RE Prosonus, read Lifeforce\'s post, Donnie is very helpful with the descriptions.
As far as the editor, look at Dave Govett\'s posts. He\'s resolving it RIGHT NOW! (Thanks, Dave!) There\'s a lot of grief has been poured into these pages about that, but that\'s about to change...
Giga doesn\'t respond to all \"standard\" MIDI controls. But most of them are in. Stuff like the 70\'s (brightness, attack, etc) are set in giga as standards (oh how I wish). You can however controll most of these in the editor. Brightness can be controlled by a low pass filter which can be mapped to various CC controls. Attack, Decay, or Release (or combinations of the three, but not seperately in this stage of giga), can be mapped to various controllers as well.
I find the editor to be one of the easiest things to learn by jsut diving in. If you are familiar with ANY type of sampling terms you should be able to get in there and know waht you\'re doing. Heck I had no real experience with samplign, and I jsut dove in. Its pretty simple, IMO. Tho it is frustrating once you realize some of the editors limitations. which of course I find insteresting at the same time since it makes me think of ways to get aroudn the limitations.
\"Tweak\" - to make small, subtle chjanges to something. In the case of GS, it might mean changing one CC for another, or tuning a note a few cents, or just changing an envelope attack slightly faster or slower.
Good Luck - I used to have King\'s attitude of \"just dive in, it\'s really not that hard\" but for some reason, GS has too many parameters I\'m unaware of, and I don\'t have time to go through that kind of learning curve these days. Dave Govett, c\'mon, baby!
