Hi.
I've written a standalone MIDI sequencer application for Mac OS X
Leopard using Objective-C/Cocoa. It's highly parameterized and one of
the things I have been thinking about is how to automate those
parameters. It occurred to me that it would be very nice to be able to
integrate it more closely with my DAW, Logic, and use Logics own
automation facilities. But that means introducing it into Logic
somehow which means, I think, making it an AU.
I've done some brief scouting through the AU programming guide and
list archive and come up with two key questions I haven't been able to
answer:
* Is there any place in AU for pure-sequencers?
* Is it possible to write an AU using only Objective-C?
On a conceptual level, I am not sure how a sequencer would work in
this environment. In Logic there is Ultrabeat but that is both
sequencer and instrument together. Since my sequencer isn't an
instrument, if it takes the instrument slot on a track there would be
nothing for it to play. There are also effect slots but they seem to
follow the instrument in the signal path, it doesn't seem right to
think of the sequencer as "an effect". I'm left wondering if I am
barking up the wrong tree here.
Also all the examples seem to use C++ for the AU code. I don't want to
write any more C++ code so that would be a sticking point even if
there is a way around the conceptual difficulties. Can you write a
pure Objective-C AU?
Thanks,
Matt
