher ariza wrote: > > > > > hi Maurizio. i talked to you sometime ago about my python/csound project > > called athenaCL. i have been hacking away, and now (after basically > > redesigning most of the code) i am at the point where i can easily begin > > to add many parameter operators for use within my software. cmask/pmask > > provides exactly the kind of library of operators i will need, and i would > > like to ask permission to include a number of pmask files (within a pmask > > directory) with athenaCL. since we both use the GPL, i cant imagine that > > this will bei a problem. i will of course provide the proper > > acknowledgements and any other information you think necessary. i am also > > contacting Hans Mikelson for permission to use chaos.py, and Andre > > Bartetzki for cmask in general. > > Of course no problems by my side. > > > my goal with athenaCL is to create an agorithmic composition environment > > that is based on a user friendly, interactive command line interface; > > rather than writting code that you run to make scores (like cmask/pmask), > > athenaCL is an application that lets you browse your settings, checks > > errors, and perform global edits. in this way i think pmask and athenaCL > > each fill a particular niche. > > I'm happy to hear that.

I'm happy to hear that. I experimented a bit with AthenaCL. Obviously we got different views about UI but AthenaCL is very interesting. I hope this operation will also enable accessing AthenaCL features from OMDE/pmask.

hi Maurizio. i talked to you sometime ago about my python/csound project called athenaCL. i have been hacking away, and now (after basically redesigning most of the code) i am at the point where i can easily begin to add many parameter operators for use within my software. cmask/pmask provides exactly the kind of library of operators i will need, and i would like to ask permission to include a number of pmask files (within a pmask directory) with athenaCL. since we both use the GPL, i cant imagine that this will be a problem. i will of course provide the proper acknowledgements and any other information you think necessary. i am also contacting Hans Mikelson for permission to use chaos.py, and Andre Bartetzki for cmask in general. my goal with athenaCL is to create an agorithmic composition environment that is based on a user friendly, interactive command line interface; rather than writting code that you run to make scores (like cmask/pmask), athenaCL is an application that lets you browse your settings, checks errors, and perform global edits. in this way i think pmask and athenaCL each fill a particular niche. the files i would like to include are these: accumulator.py bpf.py chaos.py generator.py list.py mask.py oscillator.py quantizer.py range.py rng.py segment.py none of this is yet integrated into my software: it will be a month or so before that happens. for more information on athenaCL visit: http://www.flexatone.com/athenacl thanks! ____________________ christopher ariza http://flexatone.com |

hello. pythonsound is an attempt to use the same language (python) to describe both orchestra and score of a composition. it should be considered just a proof of concept: it is 67 times slower than csound at the moment. the obvious next step is trying to load the csound opcode and use them instead of the pure-python opcodes. you can find it in the pythonsound directory. if you want to run it, you'll need python 2.2 beta and the numeric python package. maurizio umberto puxeddu. |

Hello. I'm about to make a first pre-release package. Most changes today are related to this. In particular I had to add an extension to all executable scripts (like utilities). I don't like them and don't need them under Linux but they make life easier to Windows and MacOs people. Also I moved the database files out from the omde directory into the data directory. python setup.py sdist --formats=gztar,zip should build source packages in the dist directory. I will not put the packages on the web, it's for old time pmask users that want to see what's happened and I'll send it on demand. Maurizio Umberto Puxeddu. |

Hello Paul. OMDE oscillators function were broken for non-constant frequency values. For this reason, temporarily, they work with constant frequencies. The problem is due to the main difference between Cmask and pmask algorithms. In Pmask the interpreter has total control on time flow. The author is always sure that if t2 > t1 he will never evaluate a generator at t1 after he evaluated it at t2. Hence he can pick a reasonable small dt and integrate all functions by this step. OMDE functions can be evaluate randomly so, in theory, each time I want the value of an oscillator at some time t1, I have to calculate its phase at t1, integrating the phase value from the beginning. Do you know any better method? Of course I could add some phase value caching and speed up things in most of the cases (most of the times, using pmask algorithms, the things work just like with Cmask)... Any ideas?

http://www.flexatone.com/athena.html "AthenaCL is an open-source, cross-platform, command-line program that functions as both a set-class theory utility and as an object-orientated, Python-scriptable algorithmic front-end to Csound. Combining these features allows rapid and flexible scoring of Csound instruments with the elegance of Python-written texture algorithms. These simple algorithms allow the organization of pitch-materials by ordered content-groups, employing modern 12-tone set-class and pitch-class notations. Rather than writing its own music, AthenaCL is a compositional assistant: the algorithms create complex textural surfaces, leaving the limitless mixture and placement of these textures and their attributes entirely in the hands of the composer." It's GPL'd and I'd like to have it inside OMDE/pmask in someway... OMDE/pmask/Athena... well maybe a new name. We could have everything related to Python and composition in the same project. But I'd like to have an more precise idea of the feasibility of this fusion before I contact the author. Could you be interested in exploring this option? Maurizio Umberto Puxeddu. |

Well. The INSTALL file is meant to be read by people installing tarballs. Most recent pmask tarball used to include the scala database so there is non need to do that. If you build a source package with the setup script it should include binary database. You could include it in "special instruction for people using CVS".
