Thanks for the test and feedback.

You probably asked for illegal parameters. The builtin audio stuff is
amazingly uncapable. Mine can't do 48kHz, for example. In addition, if
you change the sample rate when using an aggregate device, you will
randomly lose all output channels (confirmed by Apple). Note, in case
you are not aware, that Tiger ships without any duplex audio devices by
default - its up to the user to create an aggregate one. Almost as crazy
as ALSA :)

I am suprised by all the people who ask about this. I really wasn't
aware that so many people bother to configure the number of channels.
The default should be *all* the available physical channels. Is there a
problem with this?

Yes, this is a relatively small detail in the packaging right now. The
Generic MIDI "control surface" support is not included in the packaging.
Its very easy for me to correct this, and I will in a soon-to-appear

in what direction(s) ? changing what? zoom? position?

Much more likely to see AU first. There are various issues with
supporting VST, ironically because Steinberg have insisted on using an
older GUI API (old-Carbon-sort-of) rather than the new stuff. Its not
impossible, but AU will be easier.
