Best iPad Music / Looping Apps

[Christopher Darrow <thedarrow@gmail.com>]

I'm sure this has been covered so forgive me for not researching but I'm 
about to leave for Burning Man and bought an iPad 2, partly to use as a 
sound source for my EWI (Electronic [MIDI] Wind Instrument) and I have 
neither time nor money to investigate on my own. 

I can afford only one or two apps (and truth be told, not even that... for 
the moment anyway.)

1) What's a great sound source, particularly for realistic sounds, such as 
stand-up bass, etc.? I can't stand, toy like sounds, especially piano, 
violin etc.
2) What's a great looping app and doesn't it also have to be the sound 
source app? (Isn't it only slight-of-hand multi-tasking, not true 
multi-tasking---for most apps anyway... plus you'd have to switch from one 
app to the other. So I just don't know how this works, but it must because 
I've seen calls from developers on this list.) I'd like to be able to set 
up the low notes on my EWI to trigger loop functions. And multiple loops, 
overdub, undo. Other then that, simple works fine. I guess a drummer 
function would be good too, if it doesn't suck.
3) What else should I know or think about or check out?
4) My plan for protection from dust is to wrap it in Saran Wrap. If I'm 
not mistaken, the touch capacity will go through it and I see no vents on 
the iPad so heat shouldn't be an issue. Right or wrong? Other thoughts?

THANK YOU for your time responding with any suggestions or ideas.
