One thing I did find strange (I think this is likely a bug in Cakewalk) is that the plugin remains in the ‘activated’ state when calling activateBus. When I instantiate the plugin on a track, and then direct another track’s output to the plugin’s sidechain input, I see that prepareToPlay is not called again (as you reported) - however, the call to activateBus on the VST3 wrapper ends up calling the virtual function processorLayoutsChanged on the AudioProcessor, alerting it that its bus layout has changed. My testing plugin is a modified version of the AudioPluginExample demo project with an optional sidechain input.

I’m testing with 2021.12 build 102 on Windows 11. If the VST component->process call has a zero buffer size JUCE should not call processBlock to solve this issue. However, JUCE makes an unnecessary call to processBlock which can cause some plugins to misbehave.

In this call the plugin is supposed to only update parameters and no processing is done. This call can be made even BEFORE the plugin has been activated. VST3 has a documented mode where a “null” process call can be made with a zero buffer size to pass parameters state to the plugin. However that would mean that there will be multiple calls to setupProcessing.Īlso, I found another issue with JUCE’s VST3 implementation: Perhaps activateBus could also call that function. Since activateBus can be called after setupProcessing the plugin can’t rely on prepareToPlay to get the number of active channels. However, it is not called in response to component->activateBus (JuceVST3Component::activateBus) PrepareToPlay is called in response to a few scenarios like this: I’ll send you an email with further details. So, there is still an issue, but not exactly the one I was reporting. This=00000000143DCDA0 processBlock : getTotalNumOutputChannels=5 buffer: 5 This=00000000143DCDA0 prepareToPlay: getNumOutputChannels: 5, Real-time:1 getBusCount=4īus0=Output, enabled=1 getNumberOfChannels=2īus1=Aux1, enabled=1 getNumberOfChannels=1īus2=Aux2, enabled=1 getNumberOfChannels=1īus3=Aux3, enabled=1 getNumberOfChannels=1 This=00000000143DCDA0 processBlock : getTotalNumOutputChannels=5 This=00000000143DCDA0, numChannelsChanged: 5 isThisTheMessageThread=1 This=00000000143DCDA0, numChannelsChanged: 4 isThisTheMessageThread=1 This=00000000143DCDA0, numChannelsChanged: 3 isThisTheMessageThread=1 This=00000000143DCDA0 processBlock : getTotalNumOutputChannels=2 Here is a log (from the JUCE point of view) of the current behaviour, you can see that there are two calls to processBlock() that have five channels before the actual call to prepareToPlay: this=00000000143DCDA0 prepareToPlay: getNumOutputChannels: 2, Real-time:1 getBusCount=4 bus0=Output, enabled=1 getNumberOfChannels=2īus1=Aux1, enabled=0 getNumberOfChannels=0īus2=Aux2, enabled=0 getNumberOfChannels=0īus3=Aux3, enabled=0 getNumberOfChannels=0 I was using version 2021.11 when I wrote my post – I have now updated to 2021.12 and the behaviour seems a bit different, but I don’t know if it is the version change, or if it just that the issue is a bit random.
