on purpose i minimized the window as soon as it played and I am going to copy and paste below exactly what I wrote whilst they played:

First of all, SMF's dont do it for me, but this is a pretty good one, a little slow though.

The first keyboard is very good and I was expecting it too sound lifeless due to the SMF but it was suprisingly life like. I am thinking...please dont let this be the Tyros!! Nice rich bass, lovely brass section samples and superb baritone. Not a nice guide voice though. Very good balance on the DSP giving it a live sound.

The second, also very good but why is someone winding a clock up through most of the track???? Putting that very off putting clock winder aside it sounded fine and the latin Piano is nice, poor lead voice though and the baritone is farting. Nice tuned Tomms and the DSP is good, but it sounds like its recorded in an emptry ballroom.

The third keyboard. What is this??? I only got half way through ..it is totally uninspiring.

So...

Then I checked back at the video and I was very suprised by the results. I was very dissapointed by the Korg as I have always liked their gear and expected it to be better than the Tyros. The big blow to me was that as an SMF player the Tyros sounded almost as good as the Audya except for the stupid clock which seems to have no bearing on the rest of the percussion section!

I also listened to the Roland afterward. But for me (and i realise everyone hears things differently) its so, so cold, there is no heart or soul in it. Its funny because there is nothing wrong with the sound...its just there is something missing..like I said it lacks soul.

Here is your benchmark to all three:

listen to that and then go back and listen to the SMF and see which sounds most like it.
