GIGASAMPLER
My home recording studio had the registered version of Nemesys Gigasampler SE 1.64 with Gigapiano.
I worked on this sampler a lot, and dig into all its feature. I wrote a complete tutorial in 11 lessons for this program, originally for Simonazzi Federico's Alar Recording Studio (Parma - Italy). The tutorial was translated in english also, and you can finally read it on my pages, simply click here
Generally, I use Gigasamlper for handling bass and drums parts, since with it i can use really huge sample patches, without having memory problems. For example, my Bob Clearmountain drums occupies 18MB (only toms) and 75MB (only cymbals)!
I set-up a bass patch with some innovative characteristics. You can find a description of it at my tutorial page
