Hi Ky,

How long was the demo for? were there many people watching it?

There is no way its worth trading your T4 plus handing over 4.5k cash to get a T5.. IMHO! you need to ask yourself - what are you really lacking from the T4? is it drums? if so - the T5 is not going to be THAT much better... Ive heard alot of demos and any of the styles that are NOT audio styles on the T5 sound ALMOST the same as the T4...

If you are bored of the T4 or want some new sounds and styles - keep the T4 and purchase some of the premium expansion packs...

Yamaha use the audio styles to showcase the product really well. it makes the demonstrations sound unbelievable!... but only 40 styles are audio!!! They really know how to market something and close the deal with the customer but day to day use there is a good chance you will very soon get bored of them!

My PSR S950 has audio styles and they are the exact same quality of the T5.. just different styles... the fact that u can NOT edit or remix any of the audio drums is very frustrating... when you first get the keyboard you cant stop listening to them because they sound superb overall... but is your keyboard or song database actually needing the audio styles provided?? Just think of what styles u are using for most of your music or favorite songs u like playing day to day on the current T4 and ask yourself if having the extra 40 audio styles will change anything?? If yes - then great. but if not.. then they will be nothing but a gimmick to you...

Good Luck mate. let me know what you end up doing?
If you get a T5 ide be keen to come back for another rd trip and have a jam
