Anyone running a Lexicon MX400 with Sonar and 64-bit?

I sold my MX400 and happily bought software to replace it, like Valhalla Room, Breverb, etc.  In my case, that has worked out better for my workflow since I wanted to be able to use these tools all over the place and not be limited to just a couple inserts etc.  Much more flexible for recording purposes anyway.

Yes, I rescanned the plugins.
I can load the plugins (MX400 Dual Stereo A and B) as well.
But then I get the message from the plugin "No available devices was found".
I read an article that the plugins are very poor and have problems. And I found a post in this forum that someone had the same Problem within Sonar.
I would like to know if the problem is with me or at the Lexicon plugin.

I just found an old SOS article about the Lexicon MX400 which reminded me my I use my MX 200 strictly as an outboard reverb.  The Lexicon MX units do not allow audio to pass through the reverb using USB.   USB is only for controlling the MX edit software on the computer, the reverb unit must still be connected via the audio cables.

I hope this helps,
 
Peace.

I am having a similar problem with my MX300 - but I think it has to do with the warnings that you will get this error message if SONAR (or any DAW) grabs the MIDI port of the MX unit. My MX shows up in the preferences/setup section of SONAR, and its audio and midi are de-selected, but it still cannot load the VST properly. So I assume it is some snafu to do with SONAR and your interface (mine's a Focusrite Scarlett 18i6) and SONAR grabbing up all those resources when it loads.
 
However, we do use Windows. And I can run MX-Edit in its own window, outside of SONAR, and control the MX that way - it still passes audio to and from my interface (and therefore SONAR) via the S/PDIF connections just fine - all the while being edited from MX-Edit outside of SONAR's shell. Yes, being able to bring up the edit window through the VST interface would be AWESOME, but everything on my MX works fine other than that and having an outboard reverb/delay box is awesome. It takes no CPU cycles at all and is super smooth in real time.
 
All I can say to you is to make sure you have all the proper (read: updated) drivers for you MX installed. Mine came with drivers and software for Windows XP - I had to find, download and install different drivers for Win7/64bit. Aside from the VST not properly loading the MX-Edit app (which admittedly installed and reports as a 32bit VST), it should otherwise work just fine.

Here is a link to documentation from Lexicon for this device:

In it, they quite clearly indicate that it is 32-bit only, so whatever it loads will get the BitBridge (or JBridge if you own that) treatment.  Many 32-bit plugins do not seem to play well in 64-bit Sonar, but it varies widely as to which ones do or do not.
 
If you have a 32-bit Sonar installed, you could try launching THAT, and then see if the Lexicon loads up properly there, as it would all be native 32-bit.
 
As far as seeing it in Sonar, you would have to make sure the path to it is in your search path for VST plugins.  You might also have to check the box for the setting in Preferences that tells Sonar to Open All Devices (or whatever the exact wording is).
 
The 'Always Open All Devices' setting is actually in: Preferences>Audio>Playback and Recording.
 
I hope any of the above helps,
