delay @ OSX
by Thomas Grill 20 Nov '02

20 Nov '02

Hi all, i don't know if this has already been discussed, but it seems that the delay object doesn't work under PD 0.35 @ OSX. It just passes through the bang without delaying it. Don't know about 0.36 greetings, Thomas

CVS or not CVS ??
by Yves Degoyon 19 Nov '02

19 Nov '02

hi, i've got this dilemna right now : i agree for distributing my externals with Demudi but i'd rather not store them in the CVS repository.. why? hum, i don't want to support objects which have been modified without a prior agreement and a code review, leaving them in CVS is letting the things go that way... i'd rather not. cheers, sevy/yves

real-time sampler
by matthew jones 19 Nov '02

19 Nov '02

Hi, being new to Pd I would well appreciate any source for a real-time sampler/looper that anyone has lying around. The kind of thing that records until it receives a (say MIDI) message, then loops that buffer. or any suggestions. or jokes. but no hoax cheers!

Gem "model" object
by Dupras, Martin 18 Nov '02

18 Nov '02

Hi, For some project that I'm working on, I am using models loaded in the model object of gem. I'm not a programmer myself, so sorry if the question is naive. In principle, would it be possible to modify the code to the model object so that the actual vertices of a model can be moved? I have to investigate the feasability of this project, so any help with the above question would be greatly appreciated. Thanks. - martin

Rect -> Polar, Cube -> Spherical
by bbogart＠ryerson.ca 18 Nov '02

18 Nov '02

Would anyone be interested in PD objects that convert to/from these coordinate systems? I'm using a lot in my current project and will make them into objects if others would be interested. (Would there be any performance difference between an object and multiple exprs?) Thanks Ben
