Unity Wrapper Midi Issue (SOUL > Unity via JUCE)

So I’m trying to go from SOUL to UNITY via JUCE. The midKeyboard responds to GUI presses. The wrapper appears to wrap the process functions correctly and the component has a midiKeyboard listener on. Does anyone know why the JUCE UNITY wrapper might not be getting midi through properly? And the unityMouseDown wrapper passes on any mouse presses so I don’t see why midi may not be getting through.

It’s the same for both SOUL909 and the JUCE sampler examples. Do I need to handle the mouse clicks separately in the c# script or something?
