AUv3 Question


  • Subject: AUv3 Question
  • From: Brad Howes via Coreaudio-api <email@hidden>

Hi,

I have an AUv3 app extension that relies on an AVAudioUnitSampler to do the
work. In my application, I can trigger a sound event when the user changes a
preset/patch, but I am unable to get the same result from the AUv3 extension. I
tried three ways:

Commanding note on/off via the AVAudioUnitMIDIInstrument startNote and stopNote
methods (this works just fine in the app version)
Commanding note on/off via the AVAudioUnitMIDIInstrument sendMIDIEvent
Posting MIDI events to the scheduleMIDIEventBlock of the AUAudioUnit

When I play a note on the keyboard of the AU host (AUM or Audiobus 3) I see
MIDI events arrive on the internalRenderBlock, but I do not see anything there
due to #2 or #3. Should I?

So my big question: how can I command the AVAudioUnitSampler to play a note
when it is being used inside a AUv3 AUAudioUnit, just like it does when it is
running in an app?

Thanks in advance!

Regards,

Brad
