Newbie MIDI Question

[Bahrain_Phill]

I have never used MIDI before. I own a cheap Casio Keyboard. I have been told I can use the MIDI ports on the back to a Sound Module and therefore not have to buy a new keyboard (I only desire higher quality sounds right now). Is this right? And if so, are they called sound modules? Because I am finding alot of items called drum modules...which is not what I am looking for. Sorry if I"m off in left field on this one. Thanks in advance.

What you have been told is correct. You could certainly use a drum module, which is a kind of sound module, if you wanted to create drum sounds using your keyboard as a controller. If you want a synthesizer module, Roland makes a nice one:

And here's one from Yamaha:
