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
<
--------------------------------------------------
VERIFYING DEFAULT SCOPE FORMATS:
Input Scope Bus Configuration:
Default Bus Count:2
Default Format: AudioStreamBasicDescription: 2 ch, 44100 Hz,
'lpcm' (0x0000002B) 32-bit big-endian float, deinterleaved
Output Scope Bus Configuration:
Default Bus Count:1
Default Format: AudioStreamBasicDescription: 2 ch, 44100 Hz,
'lpcm' (0x0000002B) 32-bit big-endian float, deinterleaved
* * PASS

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
