[PD] stereo in pd

[shift8]

as sciss says, you can use soundfiler and:

[read -resize $1 array1 array2{  

(bunch of other nifty options for sample loading here too - see the help
patch for soundfiler.)

some limitations are: 
a) if the file is mono, only array1 is populated (sometimes annoying...)

b) the max resize is 4000000 samples because of what i would call a bug
in array index handling. you can change this in the source, but seem
like that introduces sound artifacts for some reason (search the pd-list
archive for 4000000 in message bodies for more info)

c) full on dsp stoppage during the file read.  not cool for performance
work.

i personaly strive for synthesis-only work, and use samples of small
duration for loops.  but that's just me wanking :)

i'd love to here what the state of the state is for threaded soundfilers
these days and best practices for this from the local ninjas!
