micro tuner on external midi HW ?

Hi.
how can i have micro tuner midi insert to work on external HW midi device ?
it only works for steinberg VSTi,it wont work on kontakt for example.
does the micro tuner sent any midi over midi/usb cable ?
maybe there is a filter somewhere that prevents sending its pitch data ?
tried it with Korg PA4 arranger and it wont work :bulb:
