ok so iv been frequency splitting with the multipressor but i've noticed a problem. i have it setup as follows lows solo'd from 0-310hz, mids solo'd from 310-3100hz, highs solo'd from 3100-20000hz. problem is when i mute say the high band, the analyzer is showing that the highs are playing frequencies all the way down to 300hz or so, there not very loud, but there there none the less. can anyone chime in on what might be going wrong and a possible fix?

for now i've just got a multipressor on each freq split channel and then an eq after it picking up the leftovers that are still coming through.

Hmm, doesn't happen with me with Ableton EQ3, although the problem I found is some phasing when I change the crossover frequency. Maybe you should try a different plugin.

Do you have high and low passes in ?

no I'm just using the multipressor and i just have the solo button clicked for each separate band. i just followed a tutorial a few weeks ago, but then today i noticed it sounded like some of the blocked frequencies were present, so i pulled up an analyzer and sure as shit...

Been using this same technique with the same problem. Wish I could help but also in search of a solution/method around this!! Also was wonderinga Do most of you guys use a multipressor to split or what are some other methods used? Hopefully we can figure this out OP

yeah i agree. thanks for the bump. hopefully we can find a solution to this issue. like i said for now im just touching up with an eq after the multipressor, but that solution is not ideal.

but hey i just got an idea. i have kombinat, multiband distortion and it has the option to mute each band. i suppose i could use that as a frequency splitter ill try it tomorrow.

err, afaik almost any frequency band is not a -∞ slope. There are overlapping frequencies, and they diminish in volume by X dB / octave. usually 12 or 24, i don't know about multipressor, but sometimes steeper curves are applied. Still, it is very unlikely that it is -∞ dB /octave.
i could be wrong, maybe you set it up that way and it isn't working. like i said i don't know that plug. But more importantly, a total absolute split in freq. bands is pretty much never useful. sound likes to blend, at least to some degree.

well, good luck anyways.

True, I'm pretty sure it's not. Anyways, it's good to have leeway on either side of the frequency band, it's going to sound more musical overall.

i realize that, but my high frequencies shouldnt have sounds from 300hz coming through, that just doesn't make sense. so i guess just cleaning up with an eq or a filter will do the trick, that will give the sound a tiny bit of overlapping to make it blend properly.

honestly depending on what the fundamental/root of the sound is, and how loud it is being played, there very well could be 300Hz content in a band HP'ed at 3k.
I'm going out on a limb and assuming its a bass sound. So, at -24 dB per octave, its possible there's residual bass signal still alive in that band. you could always stack a second HPF after it, to finish the job. But tbh the fact that you see it in a freq analyzer is next to meaningless. Last i checked, our eyes don't hear .


if their amplitude is very low, those frequencies are going to have no effect on your finalized sound.

nope i hear the low end sound too. like with just the multipressor and the high end solo'd it sounds like a really wimpy bass sounds but i still can hear the bass and mids. and this will effect my sound because i send the highs to a spreader and reverb etc...i dont want low frequencies going to those fx. but like you said ill just stick some eq/filters after it to clean up the split.

although as i stated before i think i might try using my kombinat multiband distortion as a splitter. because that seems to split the bands pretty damn well.

Just out of interest eat bass are you using the latest edition of logic and logics stock multipressor and if so how are you soloing the bands becasue i'm yet to find the solo button on my version.

yeah im using the latest version of logic 9 and the stock multipressor. theres bypass and solo buttons for every band.

sounds just like the waves LinMB (linear multiband).. for this kind of layering i get great results from it

i still don't know what makes linear phase filters better, but it might be because logic's aren't?

logic has a linear phase eq, but probably wouldn't be the same as a dedicated filter.

this is logics multipressor btw. see the solo band options

ooh, yours has expanders on it... now i'm jealous

@Today

With Linear-Phase stuff you get the exact same signal after splitting which is good, but you get tons of latency, which is bad. Non linear-phase color the sound which is bad but may not be a problem since you're going to trash the sound anyway.

Try doing A/B with the original signal with a non-linear-phase splitted one (without effects obviously). You should be looking for changes in the lowend or in the signal's peak.

That isn't the same multi compressor i have in the version of logic i'm using,that is the old version you have there.I'm running 9.1.5.I going to have to check when i get home i have a feeling i'm being mugged off lol

Same thing happens to me man, I'm stumped!

the band's crossovers are just very shallow curves that’s all. sounds like they are at 6db per octave or something similar. Helps smooth out any phasing implications or distortions.

I personally use the waves C4 to split my frequencies as the bands are at a steeper db per octave curve.
