About eeepc, 32 bit and looping

Hi everybody.
Since I switched to Linux music production and performance, I decided to do *everything* Linux-only.
I gave a new life to an old eeepc with RAM=1GB and a 32 bit processor. I removed Windows XP and installed Lubuntu + low-latency kernel and Jack.
I want to launch some loops from it, could you suggest me your best choice looping application) I decided to use LuPPP but it's 64-bit only.
Giada is minimal and functional but sometimes it crashes.
Any suggestion?
Thanks!

ps: I already installed Qtractor and it runs ;)
