Hi Evan,
one big issue i'm having is that you can't load audio files into arrays without having the whole system pause for the new file to load. In fact, any time I change an array, the whole system pauses. is that because of lag, or because the arrays aren't multi-threaded? the writesf~ object seamlessly writes sound files in the background - why can't i load/record them into arrays just as seamlessly? (I use OSX and pd-0.36)
it's because a lot of graphics data has to be generated by PD and sent to the tcl/tk frontend. PD is not multi-threaded internally and deserves a far prettier and faster GUI than it has now. Watch out for news.
best greetings, Thomas
