YEah Youtube made it even harder for smaller channels :(
But thank god we got Steemit and Dtube :D
Mk3 is great, i ve been using it daily from September , and like you said, there are so many possibilities, that you can learn something new everyday :)
To be honest i dont use a lot of sequencer , so i cant help you with any info about that . But i think its awesome that one Controller has so many diffrent possibilities , and almost everyone uses it in a slightly diffrent way .
Thanks for watching, and more to come ;)
