Using MXXX as multiband for any audio

Greeting,
I want to use MXXX as multiband processor for any audio.
So passing the audio through it then extracting the audio via MXXX output(s) to different DAW audio channels to process each one via VST?
To be more technical,
1- I would like to send the audio to MXXX’s 6 inputs
2- then split the audio into the MXXX’s 6 bands.
3- passing the 6 audio bands audio signal through MXXX without using any of it’s interior device(s) or processor(s) just plain signal.
4- then sending the audio on each band to MXXX’s 6 outputs.
5- sending each output(s) to 6 different audio channels of the DAW to process each one with a VST of my choice.
So briefly:
audio < MXXX 6 inputs < 6 bands < MXXX 6 outputs < DAW 6 audio channels.
Thanks,

...why? I don't follow the flow logic. It seems like just a "straight wire" pass though...just curious if I missed something.../s~

You dont need MXXX to do this, just slap an appropriate filter on each audio channel being fed by the originating audio channel

Actually no problem, that's what I thought:

Channel 1-2 works, but on channel 3 has glitches, on channel 4 is only output on the left channel with glitches, on channel 5 and 6 is no output.

Part 1: Dry version
Part 2: All Outputs/Bands together
Part 3: Band 1
Part 4: Band 2
Part 5: Band 3
Part 6: Band 4
Part 7: Band 5
Part 8: Band 6
Part 9: All Outputs/Bands together
Seems to be a problem in MXXX6out, in reaper the channel assignment works.

Ummm, MXXX does not have 6 inputs. Only the main stereo pair and a sidechain pair.

You could switch to Surround mode which would give you 8 channels but, I think, each pair of channels would be processed through the same (multiband) modules. NB That crashes various DAW hosts here.

horizon7,
the 6 columns in the modular editor grid don't imply 6 inputs. There's really only two inputs, each stereo. One is your normal track input, the other for a sidechain. I think what you want is the usual track stereo input being split into 6 bands, then each band being sent to it's own output, which should work.
All bands can use input 1, but each band can be routed through it's own column to it's own output.
Band 1 goes to column 1/ output 1 by default.
For Band 2 put a mixer module in the 2nd column and set it's input to input 1.
For Band 2 put a mixer module in the 3rd column and set it's input to input 1.
And so on...
Trouble is that (as Faiky points out) there are bugs at present, and the whole thing is only half working.
And in REAPER, the 'build multichannel routing for output of selected FX' is not working properly for VST3, (OK for VST2).
Also, generally, MXXX6out is crashing REAPER (at least) just by clicking various buttons.
But when all this gets fixed, I'm pretty sure your general idea will be fine.

That's what i thought, because "audio > 6x Input" and the Audio is mybe a stereo signal, otherwise it makes no sense to send different tracks to a different band. Maybe yes, but I don't think so for his application. The description is somewhat confusing and ambiguous. How many channels does "audio" have?goldglob wrote: Wed Nov 11, 2020 10:47 am I think what you want is the usual track stereo input being split into 6 bands, then each band being sent to it's own output, which should work.

You can do that with other MB plugins, but you'd have to copy them and keep the same settings and other hacks, here it is quite straightforward

I should avoid this anyway.DarkStar wrote: Tue Nov 10, 2020 9:58 pm Ummm, MXXX does not have 6 inputs. Only the main stereo pair and a sidechain pair.

Anyway You mention:

And so on..."
Kindly could you illustrate this if possible?

Vojtech I hope MXXX could have extra inputs outputs in near future, it's really handy since it is a modular FX. anyway thanks for your support.MeldaProduction wrote: Wed Nov 11, 2020 5:09 pmYes, that should workhorizon7 wrote: Mon Nov 09, 2020 8:44 pm Greeting,

If you refer to Faiky's picture above you can get the idea.
See how for band 4 he has a module in the 4th column going to output 4. (You could call the column a 'lane' or 'chain')
And by right clicking the module you can select input 1 as its input.
He is using the PanVol module, but any module that doesn't actually apply an FX will do.
Do the same sort of thing for each band.
