N-track ios filtering out low midi notes


I am sending midi data from Gestrument ro to N-track on ios and N-track seems to always filter out midi notes below c0 or above c8( i cant get it to receive c-1 or c9 for example) there is nothing else in my chain that would cause this issue

How can I fix this so that n-track will receive the full spectrum of midi notes 0-127?

Thank you!!
