*edit*
So I just wrote a thesis

... in case you can't tell, I am really in overload at the moment. . I can't stop thinking about something related to this at the moment... I feel more driven than I ever have before... back to making samples in Live. .
PS: Keep an eye out in the library, I'm going to upload a bunch of multisampled instrument/synth sounds for y'all soon that I'm preparing for getting my new SP-404.
OK. . .so the KP3 cost me A$700 . . u can get em round $750 most places, I managed to trick em into promising me one for $700 before they checked their prices...
You can't produce with it. . . I mean if you were *really* tricky you might just about be able to make some weird ambient-glitch-noise with it.
It's real strength and use is in live performance as a looper and effects box.
you could almost do a full live jam with it on its own if you filled the SD card with loops, except you have to stop all 4 of the loops from playing in order to change any of them (if you're loading them from SD card)
If you have either a) some other sound source or b) 2 KP3s,
you could do a full jam with them - because you can record a new sample in realtime without stopping.
The effects unfortunately apply to everything coming out of the KP3 rather than being routable, but they're stilll really cool.. very crazy over the top fucked up stuff mostly.
granular effects, more looping, bitcrushing, vinyl-speed/slow/revers type effects, some good basic delays, filters, reverbs too.
you can control the volume of each loop playing, so use it as a mini 4track, and if you solo one of the loops, you can resample it including effects.
Back to the rest of the rig... I'm not going to get a machinedrum, or anything that expensive for now (if I ever could afford it, I think for expensive gear I'd get the jomox xbase 888/999. . basically just for analogue kick + toms)
I'm pretty certain the following will be my exact rig, I've made 'mockups' of each piece of kit in ableton live and using my midi controllers and have been playing with it for a while... Its not overcomplicated, heaps of fun, very immediate.
My next addition will be an SP-404,
I'll use my M-Audio Axiom25 to trigger the 404 (gunna have some banks loaded up with octaves of pitched samples)
some of the more complicated bits will be pre-prepared as patterns on the 404, but the rest I will just wing, to keep it loose and a bit more raw... Drawing alot of sounds/influence from techno/minimal/progressive, but dont want it to sound so mechanical and clean.
After the 404, the next on the list is a DSI mono evolver
(man I am really regretting selling all my gear... I had an sp-404, a kp3, and an evolver once upon a time!!

)
The evolver will serve 2 purposes... first, obviously, as a synthesiser. If you're sneaky you can get 2 mono parts out of the evolver - because each side of the stereo system has its own oscillators..
The 2nd reason I want to get an evolver is to 'fix' one of the limitations of the 404... the one that really bugs me the most - lack of amp envelope for samples! I can use the triggerable envelopes ( and the filter/filter env too!)
Once I have the evolver, I guess I will add a small mixer, to give me more routing options for effects.
Also I already have some cheap effects pedals I'm using too (behringer reverb, crossfire delay)
And that will be all really.. Im' going to make it small enough to fit in a briefcase and build rechargeable battery packs for it all.
Then the true work can begin...
Armed with my briefcase (+mic + headphones/amp).. I plan on finding an abandoned/overgrown/derelict location.
Sampling on location and producing music onsite. Bringing a few arty friends with me to 'augment' the area.. (rather than completely alter it.). . into some kind of. . magical, surreal, psychedelic fantasy version of the place
Then once the music is done, and the artists have worked their magic on the location, I want to have a party at the place. . my music + other peoples too. . live art. Nothing big, just say like 10-20 or so like-minded friends,
all in an attempt to transport everyone into a completely immersive fantasy.
maybe do the creating at the same time as the party, so that slowly the place becomes more and more twisted as our minds do?? But yeah...
LSD WOOOO!
The end. No you can't have the time back that it took you to read all that rubbish!
Samples.
