Do you mean because of disk caching?  If not, then it seems fairly 
complicated to create a whole new all-file-loader/memory structure for 
each type of file.*  The beauty of a ram disk is that it the file 
addressing is exactly the same.  In fact, I just now set one up in a few 
minutes, and it works wonderfully.  I can change sssad presets, or 
[tunetof] tunings, with nary a glitch.  Of course, it won't work for 
files big enough to take more than one dsp block to load from ram -- 
that's a big limitation.


* I imagine this working by pre-loading everything in a given directory 
(or listed in another file, maybe).  Storing, then accessing and copying 
that information live doesn't seem trivial, to me at least.
