Hi List, Hi Larry

I havent been using PD for a while.

But i have a little project which i like to explore

I found i nice "scheme" script in the context of the linux-sound-editor "snd", that synthesizes plenty of birds, animals and insects.

So i was wondering if it possible to get this running inside of PD, so i can be played in realtime...

How difficult is it to compile "SIOD" on OS X ?

i dont know much about "scheme" and various dialects - so i post a little snippet of the code, to find out, if that would work.
