There's pretty much none that I can think of off the top of my head apart from that that one Pulse X one. Wouldn't mind seeing how other's work though. My shit is structured terribly with patterns everywhere but I've always managed to work like it.
I often watch production tutorials to pick up tips on how producers approach drum patterns/Basses/Effects etc.
However I don't know of any that are specifically grime orientated.
If anyone does, or knows of any that would benefit grime producers who are inexperienced like myself...come through.
There are a few off the top of my head;
Mr Wong from Risky Roadz
Mr Slash and Skitz Beatz from PHTV
Teeza, Swindle, Spooky and Lewi White on Beat This
Not enough though but actually that works, because some really good production techniques can be learned from looking at the dubstep, dnb, hip hop and house tutorials that are about
Music is music my man, do what ever you feel like doing. The best thing you can do is learn about production tbh breh.
