Op4x

Right I don't understand FM synths any good resources to get my head around this, I've watched many videos trying to understand how this works and I get the flow of what does what but still trundling to get what I want.

I primarily make DnB and after hearing a Nero tech example on YouTube I belive its just my understanding of this thing.

I came from Massive and Serum and they are so visual it make it really easy to get around. Does anyone else make those type of noises that are willing to share a few presets?

I spent ages trying to make a Reece Bass then found one in the presets and I've a while playing with it and it was allot simpler than I could have imagined. So any tutorials people recommend doesn't need to be for OP4x but if so it'd be better....
