G70 - V -Va76 & G1000 Sound

Has anybody come accross this before?
Have paid for a G70 and have used Va76 and G1000 Before with backing tracks.

But the sound files are well.....
Are Dead sound compered to the others and quality all over the shop have tried Ver 1 and Ver 2... And have tried diff Settings?

Also tried another g70

Is the G7o a lost cause?
