The problem was solved:
i am using an M Audio Key station 88 , it requires power which it can get form the USB on the computer. When using the USB to the computer to transmit the midi data it doesn't recognize the signal and would not play. When using external 9V power on the keyboard and running a MIDI to USB cable the stand alone Hammond B3 X works just fine. Hope this helps someone who may be having the same problem. Macbook Pro 2012. No latency as I have switched out the hard drive with a solid state. And Im only running 2x4 ram . zero latency.
