Hi, I'm not too familiar with Pd, but I have some experience with embedded programming and I would like to see if I can quickly simulate applications in Pd rather than go to the trouble of programming them on a chip...

when programming fast, timing crucial patches, what are the limitations of pd? How fast can I compute a real time audio stream? Are there any ways of optimising patches etc.?

Can you program your own objects (preferably in c)? Presumably an object in c will run quicker than a patch made out of separate objects to do the same thing?

hints, tips, links to articles MUCH APPRECIATED

@vixo I haven't really had time to work with this yet, but you may want to look at this :

Hi vixo,

Concerning creating your own externals, I suggest you take a look at this pdf here: http://pdstatic.iem.at/externals-HOWTO/pd-externals-HOWTO.pdf

Presumably an object in c will run quicker than a patch made out of separate objects to do the same thing?

I believe this will depend on the complexity of the task, as well as the type of objects you use. Some objects are notorious for using more CPU than others, but depending on what you want to do a Pd only solution could work very well.

Cheers!
