Reply to Korg KP3 questions

Hey all, looking for owners of the KP3 to answer some questions for me.
-How many effects can you run simultaneously with the hold function? Couldn't find this anywhere.
-Also, could I route my guitar to the KP to my interface and have it only on my guitar, not all outs?
These could be really stupid questions but sometimes I get lost in audio routing, and these are somewhat deciding factors in my purchase.
I know it's not quite DJ related (looking to develop ambient/drone/post-dubstep live-set) but I figured this is the gear community , and I value you're opinions

Anyways, if this needs to be moved to music production please do so otherwise, lets hear it!
Thanks
