I used to make my own SoundFonts... It was easy. Just take about 10, 44.1 recorded samples--- e.g., your own vocal "Oohs" and "Aaahs"--- and plug them in to be distributed over your keyboard's range. I used ALIVE!, which made it pretty straightforward.
How are YOU creating your own, personally recorded, multisampled patches these days? (Of course, it's easy to simply plug in one single WAV, and have a softsynth distribute that one WAV over the key-range, replete with chipmunks and Darth Vader, but I'm talking about a multisample). What software do you use? Is it easier now, or harder to do?
