Buffer Size is Zero in processBlock() for Midi Effect in

I have created a MIDI effect from Projuicer. I am debugging it in Xcode, using the JUCE AudioPluginHost. I have taken processBlock() from the Arpeggiator example. But buffer.getNumSamples() returns zero. Should this work, or is there a new method for calculating timing in a MIDI plugin? // the audio buffer in a midi effect will have zero channels! jassert (buffer.getNumChannels() == 0); // however we use the buffer to get timing information auto numSamples = buffer.getNumSamples(); I do get …
