Communicating with Pd
by Pierre Massat 03 Sep '12

03 Sep '12

Dear List, I would like to know whether it is possible to communicate with an instance of Pd from a bash or a python script (things like sending control values to specific [receive] objects), or any other program actually. I guess I could do this with LibPd, but I'd rather stick to plain Pd right now if possible. Cheers, Pierre.

pd unable to connect to JACK server
by Dix 03 Sep '12

03 Sep '12

Good evening, I am trying to get pd to work on my eeepc 1000H netbook, which is running Ubuntu 12.04 and using an HDA Intel sound card. pd keeps giving me this message when I try to connect to jack: JACK: unable to connect to JACK server JACK: server returned status 17 I tried qjackctl: in the gui, I started jack and pressed play. Still pd was unable to connect to jack. I also tried 1) changing sample rate to 48000, 2) unchecking realtime in jack settings. Finally I got tired of googling and thus decided to send out this cry for help before going to bed. looking forward to some answers/questions/ideas, thanks, Dix

Re: [PD] pointcloud in Gem (timbreID) and performance

In processing theres a library called glgraphics that allows to use vertex arrays,this allow to calculate vertices in the gpu and it is very fast, i can draw up to 80 000 vertices in my computer. Is it possible something like this in pd? Is it possible to access to vertex arrays commands from pure opengls from gem? any idea?
