i understand your approach to minimize the use of externals. but i
have a few general questions about how pd works:
- dsp cycles: if i have a complex calculation that requires several pd
objects, will it take several dsp cycles (one for each object) or is
it calculated at once. eg, if i have an abstraction that does 100
calculations (one after another) when i send a bang, would it take
100 dsp cycles?
- how can you switch of the calculation of some generators /
subpatches / patches? (i would really need this in my patches)
- abstractions vs externals: i suppose externals would be faster (if
you want you could even write your external in the assembler
language of your machine), but require more ram (more code, maybe
larger classes)... is this correct?
thanks a lot...

The only people for me are the mad ones, the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn,
burn, like fabulous yellow roman candles exploding like spiders across
the stars and in the middle you see the blue centerlight pop and
everybody goes "Awww!"
