When starting PD by double-clicking, it sets its working
directory to  the root  (/  or 'Macintosh HD'). Put the
csapi_demo.csd
there and csoundapi~ will find it. (or else give the
full-path to it,
but PD has a limit on the size of strings, so if the path is
too long,
it will not work).

What is happening in this situation is simply that any opcode libraries 
not found in the static libcsound.a (the opcodes listed if OPCODEDIR is 
not set) are not being loaded by Pd since no environment variable is 
set. Could it be possible to use the .profile as a mechanism to set 
environment variables ?

Anyway, you can prove that it's simply an issue of opcode libraries 
being loaded by running a simple orchestra that has only an oscil 
generated sine wave - the csapi_demo.csd has a flanger opcode (and one 
other I think) which is not a part of the static libcsound.a and 
subsequently requires the external libraries be loaded.

Peiman, see if .csd this works in your Pd:
