Lets use the term transfer vs. load
Currently I can transfer a sample from a floppy disk in to the sampler on my SD1 in a matter of seconds.
If you have a sample on a memory stick, it will only take a few seconds ...
Any audio samples that are associated with style play with the Audya will stream from the hard drive, when the style is called up.
Any audio samples form a different source can be transfered in to the sampler in seconds.
If you wish to use the sample with a style, you need to slice it to match tempo of the style you are trying to create. Once you have done this, you transfer the sample to the master folder that controls samples..
all transfering of samples from sampler to hard drive is done internally in seconds.
