Another Ipad recording question

[RAY AGAINST THE MACHINE]

Okay, when I bought the above, I was the big kiddie in the sweet shop, buying numerous'useful 'apps.
I'm enjoying the kaossilator for ipad, plus various bits from Moog , Alchemy , synth station etc.

I understand Garageband, but can't seem to record more than a minute or so. Any ideas how to extend recording time?

Also, is it possible to have the kaossilator (or other apps) going direct into garageband , so I can play along
with my bass etc?

Please advise

cheers

Guess I could've asked the question in a less complicated way: can I use more than 1 app
at the same time on iPad?
