if i understand what you're saying, then...
the bottom panel (1-8), (9-16), or ALL studio view is for the creation of your own instruments. so if you load a clap sample, into say pad 9, any changes you make to the master, filter, or parameter settings means you're actually designing a new instrument which you can name & save. so in the bottom panel you'd have to individually click through each analog, physical model, or sample as this is more of the "sound design" process.
now in the center panel when you select a pad, say pad 9, and you use the jog dial you're scrolling through all of the saved "instruments." (the jog dial can also be switched to load up complete kits or projects). so if you spin the jog dial then you may start off in the Bass Drums, Snares, or something else, but if you keep spinning the knob you eventually will
find those claps and then you just have to click the dial to confirm the change.
you may be confused when you select pad 9, turn the jog dial, and discover you're in the CH (closed hat) or other section for some reason. as i said eventually you will see the saved "instrument" -- claps (or FX, SD, Crash, or whatever you want) that you were looking for. the reason it currently doesn't start off in the "correct section," i think
, is due to a what must be a bitch of a bug; it's what i'd call the "New Project" bug. i say it must be a bitch of a bug 'cause it's been around since the early Betas and it's still listed in the To Be Fixed section: http://www.arturia.com/evolution/smf/index.php?topic=4502.0
you'll notice that there will be a "New Project" bass drum, snare drum, and everything else "New Project" that would make up a whole kit when you scroll through the jog dial. each of these "New Project" instruments i think have shifted the numbers in the listings a bit.
