Hi Chris,
That's interesting and would certainly provide a solution. A *big*
problem that I forgot to mention is that the Matrix mixer (and the
improved Stereo mixer) is not available for Jaguar and I'm not sure I
want to restrict a new product to Panther customers only.
Thanks,
Robert.

Robert,
All of these features are very doable by connecting several matrix
mixers
together in the right way, along with the built-in lo-hi shelf and
parametric
EQ AudioUnits. Also, in Panther, the stereo mixer will mix
stereo sources (but not in the WWDC seed - sorry ;-)
Although, the matrix mixer may not present the controls in the way
you're
used to seeing them, it's fairly straightforward to write a "wrapper"
AudioUnit which internally uses matrix mixers, etc., publishing the
parameters and busses in exactly the way you describe...

As I've written before :-) I'm not happy with my mixing options as an
AU host developer. The Stereo mixer is too basic and the new Matrix
mixer (which I guess we can discuss now that Bill has mentioned it
:-)) is too "matrix" for lack of better description.
What I'm looking for is a mixer that is somewhat akin to real-world
mixers. I want:
Stereo/mono inputs
per input:
input gain fader
input balance/pan (balance for stereo, pan for mono)
send levels
pre/post fader switches for the sends (not essential but nice to
have)
Some basic EQ (lo/mid/hi) would also be nice but not essential
multiple stereo effect send busses (say 4)
Effect Return busses if it's technically feasible (see below)
Stereo master out.
The way I see it working is that this mixer could be coupled with the
stereo mixer to provide a full featured mixing environment. Seems
easier than trying to embed the send effect loop within the mixer -
but if I'm wrong I'm happy to hear it :-)
As I've demonstrated here many times I'm not talented enough to build
this myself or even have much idea about how to get started. So I'm
interested in working on a SourceForge type project with a BSD-type
license (because I want to build commercial apps with it) with a few
others - I'd probably be able to fill in some of the blanks :-). It
wouldn't need a GUI I think because hosts would happily provide their
own (especially if it is often coupled with the Stereo mixer).
Is anyone interested in helping out?
Thanks,
Robert.
