Problem with "going legit"

[wirez]

Dep, I've got a little Logic question for your wise ass...

Sidechain filtering... How?

Say, for example, subby kick, subby bass... When subby kick plays I want subby bass high passed...

Can't seem to work it out? And automating is it long!

Not sure if i have seen an EQ or filter with sidechain input (i think ableton has one).
What i would do is split the frequency via either a linear phase EQ or i prefer to use logics multi band compressor, with no compression but soloing just 2 bands. very handy tool!. So on the sub split, you have band one solo'd, and for the mids/highs solo the other band solo'd

Then just use regular sidechain compression on just the sub band. make sense?
Scrap that im gonna make a template and show ya

Nice one dude!

ok its pretty crude, but you get the idea of how i would personally tackle this. http://www.mediafire.com/?ygnlqjtmm5f

Cool advice. Never used the multiband compressor. Then, I've taken years to get to grips with just the normal compressor

Hmmm it's no so much the effect I was looking for but I can see how it could work and be sorted out to achieve what I was trying to... It looks a bit too much hard work to set up really though, I think I'll have to stick to the automation when needed for now. I find it strange that Logic didn't make their hi/lo filters sidechainable though... The only other way I could think of it was through the filter on the noise gate?

im using the MB compressor as a splitting utility though, iyts not actively compressing anything. the threshold is set up high and the ratio on nothing, its just the frequency splitting part of it im using.

Thing is using a filter set to a sidechain input would really mess with your phase response. the levels will hit the ceilling. for example, put a hipass filter on a sub, move it up to say, 35hz and the signal will now be clipping. Try doing that to a sidechain or even an lfo envelope and your running into all sorts of problems. Hence why i tried to split the frequency first before sidechain compressing the sub bass. I think theres a reason theres no sidechain available on filters. Correct me if im wrong.

Hhm I'm confused. If using a filter with as minimum resonance as possible, why would this cause an increase in levels? Also, why would it cause phase issues if I'm completely cutting out an area of frequencies from some audio because they're being used elsewhere? Essentially all I'm trying to do is high pass a sub bass when a subby kick is playing, as you know.

If there is no resonance on the high pass filter it shouldn't make much of a difference when it's moved up to 35Hz on a sub, from my experience... Say for example you used the 'Low cut' on Logic instead of the 'High Pass' (which has a resonance setting, unlike Low cut) the filter should essentially cut below the designated frequency without boosting around the cut off point and increasing the gain.. Is that what you're saying? I'm confused

Macc Knows all!!! (also did a brilliant job on my latest pieces)

look here. Its not down to resonance but the way that EQ effects phase (after all thats what its doing to effect the audio)

Fuck sake man, I just want to make tunes... This intense science/music connection never ends hehe... Reading into it now

Not true at all. A sub is a sine wave, a single frequency. A sine wave through a filter gives you a sine wave at the same frequency, with a different amplitude and phase (delay). The only reason the new sine wave would have a bigger amplitude would be if you used a filter with a resonant peak. Mind you, for that reason there's not really any point in filtering a sub on its own because all you'll do is make it louder or softer; there's no frequency content to change. May as well just use a sidechain compressor on the sub channel.

There are loads of envelope filters out there; ableton has one built in that's sidechainable. Which 3rd party filters you can sidechain off another input, I'm not sure, but there's definitely no technical reason why it wouldn't work.

Im not talking about a sub sinewave, as your right, this would not happen. I wasn't clear but i was talking about bass as a whole and the sub frequencies from it. Basically i think its safe to say that anything with harmonic content this will happen, pure sub, no.

It can happen that playing with phase will make your peak levels somewhat higher, yeah, but it's a special case and you won't get massive peaks. If you're using a non-resonant HPF or LPF (or whatever - anything that doesn't boost a particular frequency) then it's much more likely that the peak level will drop as expected. Either way, it's related to the filter itself, not the fact that the cutoff frequency is sidechained.

A sub is a sine wave

To be pedantic, this isn't necessarily true. The sub frequencies are always sub frequencies but the wave playing these frequencies doesn't necessarily have to be a sine. Obviously they all come back to a fundamental frequency but you'd be absolutely wrong to say that all subs are sine waves.

If you were responding to my question, the point is that I'm not just using a 'sub', I'm using a patch that contains an oscillator dedicated to be a sub, so the aim is to sort of bypass this oscillator whenever the kick plays, but obviously this definitely won't be possible with a sidechain so the aim was to high pass or low cut the sub frequencies whenever the subby kick plays.
