Using the new 'Internal MIDI In' Feature in Logic?

Hi, out of interest has anyone successfully used the new “Internal MIDI In” parameter in Logic to record the chords/arps that Scaler generates? I know Scaler2 has the MIDI Capture, but I’m just curious. I had a play around with another MIDI plugin the other day and was capturing the output, but I can’t seem to do it with Scaler2.
