VST3 (midi) and JUCE

JUCE Arp example is pretty simple and straightforward and MIDI only - but it does not work on VST3

I don’t know why they don’t fix that, but you just need to add an audio input and then it works:

    Arpeggiator()
    
    : AudioProcessor (BusesProperties().withInput("Input", AudioChannelSet::mono(), true)) // seem to need for sampleRate
    //    : AudioProcessor(BusesProperties()) // add no audio buses at all - Original, doesn't work
    
    {
        addParameter (speed = new AudioParameterFloat ("speed", "Arpeggiator Speed", 0.0, 1.0, 0.5));
    }

processBlock() will not be called with a valid number of samples unless there is an audio input.
