Newbie question - audio I/O's
by andrew 05 Oct '01

05 Oct '01

Hi, New to PD and trying to figure out if it currently supports more than one pair of input or outputs on NT/Win2k? (I'd run in on Linux but my soundcard isn't supported.) Having great fun so far but I can feel time slipping away as I get further into this thing.... ac

more mp3play~
by CK 05 Oct '01

hi, is there a way to get around the short audio dropout in mp3play~ when one player object is playing and another one is loading a file ? regards, x p.s.: will try to load a second (i.e.: mp3pl4y~.pd_linux) and see if the problem persists ... not tooo elegant though ... -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

Yes. Anything greater or less is undefined, although OpenGL usually clamps them out for you...

Do the values used in colorRGB have to be between 0 and 1? Thanks. regards, Rory. ____________________________________________________________ Do You Yahoo!? Get your free @yahoo.co.uk address at http://mail.yahoo.co.uk or your free @yahoo.ie address at http://mail.yahoo.ie

env~ and block~
by marius schebella 05 Oct '01

05 Oct '01

hi list, again I need help: pd crashes when I put an "env~"-object in a window witch a blocksize larger than 128. I know that env~ uses 256 samples by default and needs to be twice as large as the block size, but how can I set the value of env~. I use the first 0.34-version on windows. (i think this version crashes with every audio-error). marius.

RE: [PD] writing pd object in cpp
by Mark Danks 04 Oct '01

All of GEM is written in C++. If you look at some of the base classes (CPPExtern for example), you should see some good examples of how to make it work. It is pretty straightforward to get going. Later, Mark ============================ = mdanks(a)stormfront.com = Technical Director PS2 = http://www.danks.org/mark ============================ -----Original Message----- From: andychen5018 [mailto:andychen5018@hotmail.com] Sent: Wednesday, October 03, 2001 10:39 PM To: pd-list(a)iem.kug.ac.at Subject: [PD] writing pd object in cpp Hi, everyone, I am Andy. I have a project involving writing a pd object that acts as an interface to the touchpad driver. Basically the idea is to get coordinate data from touchpad and use it to create a better interface for pd. My touchpad is Synaptics, and it's device driver and API is open source and written in C++. So I am thinking that I will write the source file for my pd object in C++, because touchpad driver is in C++. But i am having all sort of problem just to get it compiled. Can someone please help?

Hi list, Just thought I'd report a success with PD. Last Sunday I did my first full show using PD (for about 80% of pieces being presented). No nasty surprises, everything worked fine and in a stable manner. It's fun to be able to hit the real world with it. That's all for now. ./MiS

MP3Play-- arguments...
by nullpointer 03 Oct '01

Hi All, The MP3Play object from IEMLIB Has anyone used it to control mp3 playback at different rates (can you speed up/slowdown) or by directly controlling the readpoint (and reading chunks granular style)?

MIDI/Linux

Hi I was wondering... Does PD/Linux require /dev/sequencer or does it use /dev/midiXX directly? TIA Soeren
