Video from my first session with the Raspberry Pi running Pure Data. I'm running Pd 0.44 (test version) with "-nogui -noadc -alsa" flags + a budget USB audio device, and a Novation ReMOTE ZeroSL as the midi device. Raspberry Pi OS is Raspbian “wheezy.” Note, I'm running from the command line, not from inside the X window system (performance with GUI seems more likely to glitch, at least with my first tests). I did not try headphone jack for audio given initial reports were not good (and presently I'm unable to test HDMI audio).
Pd 0.44 here: pure-data.git.sourceforge.net/git/gitweb-index.cgi
I used notes from Miller Puckette sent to the Pd-list (check September 8 & 9, 2012) and some info. from log.liminastudio.com/programming/running-puredata-on-the-raspberry-pi to get things going.
