Programming an Audio Unit that hosts another Audio Unit?

2012-08-07T20:42:33Z

I need help programming a Audio Unit that wraps a 3rd party audio unit.

I am trying to develop an Audio Unit instrument using Xcode. I want my AU to load an instance of a 3rd party Audio Unit called Massive by Native Instruments. I want all MIDI notes passed to my AU to go into the Massive AU and the output of that is the output of my AU.

I just want my AU to programmatically control some variables of the 3rd party one and pass through all sound/MIDI to it too.

I can't seem to find any examples of how to do this. Also, I am a newbie with Core Audio and the documentation is very hard to understand. I don't really know what I'm doing with Core Audio...

Can someone please tell me how to do this?

Thanks.

Spend some more time reading the documentation. Discuss in the Apple Developer forums.

Forget your project and use something that's already been made: http://www.plogue.com/products/bidule/

I did this a couple of years ago and published the results at last years International Computer Music Conference (http://eprints.bournemouth.ac.uk/18249/1/ICMC2011%2DPaper_Final_Camera_Ready_ver2.pdf). It is fairly tricky to do and I could not find any example code. I found the hardest aspect was managing the UI.

Besides AU, there's a plugin named Patcher of FL Studio for doing this to VST's.
