I've had my Triton for a while, just never really delved into some of the more advanced things. Just played it with tweaking a few parameters. So, I'm not a total newbie

Anyway, I had a couple of questions if someone could help me answer:
1) is there a parameter editor/librarian for the Triton? I'd prefer a ProTools plug in so I can do it on a session by session basis. I've seen MidiQuest and Unisyn, but I was hoping for something a little cheaper (or free). I'm also running Mac OSX 10.6, so Unisyn is out anyway.
2) i've seen all the various PCG files available. Is there any tool (possibly combined with #1 above) that can load them via Midi SysEx instead of disk? Looking at the SysEx implementation, it seems like it shouldn't be very hard to do. It would also let me just have the files on my Mac to upload on demand.
3) Is there that much of a performance difference in upgrading the memory?
I probably will have more questions, but that's all I can think of for right now
