DIY 4-Track Looper w/ Raspberry Pi | Building a Loop Station

The process essentially involves connecting a USB sound card and some buttons and lights to the Raspberry Pi, then downloading and running a Python script. I think this would be a relatively simple project, well suited in particular to people who are new to electronics but have some experience with Linux.
