Akai EWI4000s as controller?

I have now an Akai wind controller and am having difficulty in setting LE8 to record the Akai's INTERNAL sound bank. It is attached to a USB E-MU1XMIDI 1X1 which is recognized by the Audio/MIDI set-up as using Port 1 in and out[I may not have this configure correctly-but that hopefuluy can be decided later. When I first plugged it all together I could access and hear any GB or sym-orch. instruments-but no response to the in- or decrease in volume I had been looking for. I realised that the Akai has it's own built in multi-synth,[?], and when played without the Mac, it's own instruments do have "Expression" possibilities breath control over amount of velocity AND volume, but only with headphones in the Akai, which also has MIDI in/out and a phono1/8 out. How do I configure LE8 so I can record the internal Akai instruments and hear, audition, them-I have already RTFMed-I looked at the LE8 Environment Window, thanks Apple for leaving the option available, and in clicks and ports there was the E-MU USB1X1 and so I cabled it through the same monitor as the USBKeyboard monitor to the sequencer and can see the increase numerically as I blow harder,no giggles please, but still haven't been able to set up a track that will allow me to hear through the Agregate Device,it has no midi instances as it's AUDIO,what I can see is going into the Enviroment monitor digitally. Your help is greatly appreciated and I Thank you in advance.
