Audio Studio in Ubuntu

I'm going to use an Ubuntu system to do some audio projects, so I wanted to figure out how to use Jack and some other applications that come with Ubuntu Studio.

Jack Resources:
Ubuntu Wiki - preparing a studio computer - includes help on realtime settings
Ubuntu Wiki - Howto Jack Configuration

Ubustu - How to configure Jack

Linux Journal article about Ubuntu Studio setup

Supercollider resources:
Tutorial for installing SuperCollider on Ubuntu
Apt Repository for Supercollider
Using the SuperCollider plugin for the gedit text editor
SuperCollider swiki

*update* My computer won't boot with Ubuntu Studio 9.04's realtime kernel (linux-rt). Other people have a similar problem. Discussion threads have had success with a custom kernel build that I will try out. Instructions here.
