Does a jit.gl.bfg run if not connected to an aoutput ?

Hello,

For a project I need to use some [jit.gl.bfg] and [jit.gl.pix] in different context along a time line. I could change the [jit.gl.bfg] and [jit.gl.pix] parameters along the playback of the time line (a sound file) or create different "pipes" for each portion od the sound playback and then connect the different pipes individually to the [jit.gl.videoplane] on the different points of the playback/timeline. The last solution is the more convenient but it implies to have several [jit.gl.bfg] and [jit.gl.pix] in parallel with only one rendered to the world playback window.

My question is : would all those different parallel [jit.gl.bfg] and [jit.gl.pix] render and use computer ressources or is it only the one connected to the [jit.gl.videoplane] that will effectively render meaning only one that renders and use computer ressources?

Or maybe, there is a better way to do it, of course !

I join a very shematic example of the idea to make it more clear (not working of course)

Thanks ?
