Is there a way to force calls to processReplacing?

[Robert]

It seems that for the AU version of my plugin there are no calls to
processReplacing when there is no audio passing though the plugin. Is
there any way to force my plugin to continue calling this function?
Or is there some other method that is periodically called when the
plugin is inactive?

Try setBypass. I don't have that much experience with it, but the
theory is that your processing method will get called also when the
effect is bypassed (and yes, you are then responsible for letting the
input audio pass through). Notice that if you have reported a latency
you must keep that latency also in bypassed mode. Symbiosis supports
all this, but again, I'm not sure how well tested it is.

Awesome.  I will check this out.
