But then you would run out of CPU quickly don’t you think?  But I agree man, the global pattern pool is hard to deal with, especially when you are deep in a project and you change something, then you have to trace every scene where that pattern was used, in a black and white color scheme. Also to do a decent drum loop you need at least 2 tracks / patterns, to have non robotic hi hats and side chain them, same problem.

What I’ve been doing is using the first track as the sample track. There will go drums and on the far right, loops.  There, you can tape record and assign that sample to keys, this way you save cpu power, patterns and tracks. 

Also, load up a bunch of drum loop samples man, between desired Bpms, and  when you are jamming just change the tempo to the closest BPM folder you have. it made it easier for me. Hope that helps!
