Hi,
I assume, by the lack of response to my original message, that this is
new territory...
Has anyone successfully implemented an AU effect with a side chain
(stereo in + side chain)? Is this possible? If so, what must be done to
have the side-chain recognized by a host? What hosts even support side
chains in AU effects? Are there any?
Thanks,
Brandon

Hi,
I am trying to get a side-chain working in an AU effect. I read some
old posts on the subject, but they dont seem to help. It looks like
all you need to do is create a second input bus which is done in the
AU's ctor (the AU is derived from AUEffectBase):
TheAU(...)
: AUEffectBase(...)
{
CreateElements();
// need two input elements for the sidechain
Inputs().SetNumberOfElements(2);
...
}
AUValidator output

The AUValidator confirms that the AU has 2 input busses, but Logic
does not show the side-chain menu in the GUI. Is there something else
that needs to be done here to get the extra bus recognized? What hosts
support side-chains in effect plugins?
Thanks,
Brandon
