Thanks for the SOS link.  I'll have to work with it after I get it. It will be great if I can get it working as a VST.

It's a great reverb using and I like using it as a hardware insert within Sonar.  No delay whatsoever.  You will enjoy using it.
 
One note, assign both of the processors to the same logarithm for a better reverb sound.  See  ~~> HERE
 
 

Got the unit.  I installed the driver and then MX Edit program.  Connected via USB and Windows detected and installed it.  Its communicating with the MX Edit program.  But, Sonar (and Studio One 3) do not see it.  What else do I need to do????
 
I see an option in the manual of connecting via S/PDIF but that is not USB/VST.
 
EDIT: I found the MX200 VST and added it to the Cakewalk/VST Plugins and Sonar picked it up when it scanned the VST's but I still don't see it.
 
 
 

I see I was using my other log on. 
Anyhow,, I never did get this to work. The reason was the VST was written for XP 32 bit and reports were it never ported over to W7 and above. They just never put any effort into it. So XP 32 only. 
 
I still use this for my Live effects. 
Funny reading this I forgot about trying the TC voice live.. But I ended up buying a TC Voice Live Play acoustic just this fall. Main reason is for my acoustic guitar with the Body Rez feature. I have the Effects shut off. Compared to the MX 200 they sound dull.  
I guess the word I would use for the sound of the MX200 live is "musical" 
Most effects suck the life out of your sound and just muddy the waters. It has a nice shine it put on things. 
I guess I could patch it in as analog in/out. 

That sounds like what is happening, the 32 bit isn't working in Win 10 64 bit.  Looks like I'll just have to use it as an external patched in unit.  

I'm in luck.  The buyer I purchased the used Lexicon from has agreed to take it back.  It really is of no use to me as I bought it to use as a VST, but since it won't work on Win 10 (64 bit OS) I was stuck trying to make it work as an external effect until he agreed to take it back.  Will just cost me the shipping.
 

Sorry to hear that the VST option is limited to 32bits.   You could use it as an external insert within Sonar as I am currently using it, but again it is only being used to add reverb in the singers ears while recording.

My MOTU 896Mk3 Hybrid has reverb capability built in to send to singers, so I didn't need it for that.  Just thought it would be a nice to have Reverb (and Delay) option as I've always like the Lexicon reverbs.  Too bad it didn't work out.
