Hi...¿Kernel? ... probablemente debas compilar un kernel de baja
latencia...tiene poca ram y un procesador pequeño, igual debería
funcionar...
I am not really a power user, but I haven' t had latency problems
before, so maybe this is not the central problem (but I understand that
you may be right and I could improve performance with a kernel change,
only that, if I can solve this latency problem in an easyer
inside-puredata way, I will leave it for a later macro-system optimizing
stage)
Maybe you could compile a low latency kernel... your processor is
slow, but must go on... check the latency...
Why you use Xubuntu??? try Ubuntu... i worked with open cv, pidip and
other in a little cpu...
As Iohannes lets think, I use xfce for its lightness and minimalistic
user interface. I hope there is not a problem in the interaction between
puredata and xubuntu's xfce environment.
Try mixer~ objetct
Thank you, I will substitute the before-master audio mixing with this
object and see if the problem solves, at least as an alternative try.
Gracias, y mejores deseos
Fernando
Best regards
José

Hi list!
I am trying to design a mixer with integrated effects on each
channel. The effects part is not started yet, and I have a
particular problem with the mixer itself:
If I move any slider in my controller to raise the volume of any
channel, it works perfectly well, but if I move the master level
the latency starts to get crazy and the resulting values come
really slowly, and then if I move any other volume slider (of the
mixing channels of any other values in the master patch, being
instrument values or sequencer values) the latency still is really
big.
I tryed deleting all the mixing channels and moving the master
level slider and there is no problem then, so I guess the problem
is in the mixing channels.
I also tryed deleting all the instruments and it didn't solve the
problem neither.
As you see the mixing channels are all abstractions (canalmezcla
n), and the master itself is one of these abstractions.
I am running puredata Extended 0.41.4 in Xubuntu in an HP Pavilion
dv 1680us 1.83 Ghz + 1 Gb ram. I believe the hardware is not the
problem, and the rest of the patch works fine.
Thanks for any tip!
Fernando
