Hallo, Matt Barber hat gesagt: // Matt Barber wrote:

Depending on what your patch does, you can often put much of the "engine" of your patch in subpatches, and then make a "control surface" with sends and receives.

Note that GUI objects even in subpatches can lead to more CPU use. At least I once managed to make a patch perform much better by removing a lot of [bng] objects hidden in abstractions or subpatches. The example is somehwere in the list archive, maybe I can find it again.

I don't know the code well enough, but I could imagine the following:

What would happen to the CPU usage if you had replaced the [bng] objects with [bang] objects? Or is the architecture such that an object only computes if its outlet is connected to something? If that's the case, I could imagine that another difference between [bang] and [bng] might be that the [bng] always has to compute the bang whether or not its outlet is connected -- maybe it would have more to do with this than just its being graphical. But really I don't know, just speculating late at night.

Thanks,

Matt
