Sustains in Serum THE EASY WAY 

I use vital but pretty much what I got outta this is find a buzzy or vowel like wave table and that will be the lead harm wavetable. And runn a second Osc as a basic shape like triangle or squares wave or sine whatever to add more timbre u combine them. Lfo shapes should be more like 24db filer cutoff shape per say. Run lfo through a filter like a comb filter.. Maybe run fm synthesis, Find the sweet spot. Macro tht junk. Mess with specteral morph settings. He's kinda just giving u ideas on how to make those type. Not really a full on a,b,c,d

Sustain refers to the part of a sound's envelope when the note is held. When a sound has 0 sustain, then the other factors of its envelope essentially react to note-on as a trigger, whereas a higher sustain value lets sound through (at a certain level) as long as the note is held. If you wanna learn more, read up on envelope generators (ADSR) in synths and the difference between staccato and legato in composition.

@@turbochargedfilms thank you so much for your time mate....😇😇😇

You can set the Lfo to envelope also

@@raincaster1295 yeah exactly just use the saw up shape so it doesn’t drop at the end of the lfo envelope
