2:50 you can make any sound velocity sensitive in serum by dragging the Velocity envelope to the Volume of your main OSC. Turn the volume all the way down and then turn the A Vol Knob all the way up. The drawback is I believe you can only do this to one OSC so if you have a sound with 2 OSC welp... lol
Dope video bro🔥i really like your style you are a talented producer but i loose attention often and i think thats because you speak very mono tone. I used to have the same problem but i worked through the habit so my advice to you is take confidence in your talent and yourself. be more enthusiastic and less mono tone with your videos and i thibk that would improve your videos a bunch
