Topic: For M-S affeciandos

The vector scope is a great tool, and would have been useful a few months ago when - in its absence - the M and S channels were transposed in a live mix.   Unfamiliar equipment and environment not under my full control was the reason (not excuse) ...

The Vectorscope/goniometer is a great tool to directly check correct operation - and orientation - of a stereo mic pair. However it is not easy to interpret the display if the input pair is in M-S format.   If the display had the ability to add a sum and difference matrix between the input selection and display, this would be a very useful feature for M-S users.   (Admittedly, a small but hopefully influential group in the RME community?)

An idea from personal experience.  As they said in Madison Avenue 50 years ago "let's run it up the flagpole and see who salutes!"

Hello,

this would be a big step up, for an allready great tool.

Brilliant idea!

Re: For M-S affeciandos

I am sorry, but I dont see your problem.  MS display is just rotated by 45 degrees anticlockwise.

An MS matrix has the property of rotating by 45 degrees.

Re: For M-S affeciandos

We are all aware that in the goniometer using M-S shifts the 'centre' axis by - 45 degrees, but:

1. Current mounting arrangements do not permit me to turn my monitor 45 degrees clockwise;
2. Consistency is a wonderful virtue;
3. Some peoples' visual perception that centre is vertical is rather in-grained with age;
4. I'm well and truly over the stoic thing;
5. In a live broadcast situation, I prefer things to be simpler rather than complex.

I admire your adaptability, and if however, you prefer to preserve the current situation, then you are not obligated to engage the matrix (if it is implemented).

Re: For M-S affeciandos

You don't need to discuss this anymore, it is already implemented in the next DC Windows release (coming up in a few days). Works perfectly.

Re: For M-S affeciandos

Thanks for the speedy implementation.

Only one minor comment - I think it would be useful to have some sort of 'flag' in the display that the M-S mode is active.   While it is fine for my personal use, the use of Digicheck in our multi-user DAW at the Recital Centre means that a previous user may unintentionally leave the Vector Audio Scope in M-S mode, and the following user may be confused by the unexpected correlation and vectors.

I realise that display changes may take more effort to implement, but it would be good to avoid any confusion that may arise where a display that appears exactly the same is capable of operating operating in two different modes.

Gruss

Re: For M-S affeciandos

It's german "sz" or "sharp s" by the way, not ss, even when it kind of replaces a double s. wink

Re: For M-S affeciandos

Thank you for your kind guidance.   Must spend some more time there soon to further improve my skills (the next AES in Berlin would be good).

Re: For M-S affeciandos

... and to the original subject!

Used the M-S vectorscope operationally tonight for the first time.  A great asset to checking correct operation of the M-S main pair I was using.  Indispensable!
