Thanks guys. Don't really know much about VST. I'm really looking for a keyboard to mess around on at home but, at some point in the future, to compose on. Nothing too complicated as, apart from the old PSR-SQ16, I am quite new to this.

I've been looking at the Korg Micro X. If I bought one along with a PSR-S900, would I be able to play sounds from both instruments using the PSR-S900 keyboard? Would I be able to incorporate sounds from the Korg into music that has been sequenced using the PSR-S900's onboard sequencer? Are there any good alternatives to the Korg?

Sorry for my lack of knowledge but, as I said, I am a newbie.
