Kinda building on the other thread about doing a Massive tutorial, I think S.A. should bridge out and have a whole synth tutorial series. Reaktor was great! Something like that for Massive, FM8, Zebra, Operator ETC.
I could be broken down into 2-3 parts, with each part getting deeper and deeper into modulation possibilities. I love these tutorials because it save sooo much time learning new things.
