hello,
sorry if I missunderstood, but : what's the differences with vasp?
cvs\externals\grill\vasp\readme.txt :
"VASP is a package for PD or MaxMSP consisting of a number of externals extending these systems with functions for non-realtime array-based audio data processing. VASP is capable of working in the background, therefore not influencing eventual dsp signal processing."

hi all,
i'm currently investigating the possibilities of making pd's array operations threadsafe to avoid audio dropouts...
apart from objects that fill arrays in realtime, there are two possibilities of working on arrays:
- soundfiler
- messages to arrays
one of pd's language basics is that messages should be processed at once. the problem of this is, that if the array operation takes too long, it results an audio dropout.
my proposal: we could implement two different behaviours for messages to arrays and the soundfiler:
- the soundfiler works in a low priority thread on the array, syncronizing with the patch by a message to the outlet of the soundfiler when done...
- messages to arrays should be processed at once and may result audio dropouts
this way, we won't have to break with pd's message handling ...
to achieve this, we will definitely have to add a thread lock for arrays. i'm willing to implement that, but i'd like to hear, what the other developers think about that...
cheers...
