MIDI Effects implement the MusicDeviceMIDIEvent and RawData methods
from MusicDevice.h - the type is different (which tells the host you
implements MIDI)

Quick followup question:
Is there any way I can get MIDI note information through the
AudioUnits API, or do I have to add my own MIDI code using CoreMIDI?
Any problems or pitfalls I should be aware of?
Thanks again!

Hi tahome,
the pointer thing is something that I found out while testing
around the
same problem with HasInput() (that it always returned TRUE).
It still looks strange to me, but in my case it worked, so I used
it. Just a
workaround.
This way did not work with AudioBufferLists in my AU.
I use GetChannelData() instead of the GetBufferList().

Bill and Bernd, thank you! It looks indeed like a bug in Logic 8 to
me.
Bernd, I tried something similar to what you are suggesting, like
comparing the pointer to the audio data in the ABLs that I get from
the side chain and the main input (ie sideChainAbl->mBuffer[0].mData
!= inputAbl->mBuffer[0].mData). They appear to be different so
there's
no telling if the sidechain is connected or not. I did not use
GetChannelData(), however, I might give this a try, even though I'm
not sure what difference it would make (it should point to the same
data, right?).
I am curious - how do you know the two pointers have to be the same
in
Logic if the sidechain is not connected? Ie. what is the logic behind
this - is this just something you discovered empirically or is this
documented somewhere? Is it guaranteed to work? I mean, Logic could
as
well use some pre-set buffer containing silence for an unconnected
sidechain, couldn't it?
Thanks again,
