umm how the heck could you beatmix a track that changed tempo??
same way that a pianist can play many melodic lines at once as voice-leading and bring out the expressive melody within each voice. Practice, performance technique, and the best instruments. I'll add my two cents. Electronic instruments on the whole are very very primitive in terms of the quality of the interaction with the player. We have immense amounts of sound manipulation at our disposal, but the actual interaction is primitive. Lets take your example, mike.Say you want to beat-match tracks with changing tempos.
there are some key concepts which are missing in most modern interfaces which need to be addressed if you want to do this.
1) haptic feedback (the sense of touch)
Lets add some haptic feedback for those tracks, for starters. What if you could run your hand along a length of interface, and feel where the bumps (say of the kick drum) were. Now you can drag around these drags, with the feeling of where you are in the tracks.
2) Testing the waters
Most synth technology only allows you to hear the note once it has been triggered. We want to hear the sound/ feel the impression of the note before it sounds. Sounds like a Zen statement, but in most accoustic instruments, you get a lot of feeback about the note before you play. You can feel the strings, feel the frets etc. What if in our example you could 'feel' along the sample to get a sense of where tempo is changing before it comes apon you?
Another aspect of this is controllers. Say you have a parameter like a knob assigned to linear pitch adjustment. you want to take the whole track down a tone, well without being able to 'feel' where a tone is, you need to play the track first, what if you could 'feel' virtual notches for note pitches?
Or to touch a drum pad to feel when it's notes are firing, without needing to actually play the pad.
This feedback could be visible as well (at the p.o.i) or even -gasp- audio.
3) Closing the loop
Electronic instruments need to give better feedback to the performer AT THE POINT OF INTERACTION. Maybe your synth is running out of polyphony, perhaps that should make the notes harder to play.
What if live is about to change sections. could it 'tell' you in some way? a slight effect on the main audio out that only you would recognize? Or a language/ sound world that gets sent to your main cans? after all, most acoutic instrument do produce some acoustic noise like key-clacks, etc.
IMHO the actual sound producing end of the interaction is quite good. the problem is that we get little feedback from the machine at all.
