It's the popular practice for a subbass wobble.

You could also try more of a reese sound (detuned saws), and modulate the lowpass. Or pulse-width modulation.

So can tremolo be used instead of having to actually having to automate the volume directly? I know they are basically the same thing but i'd find it easier just using tremolo

filter cutoff is a frequency. frequency is a pitch. i suppose that is different from modulating the pitch parameter itself with an LFO, which is possibly the source of this confusion? but the filter is cutoff at a certain frequency, and therefore at a certain pitch.

thanks for informing me of the use of LFO on volume though!

How did this make it past 5 comments?? Lmfao! There's only so mich on a sub you can modulate without it getting muddy.
Filter cuoff is determined by frequency, but doesn't change the acutal frquency of the sound, it just filters the frequencies and adjusts the sounds timbre according to where it's set, ie: Low Pass at 500Hz only filters everything above 500hz.
Pitch in the other hand is essentially the actual pitch of the sound, ie: the sound hitting at 700Hz.

Example: modulate a pitch drop with a sub and you'll have the cool bass drop effect... Now do the same with the filter cutoff and you'll see it's very different, the filter cutoff mid might be cool for like a sub fadeout effect...

I don't personalyy like how a sub sounds with it's cutoff modulated, if I want it to follow a wobble or something like that I modulate the amp, but only very slightly!!!!! I usually use 1 clean sine wave, if you notice on a spectrum, the note you hit is the most pronounced and every "harmonic" (heard/seen tones above the fundamental) above is barely heard and you are really only hearing the nore you hit, now when you go to modulate the cutoff, the note you hit will get much weaker as it is being removed, depending on speed of the modulation.

And ps: sub is meant to be heard, not just felt. YES, YOU SHOULD FEEL IT AND IF YOU DON'T FEEL IT, IT'S NOT A GREAT SUB. The human hearing range is from 20Hz to 20000Hz and you always always always hear the sub, at your desk, in your car and at clubs/concerts, you only don't hear it in crappy headphones, but even then you do because they saturate and compress the hell out of it for mp3s and such do you can hear everything everywhere...

This is seriously like a primary school music lesson. No filter cutoff is not pitch, it has nothing to do with pitch. Just because it has a frequency does not mean you can call it pitch! I seriously cannot believe some of the stupid shit I read on this forum lately.

alright VirtualMark, I'm sorry.

in practice, not knowing the difference between frequency and pitch isn't the end of the world. you love showing off your superior theoretical music theory knowledge and your parents probably bought you piano lessons from the time you were 3 years old. not all of us are that fortunate and we are trying to learn this stuff now. so fuck off.

Lol

And btw, a sub bass is usually a sinewave, meaning it hits at a specific frequency and that's it. No harmonics or anything. So modulating the cutoff of a filter doesn't make specific sense. It's just the same as modulating volume, since the sound is only composed of 1 freq.

my god it still baffles me how much people don't know about sub bass on a fucking production forum of a genre based on the sub

let's just assume you have a single sine wave sub for purposes of this explanation
this is a SINGLE FREQUENCY at a single point. there is no low passing or high passing! if you filter over this frequency it is GONE because there is nothing left to it. no sound below it, none above it.

the only two ways to automate a pure sine sub is the pitch or amplitude (volume)

OP you're looking to automate the amplitude. adjust how much to taste

lol we posted nearly the same exact response at the same time

so you felt like jumping on the bandwagon but didn't have anything to say?

I didn't know shit about music until a couple of years ago, everything I have learnt has been in the past few months. It doesn't take a fucking genius to work how to search google - I even provided a link for you.

Search term - "pitch", OMFG that was hard.

Perhaps you find it easier to just come on here and spread nonsense, that seems to be the way it is lately. I don't claim to know everything, I just try to learn. I did learn some stuff from this forum when there were helpful people here. But seriously, it has dropped below the bar lately, people can't even be bothered to look up the ABCs of music now, they'd rather argue about it on here.

And if you're here to learn, WHY DO YOU KEEP GIVING OUT BAD ADVICE?

EDIT: Don't worry charles1, I won't help you for free anymore. You can continue your delusions, I'm kinda tired of trying to help people and getting shot down for it. The only reason I post is to help spread accurate knowledge so that others can learn - that seems to be unwanted in the production forum. So who am I to disagree?

Sometimes modulating wet/dry on saturation or distortion on a sub can be cool if don't ming losing power.
Modulating to another waveform is kinda cool if your synth has the capabilities but is usually technically just another volume automation.
I guess they kinda become less like subs in these cases though.
but really volume, pitch, and portamento is where it's at.

Just go experiment and learn your production vocab and look shit up.

again and again, you think I'm trying to give out advice....

when I'm not.





again, in practice, not knowing the difference between frequency and pitch is not that big of a deal proportionally speaking to how much you flamed over it.

VirtualMark wrote:Search term - "pitch", OMFG that was hard.

yeah, cause when I'm sitting at my computer making music, ya know what question I'm just burning to answer for myself? what is the technical difference between frequency and pitch. seriously IN PRACTICE, not knowing that makes little difference. It's not like that little fact is necessary in order to make music. It's more suited for a trivia question.

Efrafa11 wrote:Sometimes modulating wet/dry on saturation or distortion on a sub can be cool

for sure, I sometimes 'bus / send to group' the sub, give it mild distortion then hi pass the sub out. gives it a bit of character and leaves the original sub clean.

Really?

Sounds like you trying to tell people how it is to me.

I don't think I flamed you that badly, I honestly couldn't believe that someone would argue that a filter cutoff is a pitch. And we weren't arguing about frequency vs pitch, you still haven't grasped it.
