By grasping the concept of velocity layers in a sampler you will be able to better use and more easily create your own dynamic and exciting sampler patches. Digital samplers, like Reason’s NN-XT, are an essential tool for creating your own unique sounds and audio effects (such as stuttering) and have been a secret weapon of hit producers since the early 80s (especially in hip-hop and dance music).
In my Producing Music with Reason course, I have an entire lesson dedicated to the NN-XT Sampler. It’s that powerful and that deep to warrant a whole week of study. Yet, the assignment at the end of the week, to build from scratch your own NN-XT patch, is for many a serious struggle. Consequently, the way I figure it, I can’t have enough material explaining the finer points of the NN-XT. That said, here’s a video tutorial I did on understanding the power of velocity mapped zones in the NN-XT Sampler.
