Multi-Band processing with more than 3 bands?

Hey guys, one thing i really like about ableton is using multiband compressor to control different bands of a sound to make cool effects; however i wish it had the option of adding bands. since it doesnt; is there any way i could split a sound into 4 or 5 different bands, without overlapping or removing any frequencies? Thanks

Rack an EQ 8, duplicate as many times as you want bands,make the first one a low pass and the last one a hi pass, band pass in between. It will be tricky to make it nice and transparent, though.

You might find some ready-made 4 band splitters here if I remember correctly https://performodule.wordpress.com/

Racking eq 8s wont give me the effect i want; I dont want any missing or overlapping frequencies and theres no vertical filter modes on the eq 8.

Fab pro mb is exactly what i need, but i was hoping to find a free alternative before i payed money for yet another plugin

Not sure if reaXcomp does this: http://www.reaper.fm/reaplugs/

would using eqs really have the same effect though? There would have to be at least a little overlapping\missing frequencies, the filters just arent steep enough

How accurate are regular multibands? Have you ever muted bands of white noise to see the result on a spectrum?

hmm i havent actually, might try that, can you think of any reasons for why they wouldnt be perfectly accurate though?

there is no such thing as a 'perfect' filter. every filter design is a compromise...

Isn't Live's Multiband compressor exactly that: an EQ with a high-/low- and bandpass filter followed by compressor algos. No magic tech involved.

I know someone (Tarekit I think) made once a EQ8 rack with very transparent crossovers originaly intended for DJing. I'm sure that could be appropriated for Multi Band compression by also placing compressors in each chain.

The handling will not be as comfortable as the Multi Band Compressor or the Fabfilter device though.
But that's the nature of workarounds, isn't it?!

If I understand it correctly, any filter causes some phase distortion. But I am no expert.

actually, linear phase filters avoid phase distortion, but at the cost of pre-ringing (and extra latency)...
