There is no published interface to this Send "effect" - it's not a real
DMO, just an internal DSound construct.
To work around this, you could create a simple "Volume" DMO that sits
right before the Send, and change the volume that way.
I'm not sure why the "shared" buffer solution isn't working. Are you
explicitly setting the "Share buffer..." flag, and setting the GUIDs of
the buffers to be the same? This is actually more efficient than using
a Send effect, so I'd like to know why it's not working.

Subject: [directmusic] audiopath config Send "effect" c++ interface?
(DX8.1)
I am having tons of fun creating custom audiopaths with the DMP
audiopath=20
designer.
HOWEVER
There doesn't seem to be a way to get an interface to the Send "effect"
in=20
code (c++). I can query interfaces for the DMO effects and change their
values in real-time at run-time (great fun!), but no interface seems to
be=20
defined for Send. I'd _love_ to be able to programatically alter Send=20
level. Does anybody know if this is possible, and how? It seems like it
can=20
only be authored and is not accessible at run-time.
Example application: a single mix-in distortion buffer is shared between
n=20
sink-in buffers. Each sink-in buffer dynamically controls its send to
the=20
shared distortion buffer in response to game parameters. (Dry is
constant,=20
wet varies with the action.)
Possible (Send free) implementation: create a shared "reverb" or
"chorus"=20
bus sink-in buffer with distortion and use cc to control its level.
Unacceptable limitations: 1) only the dry synth signal is available to
the=20
sink-in buffer bus. (Whereas the Send "effect" could be at the end of
an=20
effect chain and send a wet signal to a mix-in buffer.) 2) "reverb" or=20
"chorus" bus sink-in buffers don't seem to work properly as shared
buffers
MS guys? Is Send a DMO interface? If so, why isn't the interface exposed
in=20
the SDK? (Please tell me this is available in DX9!)
Thanks,
Andrew
