I did managed to run puredata on a beagleboard clone (igepv2) the audio IC on the beagle and clones is really bad, but with an external USB interface it works very well. I did tried a pitchshifter patch and ot worked. Better yet is to use LibPd. I also tried it using a puthon wrapper, amazing and super low resources.
Only problem. The ARM processors are diferent so you will need tocompile lots of externals from scratch. (Unless pd - extended start to have an ARM build system.
