One great advantage of maxmsp is gen, which gives you sample-level patching 
with the possibility of a one-sample delay.


you can use [block~ 1 1 1] in a pd subpatch.

    David,

    One thing I attempted and couldn't find a solution for was the following, 
mostly owing to the limitation of interfacing with a 64 sample block size.

    I wanted to have a directory of hundreds of audio recordings. Each one 
would be a single wavelength from an interesting sound, like a bass clarinet, 
marimba, harpsichord, tambourine, etc. Each would begin and end at a zero 
crossing so you could chain them together to make complex timbres. They could 
be chained in sequence, randomized, or loaded in meta-data-matched chunks. I 
ran into a problem figuring out how to trigger the next sound based on the 
ending of the last sound in a sample accurate way. Sound file loading or even 
buffer playback triggering waits until the start of the next block size before 
it updates. If you have a waveform that lasts 205 samples (64+64+64+13), you 
have a gap of 51 silent samples before the next waveform would start. Not only 
do you not get the continuous sound you want, this winds up creating a periodic 
pattern with a frequency of 689 Hz (44100/64).

    David, I like your idea "what (if anything) someone tried to do in Pd, but 
couldn't given its limitations". I think this could be a wonderful challenge if we 
could have a monthly thread like this where the best minds among us come up with 
solutions to some of the hardest conceptual challenges in Pd.

    I'm still struggling with loading dozens of files, audio dropouts, and other similar 
problems. Someone else expressed frustration about Pd's single-threaded status. I too 
have feared upgrading my computer based on the limitations of current multicore 
processors (although realistically I think we can all look at the "turbo-boost" 
level or whatever Intel calls it to determine where our processor might run with a 
demanding patch. I understand the fact that you can't run your audio process on multiple 
cores, because it is a linear process. It would be great if the GUI could run on a second 
core, a process that loads audio into memory could run on third core, while GEM could 
automatically run on a fourth core. I don't have any concept of how feasible that would 
be, though. Does the GUI in pd-l2orc run on a separate core?

        One thing I'd be interested in knowing about is what (if anything)
        someone tried to do in Pd, but couldn't given its limitations (apart
        from look/feel/convenience issues).
