You should try at some of the sounds I have at http://www.synthzone.com/midi/korg/01w/ as you are sure to find some great ones there. Often they are an improvement on the original factory sounds. They are in sysex format ( .syx ) and can be sent from your PC over midi to your Korg, presuming you have a midi interface for your PC. If you don't I recommend you get one because it not only allows you to send sounds but also to use PC midi sequencing software. And they aren't very expensive. http://www.zzounds.com/item--HOSUSM422 is under $30.

It doesn't matter whether you have a Mac or a PC. A USB MIDI interface would make a huge difference in how you can work with a MIDI keyboard. Inexpensive but so very useful. Even if you change keyboards a MIDI interface will work with all MIDI keyboards.
A Mac sysex librarian for sending and receiving sysex dumps is http://www.snoize.com/SysExLibrarian/ Then you could try out all those O1W patches in my archive.
