Please make sure to use the correct term - whether you need/want encoding or decoding.

Recording the decoded signal (via loopback) is quite unusual, as the main advantage of MS recording is lost (post processing of stereo width and ambience).

If the decoded signal is strictly mono then either the microphones have the wrong directivity, are placed wrongly, or have wrongly soldered cables (phase inversion). Your screenshot shows that TM works exactly as intended, and you can easily check that by using other signals, like stereo CD.

Hey again!

Matthias suggested to check that "TM works exactly as intended", by using other signals than a M/S microphone pair, "like stereo CD".
Well, today I did some test / experiment following this idea. Let`s see what happened. :-]

Let`s face the User Manual, which says:

"The M/S-Processing automatically operates as M/S encoder or decoder, depending on the
source signal format. When processing a usual stereo signal, all monaural information will be
shifted into the left channel, all stereo information into the right channel. Thus the stereo signal
is M/S encoded."

It means:
If you put in a M/S microphone pair, M/S-Processing gives you L/R Stereo.
If you put in L/R Stereo, M/S-Processing gives you M/S pair.

First, I take a cut from a CD (copyrights by EBTG . My aim was to pass it through M/S-Processing in TotalMix and record it via Loopback. The routing look like that:

I was awaiting to get a neat M/S pair, where all the middle information is on left and side stuff is on the right side.
What I got insted is a sound where everything is just summed to mono (I got it in my headphones as well).

Here is link to the initial CD cut:

Original CD sound

and here is re-recorded CD cut with M/S-Processing on:

M/S processed CD sound

Next attempt was to try the opposite: to put in a M/S microphone set and to get out the desired L/R Stereo sound - both in file and in my headphones. To complete that, I was going to record the M/S-Processed file (via Loopback) and unprocessed ("rave") microphone pair as well. I recorded those 2 files synchrone, as you can see in this setup:

Well, the results was not as those promised by Manual, but just as I expected from previous experience with CD:

with M/S-Processing On, the resulting file was monophonic, everything summed:

M/S mics with M/S Processing On

without M/S-Processing the sound file was just as the microphone setup: middle mic on the Left channel, side mic on the Right:

M/S mics with M/S Processing Off

Thats all! But - how come?
I would be happy about any idea how to make it work.
Maybe it is just my fault. Matthias - where is the fault?
Maybe it is a fault in driver. Matthias - is it in the driver? I`m using the last one.

hope remains! ;]

thanks

Hallo Matthias,

1) yes it seems that I can use panorama as intended.
2) Here comes the screenshot of driver Settings:

3) I update driver time after time and I rebooted my Multiface 1 - recently it is connected to PC via USB, so there is no external power supply.

What should I do?
Hope to hear from you soon.

best regards

Girts

Hey S-EH

Yes, in this concrete case that`s correct: M/S Processing on to:

Ph L & Ph R to (monitor M/S via headphones)
and
An 43 & An4 (to be able to record the desired M/S-processed sound).

And - yes I tried to explore M/S-Processing by sending in stereo sound instead of M/S pair. I described it a bit earlier here.
For me, it seems that the Phase Inversion (represented by that blue rectangle in Matrix) just don`t work and that`s the reason why it all goes just Mono when M/S Processing is "On".

Girts

As you can see in the above screenshots the side channel is panned center, but phase inverted on the right. In other words 0? to left and 180? to right.

I am very sorry (and embarassed as well). We just have too many products, so even I get confused sometimes.

The Multiface does not support phase inversion. In fact it does not say that it does anywhere. If you press shift and click on any level in the Matrix the field will not turn blue.

The display of this function in the menu is a simple error, as TM supports numerous cards. It must be removed for the Multiface (which will be done in the next update).

Sorry again.

MS processing works fine with those products that support it (sorry I also didn't think of the fact that the MF doesn't...). So I'm not quite sure what the point is here...

Since we do not claim that it works (e.g. in the manual), there is no bug here...

Quite possible.

You could do so with your audio software. If it's possible in playback,it might also work with software monitoring. I know Samplitude could do it.

I don't know which manual you've been reading, but the neither the current manual for the MF II nor the old one for the MF I mention M/S.
Please tell me the file and page you are referring to.

Then we'd also have to mention that the unit does not support DSD format, will not encode oder decode AC3, and can not be used as a video recorder or microwave oven... fryingpan
