Reply to Kontol S4 + Midifighter questions

Hi All!

I'm hoping you guys can answer a couple of questions for me to help me work out a live setup.

I currently use Serato + control vinyl for traditional DJing, but I want to build a live performance setup for my own material that still keeps a loose "DJ" format. I'm looking at moving to Traktor and the S4, but since I don't have Traktor I'm not sure of a couple of things.

What I want to do is:

1. Load up my own multitracks (songs split into drums / bass / vocals etc) and play back, loop and apply FX to those sections.
-> This part seems pretty straightforward with the S4, having 4 decks to play with.

2. Record loops on the fly, including live stuff through a microphone.
-> Again, this part seems pretty straightforward with the S4 and Traktor and perhaps a footswitch.

3. Play back single hit drum sounds using a controller during certain sections, and build up live beats via loops.

This 3rd part is where I get a little uncertain. Do you believe getting something like a MIDI Fighter would be suitable for that kind of thing?

I understand that Traktor has one-shot sample banks and I assume that I could map the MIDI Fighter to play back those samples. My concern would be how easy it might be to switch the sounds loaded in those banks from track to track in a live setting. I don't want to be touching the computer too much.

Is there a better way to handle this kind of task through Traktor? Maybe putting in a naked kick, snare, hi hat etc sequentially on a single track, like a battle record, and then triggering the sounds using a MIDI Fighter via cuepoints?

Is triggering cue points using a MIDI Fighter responsive enough to to build drum tracks on the fly like this?

Might it be too CPU intensive to be jumping around cuepoints so much on a single track, whilst simultaneously looping and playing back other tracks in Traktor?

Would I be better off getting Maschine or an MPC instead and using that to handle live playback of single shot samples?

Hope you guys can help me out here. I'm just at the stage of trying to work out what's possible at the moment.
