Numa Organ and Digital Performer

I just got a Studiologic Numa Organ, and I am very pleased with it.

My Sequencer is Digital Performer 8,1 on Snow Leopard

My Audio to Midi Setup sees the Numa ONLY if I connect it directly through the USB port to The Mac

Audio to Midi Setup will also see my MOTU 128 Express interface also when connected through the USB port however I am unable to connect the Keyboard to the Interface as everything is grayout

If I connect the Numa directly to the USB interface it doesn't appear in Audio to Midi Setup and Digital Performer doesnt Remap the Instruments

The Numa is set as "Local on / MIDI on"

While rcording I can see the various notes in the DP track, nowever when I play back the Numa doesn't make any sounds

Any suggetions?

PS

The MOTU USSSB interface is upgraded to the lateset version
