I wrote this initially for another forum. But here it is anyway. Hopefully somebody here is interested in multiband distortion. So lets go!
Multiband Distortion and you:
Different frequency ranges of sounds deal better with distortion. Distorting a sub-bass doesn't give you a very pleasing result, distorting frequencies between 200-600hz tends to give you a very muddy sound. Distorting the sound as a whole isn't often the best course of action.
This is where multiband distortion comes in, because you're effectively splitting the sound up into this different "bands" of frequencies, allowing you to distort them independently from each other. This will give you that huge highly distorted sound that everyone is after without
all of the muddiness that can sometimes come with that.
My particular technique revolves around splitting a synth sound into 4 different bands, collating them back into one bus again and filtering them. So basically, grab the synth sound that you want to be distorting.
On the channel that you have the synthesizer on. Set up 4 different send channels (ensure that they are all sending, and one of the send is not muting the others).
Send these to four different send tracks. Name these "Low, low mid, mid and high".
also set up a fifth send track called "Filter".
On these 4 bands do this.
Send 1: Eq'd so it's only got low frequencies(0-200hz), mild distortion. Kept in mono.
Send 2: Eq'd for low mid (200-650hz) A little bit more distortion. Still mono.
Send 3: Eq'd for High mid(800-5000hz) RAMP UP THE DISTORTION, you can start adding fun stuff here too like modulation effects, vowel filters. phasers etc.
Send 4: Eq'd for High only (5000 up) Huge amounts of distortion, stereo widener, reverb, sometimes a bit of chorus effects etc.
then put a send on those four tracks to run into the fifth send, the filter.
On the filter track place one or two filters and a limiter (to keep the volume from being too extreme).
Here's a screen cap of my DAW showing the send tracks and the EQ settings I used for each channel.
(image far, FAR too big to be embedded).
Synth > 4 send tracks > 1 send track with filter.
What's really great about this as well is that the four send tracks not becoming Fixed Eq's. need a little bit more bass in your sound? just turn up the low fader.
Now for what it sounds like.
here's the synth sound before Multiband distortion. (typical comb filtered reese).
And here's the sound afterwards
