Surround in multibandconvolution. input in channel L/R (1/2) does not produce reverb on rear channel

[magicmusic]

I use reaper and 64 bit plugin Demo. On right side can see it is set to 7.1 surround. I enable 1 2 3 4 5 6 in channels surround setting and i test 1 2 5 6 too. Same Problem. I use Preset Church (true stereo) 3400ms Prbrt29. there can see in file tab, that there is a front-l ,front-r, rear-l, rear-r file. So it should produce reverb in rear channels too. But i see no info what impulse is map to which channel

Only when i map the input channels 0 1 to your plugin in reaper to channel 2 3 input of multibandconvolution (reaper begin with 0 in this situation) then your plugin output on Center and LFE channel. When i map channels 1 2 to 4 5 then your plugin output at rear channel. When 7.1 mode is enable the level meter does only show in, Side, out with 2 channels. So no level of Center/LFE rear left rear right is see.

And i see no setting or display so i can see that rear-l rear-r impulse is correct use for rear channel. best is when can choose impulse for channels. For mid channel and LFE i need no reverb.

another thing.

I test multibandreverb too and there can see in the presets that there can good a chorus simulate by modulate the width. But in multibandconvolution, i see no feature that a chorus can simulate, that make reverb fuller. The fade between IR 1 and IR2 i test for modulate, but give not such a effect. I see your plugins have lots many features, other not have, so its hard to find the needed feature, so maybe i miss something.

I just checked MMultiBandConvolution in Reaper and everything seems fine. Note, it does NOT show you what IR it selected for each channel. Please check the documentation about topologies. Basically in the default topology and your one 1 stereo IR it maps to like this:
1->L
2->R
3->L
4->R
...

There won't be any complex settings, sorry, it is meant to be easy to use and do everything automatically. Surround processing will just always be complex. Anyway in the docs about topologies you can see info about how to set each channel to specific IR by naming the IR files properly.

As for MMultiBandReverb - that's an algorithmic reverb, which is a very different thing. Convolution reverbs cannot be modulated in many things, because each change need a lot of preprocessing. That's the strong thing about algorithmic reverbs, they can be modulated.

What reaper version you have ?. I have reaper 5(i test with it) and reaper 4, so i can upload a example project, that show that rear speaker play nothing when input is not map to MMultiBandconvolution input 4 and 5. It is no problem if such a mapping is need. But i see in your preset 5400 zkr52 true stereo front/rear that the rear channel is too loud. I see no slider to reduce the level of rear channels or center or LFE. or you do a example project

Here can download free surround impulses.

http://www.openairlib.net/auralizationd ... -cathedral

but there are more files for surround support.

This is a 6 channel wav, but i have split it into 2 wav files, so i can use 2 reaverb 1 for front 1 for back. so i know how this sound good.
I rename the files and MMultiBandconvolution hopefully use them correct. the name of the files i change to stalbans_b_williams_front.wav and stalbans_b_williams_rear.wav Is this correct to detect ?

And this impulse file have more bass on front but less bass on back, and back is more silence. So i can hear clear that when i map input 0/1 to input 4/5 for MMultiBandconvolution, the rear reverb output is same file as front speaker. when i choose the rear file in gui, my rear speaker are too more silent and have no boomy bass.

I notice that Mvibratro before MMultiBandconvolution give a good warm chorus, whith all settings default, and speed 0.5 hz, 30% depth
maybe you can try out how good it sound then, and there can add a limit mvibrato with only speed and depth value, so its onboard, and need not wire to modulate. reverberate simular price, have 3 choosable chorus(1 post all, 1 post IR 1 , 1 Post IR2 )but no surround support. MMultiBandconvolution is also better to choice LP HP damping in time. There are also other convolution reverb, that have a builtin chorus. 1 chorus for over all is enough. i notice when have the chorus before it sound better, even more with longer reverb time

Hmmm, I downloaded the 6 channel wav file, used Reaper 4.78, found no problems really. Please contact me via info@meldaproduction.com, I'll send you the Reaper project for testing (or you can send me yours, will all the necessary resources).

About chorus - sorry, that's not really planned. You can always use MMultiBandChorus or some other plugin before MMultiBandConvolution. After all that's what the plugins are for. Or you can use MXXX (preset action is going on right now http://www.meldaproduction.com/plugins/ ... hp?id=MXXX ).

thanks, now with 9.05 and above all work ok, when choose expand xxxxx to surround. when disable reverb for channels 3(Center) 4 (LFE) then the reverb sound on surround systems even more better and give due to rear speakers more room feeling. 3 good sounding surround impulses are attach. so it is now a full surround reverb and work as other surround reverb too.
