Okay ill try and make it brief.

1) I got my 2KXL and I have a Roland JP8000 synth. Now i was wondering which is the best way to run all my stuff in a live stituation. Im playing all this stuff in a band and i was wondering would it be best to invest in some PA speakers and an amp or something? Or is it best to run direct through the clubs PA live? If i run direct or through whatever, should I also invest into a mixer to run all this??

2)Okay someone told me recently that when i get my 2k that i should invest in a PC editing program like Cakewalk or Acid so that I could edit my loops and then dump them back onto my 2k because the editing capabitilies are somewhat limited on the MPC. So how exactly do theses programs work? How do i transfer my loops from my 2k to the computer to edit my samples?

If you can answer my questions or can tell me anything to help a rookie out thank you very much! =)
