Re: Buying E-drum set
On a TD-3 can only add 1 cymbal or pad to what it already comes with. On a TD-4 you can add 1 or 2. I'm not sure on the Yamaha's, but you could do a little research and find out. Just find out how many inputs there are, see how many pads it already comes with, and then you'll know how many extra inputs it has.
