Hi.

I had a similar question when I bought my 3000. I emailed Yamaha Canada and this was what they said -

"Greetings from Yamaha Canada Music,

I was forwarded your email.

Only our TYROS and TYROS 2 (the models up from the PSR-3000) have actual after-touch which can be applied to their onboard panel voices. The PSR-3000 on it's own cannot produce after touch so the onboard panel voices and it's XG voices can't receive these messgaes.

As you have noticed, only via an external controller that produces after touch can the 3000 receive these messages.

As far as an XG chart (each PSR-3000) comes with a data list which can also be downloaded from this site http://www.yamaha.co.jp/manual/english/index.php

Type in PSR-3000 and save the data list.

Regards,

..."

I think the key part of this is "...so the onboard panel voices and it's XG voices can't receive these messgaes..."

Hope this helps,
Dan

P.S. I know messages is spelled wrong in the quote. It is a quote...
