I was wondering how possible it is to connect an electronic drum kit (this one:http://www.roland.com/products/en/TD-6/index.html) to Reason Redrum (via midi)?

Having a quick look at the Redrum sequencer and there doesn't seem to be enough 'channels' to accomodate the whole kit. .?

(i'm at total Reason noob. .)

Thanks in advance
