I ran the Vienna Suite demo all OK, everything was very much stereo.  Selecting Mono input probably wouldn't make a lot of difference, it seems to be the stereo output you are having problems with.  I use Cubase, so cannot help you with Pro Tools, but the problem is not the Vienna Suite demo mode, must be something in Pro Tools upsetting the Vienna IR's

Hi all. Is this a bug or limitation of trial software? I was trying to use the latest demo of Vienna Suite Convolution Reverb in pro tools 8 m-powered (latest software update). The reverb (using 4 channel factory presets) sounds "small" and seems to be only mono. Pressing the button "MONO INPUT" in the user interface doesn`t change the result. It sounds the same. Using other free IRs (2 channel .wav) results wide stereo reverb. Could this be an error of using it? Or is it a bug or limitation of the demo license? Thank you very much for responding.

Welcome Mniedack!

A few questions: Assuming you used an AUX-channel for the VS Convolution Reverb - did you mute the "Dry" signal? Are you using a stereo AUX channel for the Reverb? Is it routed to a stereo bus or output?

Kind regards,

Hello Dietz,

I am using the reverb in a stereo aux track.

Aux Track Input: Bus 3-4, Output: Interface Output 1-2 (Master)

Fader "Dry" show "-inf", Fader "Wet" show "0,0db". The sound doesn´t change while muting the dry-signal.

The original signal is a recorded sound from a classical orchestra in a concert hall. It is wide and transparent but rather dry. Adding the reverb, the sound becomes less stereo. It sounds to be more centered. It sounds as if a mono reverb is added to the original stereo signal.

Kind regards,

Seen from the distance, you do everything right.

I use VS Convolution Reverb quite a lot in ProTools, although in its HD-version, so there is a slight chance that there is something wrong with the plugin in LE, but I don't think so.

Would you mind to post two small audio snippets of both the dry  and the "wrong" wet signal? And please tell us which preset you used.

TIA,

Hi Matthias,

thanks for posting the files.

I'm sorry to say that there must something else going wrong, because here the rendered VS-reverb sounds perfectly stereo. The main difference in comparison  to the other reverb-rendering is the fact that it is a few dBs lower in volume (.... and of course it sounds better ;-D ...).

Please take a look at the screenshot below:

[URL=http://img46.imageshack.us/i/vsrevtest.jpg/][IMG]http://img46.imageshack.us/img46/3708/vsrevtest.jpg[/IMG][/URL]

... what you see is your VS Convolution Reverb rendering brought up by several dB, playing in solo mode. The Goniometer image of the signal displays a circle, the Correlation meter below it a value around +/- 0 ... two indicators that the signal is almost perfect stereo (more or less 100% decorrelation between the left and the right side).

All I can do is to ask you to re-check the routing, please.

HTH,

Hello Matthias,

The thought seems to be logical - but why would then the ProTools-rendered reverb file be full stereo ...? Apart from that: As I told you before, I used VS Convolution Reverb for literally hundreds of productions since we released it, both in VST format (Nuendo or Cubase / PC) and RTAS (ProTools HD / OSX), and I can't remember a similar problem.

I will ask our developers to look into it nonetheless.

Kind regards,

The audio in www.n-medien.de/zip/reverb-test.zip sounds perfectly stereo, so it seems you may have some routing issue outside VS Converb.

BTW: Matthias, would you mind to post your seemingly mono-ized ProTools-"mix", too? Up to now, I don't have the slightest idea what you're actually hearing! :-)
