the pattern change should be pretty straight forward to set up. see schnorks excellent post above. i think this will make live performance easier.
with a performance macro you can change different parameters in different amounts on different tracks by the twist of one knob.
this is extremely powerful.
once you have it set up on both machines, ask again and we can link the performance macros of both machines together…
an examle: with the twist of one knob, you could: fade/filter out the kickdrum, put a massive delay on the snare and tune a sample up 5 semitones while make it decay longer on the rytm, while on the ak one track sound can be turned down completely and a drone on another track could fade up. while making the delay time longer and open the filter… and that would be just one knob (macro) 
edit: load the space disco in the ak factory presets and turn the perf macros…
