Hi all

I found that doing (officially unsupported) dynamic removal of objects causes a redraw of the dsp graph. Especially in big patches this can lead to audio drop outs. There seems to be a (linear?) relationship between the number of objects(connections?) in a patch and the time it takes for the dsp graph to be redrawn. At least I think the drop outs are related to the dsp graph redrawing because of the followig observation:

• [7(-[until]-[delete(-[s canvasname] requires 700ms (on my computer on the patch I'm working)

• [delete(-[s canvasname] requires 100ms

• [dsp 0(, [7(-[until]-[delete(-[s canvasname], [dsp 1( requires also only 100ms

It seems, that no time is used as long dsp is turned off, and only on turning it on again, the dsp graph is redrawn (cpu time is consumed).

Interestingly it requires very little time to create message-only objects, which makes me think that after dynamically creating an object the dsp graph is not redrawn. Why does deleting an object triggers it, even it was not triggered on creation time of that very same object?

Is there a way to 'manually' control the redrawing of the dsp graph and also to suppress it, when not necessary?
