Hi list!
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,
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.
Reading my mail I realized that I did not explain it all: the latency
problem starts when the dac~ is computing audio. As you can see in the
mixer, when I rise the master volume audio computation starts,
meanwhile if I set master volume to zero it ends. It is while computing
audio that the latency problem exists, so I guess the control side is
not the problem (am I in the right logic?) Nevertheless I have done
what I believe is an extensive control check in my patch, before and
after finding that deleting the mixer channels the problem ended. After
that I did another control check on the mixer part of the patch and
found no control feedback (my checks are visual, following line after
line, so, as human, I might be wrong, but I cannot find my error if I
did one).
