Creating a drum loop is a good way to start writing a song. It provides a good base to build the rest of your song from and is much more inspiring to work with than just a click track.
In this video lesson Victory Pill's Pete Crossman shows you how to build beats using individual samples, some layered, and audio loops. He shows you how he enters drum hits via his keyboard and quantises them. He also shows you how he slices audio loops into their component parts so he can edit them as he chooses.
You can also watch MusicRadar's video lesson of Jim and Pete showing you how they use compression to control drum loops and guitar parts. For more information on Victory Pill visit the official Victory Pill website or the Victory Pill Myspace page
