Re: AU Midi Output

We've some work to do here to implement this ourselves, but the API and "intention" is basically there - and this is the simplest part. You specify an AudioStreamBasicDescription with the 'midi' as the format type. The "stream" is a MIDI packet list, where the time stamps of that list are sample offsets for the current buffer (oh, and the ASBD's sample rate should be set so transformations to time can be done by the au when looking at these time stamps). The base classes don't have any support for this, but this is an exercise we plan on undertaking.

Thanks for the quick reply. This great news! I have already been
using the virtual midi workaround and it's ok, but certainly not ideal.
I'm glad to hear the platform will offer furst class support of this
feature in Panther. I'm sure many developers will see the potential
and jump to fill the need...

There's actually going to be an QuickTime update for OS X 10.2, too, that
will add these improvements to AU. So it won't just be limited to 10.3.

We will also need some support from the hosts.
I hope this will give an opportunity for Emagic to improve its MIDI routing capabilities, so effects will stay on effects slots, while being able to receive/send MIDI...
