Don you know you want it for xmas... go for it life is too short

Just finished listening to the entire comparison. Both keyboards sound fantastic - no doubt about it! My take on them:

Pianos - both about the same for the Grand Pianos, maybe a bit more depth to the Yamaha, though.

Guitars - Definitely Yamaha gets the edge here.

Organs - Korg has some really neat effects.

Brass - Yamaha gets the nod here - great brass.

Stings - About equal, IMO.

Drums - Yamaha by a mile. Much hotter, far more realistic, crisper, full sounding.

Don, get the T5!

The Korg PA4X-76 weights more than the Yamaha Tyros 5-76.

Gary ... as I have said before, the beauty of sound is in the EAR of the beholder ... and, ol' buddy, if you are going to critique the sound of KBs, maybe you should stop telling us you are deaf as a post !!!

Here are the dimensions

T5-76 4X-76 T5-61 4X-61
33.07 35.94 30.86 30.65 WEIGHT IN POUNDS
53.43 46.97 44.88 38.58 LENGTH IN INCHES
5.6 5.0 5.6 5.0 THICKNESS IN INCHES
17.7 14.4 17.7 14.4 DEPTH IN INCHES

The PA 4X is about the same size as the PSR S970....nice.

Since neither has built in speakers...maybe the difference in sound has something to do with the PA/sound system being used for each keyboard??

to say Gary I really Love mine T5 /76 it get better as I dig in the Electric Guitars are just the best period

it a great Keyboard the PA4X sounds great too it a great time to be a Keyboard player Gary

I am also impressed with the 970 as well I still have my T4 61 and love that too.

Gary, if somebody GAVE me a Tyros 5, I would just sell it and get something easier to move around. I will only be getting a 61-note version of anything I might get.
The Korg PA4x is outstanding size and weight for a top of the line arranger.
They really didn't demo many of the sounds I'm interested in. I know Yamaha has an outstanding Pedal Steel and Korg doesn't. Maybe the 4X will.
I'm interested in electric guitars, saxes, piano, organs, fiddle, harmonica. . . more or less in that order. Both brands have really good acoustic guitars. Piano on either is fine, as is organ, strings and harmonica. Electric guitar still go to Yamaha, but I have heard snippits of some really good ones in the 4x.
It's fun to speculate.
At this point the operating features, ease of setup and transportation are more important to me than sounds, and Korg is WAY better for my needs. Yours may differ!

Here are some of the new PA4x guitar sounds. Outstanding Strat and Les Paul sounds, completely editable amp sims, etc. Looks as if they are finally getting it!
