Subject[Csnd] qutecsound realtime performance
Hi Andrés -

I have some problems with the realtime performance of qutecsound. I'm  
on a MacBook, and even running the simple example below (which comes  
with qutecsound) with ksmps=1 instead of ksmps=128 gives dropouts. Is  
this the same for you (or anyone else using qutecound), or can I  
adjust anything?

-odac -iadc
; -o test.wav -W



sr = 44100
ksmps = 128
nchnls = 2

instr 1
kfreq line 100, p3, 1000
aout oscil 10000, kfreq, 1
outs aout, aout
endin

instr 2

endin



f 1 0 1024 10 1
i 1 0 5

Yes, it works without any problems from the command line or from the  
jEdit console.
The messages about the cpu usage are:
Running from the Terminal: real: 5.437s, CPU: 0.670s
Running from qutecsound: real: 9.721s, CPU: 9.770s

Is this working on your machine? What can be the reason for such a  
cpu usage?

I'm attaching the messages, if you like to compare them.
