You cant compare these...
The tyros 5 offers much more, sounds like sa2 and ensembles, much better keybed..
the 900 offers a much better interface... and lots of smaller things..
In the end i personally would choose for the better keybed espescially a 76 key version and the superb sa2 and ensemble voices over the new interface
So Bachus T5 over Sx900?
Yes for the keybed and the SA2 voices...
But then, i don’t have to choose between them...
As i am in a perfect spot with my Genos..
