Not really a very good direct comparison, Deane.

I must say, I wasn't tempted by the Tyros5 and would only be interested if I was looking for a 76 note Tyros.

The Audio Drums don't interest me at all...too many restrictions, and my Tyros4 has all the sounds and styles I use the most.

I also like the overall sound of the Tyros4 better...it's the best Tyros Yamaha has made, in my opinion.

Thanks,

Ian
