Yeah but what we're saying is what are you talking about using it for? Thats like asking how to design a house without knowing how many people its for or where it's at etc...
If you're talking about DJ'ing, though, I use 4 slots in session view. 2 slots = one deck. Any track I might want to use for DJ'ing, I'll warp, find the key (by ear... don't trust Mixed In Key type software), then make the song into a few clips using follow actions.... Since a "deck" is 2 slots, in the left one I will make a seperate clip for each verse and then put a looped version of the chorus on the top. So I can use follow actions to play a verse, and after it's over it goes straight into the chorus and loops. Then on the right half I make another stack with just different loops I've pulled out from the song. After I get it set up the way I like it, I just highlight the clips and drag them into my library and it makes a nice single .als file that I can drag into my set and have all that ready to go.
For midi, I have a UC33e that has 8 tracks (8 faders and 8 sets of 3 knobs). So each track gets two tracks worth of controls on the UC33e for effects, levels, etc. Usually since it has 6 knobs, those are for hi, mid, lo then 3 x effects. The axiom 25 has 8 drum pads so 4 of them launch clips in the 4 different slots, and the other 4 stop them. It has endless encoders that I use to navigate around session view. Different keys on the axiom keyboard control loop start/stop and on/off, Waveform view, etc...
