Audio Effects
Renoise currently offers 22 built-in audio effects, which can be applied as Track DSPs on any track. All Renoise in built effects are guaranteed to be included with every Renoise installation. So you can be sure that others can play back your song in their setup just like you can. This is not the case with plugin effects or instruments: Audio Plugins like VST or AU or LADSPA effects are optional components which have to be installed on the system first, which makes sharing song files harder.
