Bass Drops

My son wants to add some "Bass Drops" to a metal song he's working on. Does any one know if there are such things in the extra content ofx2 producer? I've looked a bit in the one shots and some loop stuff but there's so much of it I need a shortcut. This may be achieved with a soft synth as well, it's just not my territory.

Are there any tutorials for those synths to create the drops?

This is not the best tutorial, but it gives you a basic idea: http://www.youtube.com/watch?v=Uxfm26TGjlc
 
For the most part one is creating a bass and tying the lfo to the cutoff while automating the rate.  This tutorial sucks, but the instructions on other tutorials apply to all subtractive synths.  There are also presets included in Zeta+2 and some great lowcost preset packs from Xenos sound works and a few others.

personally, i found pentagon was the easiest to get the desired result because of it's simple interface in comparison to the others.  Z3ta and Raptiure are , imho more capable of creating more complex and grimier sounds.

What is a bass drop?  That is a new one for me.

I'm pretty certain he is referring to this:

Similarly heard here (0:08 and 4:08 marks):

Is regularly found in modern metal, though seemingly a "trade secret" on how exactly to produce. I've come across one or two little VSTs to do a fair job (Subatomic comes to mind), but it may be the case that creating the bass-heavy sine wave from scratch would offer the best result when done right (though I can't say I've yet done so myself).

This is a better example:

I have just had some experience with this as I am producing a track right now which could be described as aggressive hip hop and the singer wanted some bass drops in the bass line so I had to figure out what she meant and do the research.
 
It is more an aggressive bass sound and it can be programmed from synths like NI Massive. (And many others I am sure) There is often some fairly severe effects that are applied after the synth too. But there is a simpler way as well. If you have got Camel Audio's Alchemy or the Alchemy player they have a great library called Dubstep and all those bass sounds are in there. The MixPads allow for some pretty wild operator manipulation too. They rock!

Konrad,  keeping up with the various terms thrown around in various sub-genres can be a challenge and you will encounter variations in meaning of the exact same term.  Most of the time , the "drop" refers to a moment in the song where some variation of section extremely heavy on bass.  Typically it will follow the intro in genres like dubstep and repeat at various intervals.  Sometimes it will be during chorus like in the pop song "Too close".  The exact sound varies and has evolved over the years from extreme sub-bass wobble bass to more screeching FM synthesized bass at a higher frequency.  The examples given should give you and idea of the various ways a "drop" is implemented.
 
Sine waves are not typically used for this sort of thing except for the general adding weight to the bass you described.  Most bass of this type is typically done with saw or square waves or some combination of waves with lots of dynamics since it will be heavily filtered.

Exactly dimelives1.  I was thinking about recording a "drop" old school style with a bass guitar and working with some octave sort of effects. I think it might be more original sounding than copying sounds from the herd

dimelives, thanks for clearing that up.  I have to listen to your examples on something other than my laptop or cellphone speakes because I don't really hear anything.  I suspect it may be beyond the range of these speakers so i will listen later.  I don't listen to enough metal to know what to listen for.  I do remember dimebag Darrell, so I'm not totally hopeless lol

Oh yes - subwoofer is a MUST to fully grasp what is being referred to here haha. And good on ya for remembering Darrell! The metal gods will be merciful upon you ;)
