Renoise can seem a little overwhelming at first, so this tutorial series gradually works through the most important steps in song creation. User interaction is emphasised very early on, since getting hands-on with pushing buttons and making sounds is one of the best ways to engage and teach a novice.
The tracker interface is what separates Renoise from other Digital Audio Workstations, and Redux from other plugins. Effect commands are a large part of that, but can seem alien to those unfamiliar with trackers. This tutorial series explains each command and demonstrates how they can be used.
