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
Hi...¿Kernel? ... probablemente debas compilar un kernel de baja latencia...tiene poca ram y un procesador pequeño, igual debería funcionar...
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...
Try mixer~ objetct
Best regards
José

maybe because xfce is lighter and cooler than gnome?
apart from the different desktop environment, there is no difference between xubuntu and ubuntu (afaik)

Pd is designed to have a constant latency.
so Pd's (and the system's) latency will never when moving a slider (well, unless you control a delay with the slider or do some other explicit latency fuddling, but that's a different story)
or maybe you are referring to GUI latency? e.g the slider starts to visually respond very slowly (it seems like in CM-talk, "latency" mostly refers to audio latency). without having looked at your patch, a good chance is that you have created some control feedback.

Ubuntu, xubuntu, kubuntu are all the same distro with just a different flavor for the window manager system (X).
