I'd have to +1 for a larger case as well. Having done live techno back in the 1990s (without a DAW, I should note), one method that I found very workable with my Digisound/ARP 2600 combo that I was using at the time was to set up multiple parallel "instruments" within the modular architecture. New track? Just fade in another mixer channel and fade out the one I was on. While the hardware might be rather different here, the method is still quite solid, but it does take a bit bigger build to accommodate several separate audio paths...plus having all of these intersect at a proper stereo performance mixer (which I didn't have back then) is super-helpful.
