As a part of a commissioned tutorial for a dirty south-esque beat, I made a pitched snare roll, and thought it’d be useful to make a video just for that effect, since it’s quite popular, and most people on youtube tend to use automation for it instead of the NN-XT sampler, which I think is a long winded way to make the effect compared to my method.
It uses NN-XT, MClass compressor and a bit of RV7000 reverb. A nice, quick tutorial for you! 
Video could not help me. I did everything you did but the snare was not rolling like urs was. I feel there’s stuff u miss that u for got to tell.
