Make sure you are transmitting on the MIDI channels that the D-10 is set to receive on. From memory I recall in multitimbral mode the D-10 can receive on 9 MIDI channels eg. 2-9 for instruments and channel 10 for drums. If you are in performance mode then you are probably restricted to one MIDI channel total. Just check what MIDI channel you are using on the D-10 anyway.
