Dear List,
i have made a simple real time looper in csound. I have a trivial gui in
python tkinter, or an external midi controller. The purpose is only take a
real time audio input and then looping this and then apply some simple fx
like reverb or ...

This is my question:

in the csd i can use only one instrument for all the audio path, but i would
prefer to separate every work into a different instrument. Now i would like
to know about efficiency of different way to do that, i.e. globals audio
variables, zak space, last signal flow graph of Mr. Gogins, or ?

Are these more or less expensive in computation or are all the same?

Thanks,

ciao,
fran.
 

You can use audio channels as well (chn* opcodes).

Can i use chn opcode for internal communications (from instr to instr, into 
a single csd)? Are they not only for external (via API)?

Thanks,

ciao,
fran.

I think globals or zak would be the most efficient, but probably the
signal flow graph would be easier to set up and should be efficient
enough. I have not done any comparative tests, though.

I'm quite fond of the Mixer opcodes myself. MixerReceive, MixerSend
etc...  It's a nice model, and relatively easy to do on-the-fly signal
routing with them.
