I'm looking at buying an Audya 5 or 76 key. Difficult since stores don't carry Ketron or even the Tyros 4 in my state.
I'm having to go off of reviews and the internet which is lacking in info.

My main use is backing while I play guitar.

1. Can you hook an external midi keyboard (i.e.) 88 key, to the Audya 5? You should be able to, but I know the devil is in the details.

2. Still tryin to decide on the 66 key or 76 key. Comments?
The 76 key is $800US more than the 66, which I don't understand.


3. Also I'm still trying to decide Tyros 4 vs Audya 5? Thoughts?

Thanks
Kevin
