[linux-audio-user] Using Linux Laptop for Live Performance

Hello Folks; I am a linux enthusiast, and software engineer who would like to start using my Linux laptop as a live performance tool. I am a bassist, and want to be able to process, sample and loop my instrument through my laptop in a live situation. I am just beginning my research into the available software and hardware, and would greatly appreciate any information. Especially on hardware - what would be the best usb/ firewire interface for live performance? Following is my setup: Alienware m-51 laptop w/ 1 gig ram, 40gig hd, 3.24 mhz intel processor 7-string MTD custom fretless, strung B-E-A-D-G-C-F Some stomp boxes: MXR Stereo chorus, Boss RC-20 loop station, Old Roland Phaser At this point, my idea is to string it up like this: Bass -> Stomp Boxes -> usb/firewire interface -> Laptop -> Amplifier / PA Thanks for your time folks - I look forward to your reply! vic
