Hi (first post here),

I am currently working on what must be probably my third try in porting the Delay Lama to an AU-instrument. In the VST version we got a list of midi (or VST) events from the host, used our own written code to place these in the comming process buffer and handled them sample-accurate with our smoother.
In order to build something similair in AU, I come accros some questions. Most important is: should I overwrite HandleMIDIPacketList(*) or HandleMidiEvent(*) functions from AUMIDIBase in order to be able to process several MidiEvents, coming in the same buffer. Or can I just use the HandleNoteOn(*) and other midi functions with their inStartFrame value. And how does this work when there are more then one midiEvents of the same type in one Rendering buffer (this especialy was the case with our use of the pitch-controller to have 14 bit control over the vowel position in our vst version)?? And are there any hosts yet working with the StartNote(*)/StopNote(*) calls?


I'm currently reading how to work with the XCode debugger, so I can get into more of these kinds of things via the back-door and have a little peak myself, but any hints on using the debugger (basically just for stepping through code as it is running) are welcome.

But handling more then one event of the same type within one rendering frame is the biggest ? I have at the moment.

Any help appreciated.


Hi,

Just inherit from MusicDeviceBase and redefine HandleMidiEvent, it will be just like processEvents when events are VstMidiEvent except that data has been already split in AU.


Hope this helps
