Need some help here. I just upgraded from X1 Studio to X3 Producer. I downloaded Melodyn, but I can not access it. I am no longer seeing the Rewire option available. (it is greyed out). I am running 64bit version of X3. I deleted and re downloaded Melodyn a couple of times. Both selecting 32 and 64 bit options and then 32 and 64 options separately. I'm glad that I still have V-Vocal, but I would like to use Melodyne. Any help would be appreciated. If I posted in the wrong forum, sorry. Thanks 

Melodyne has been integrated with ARA into X3. Now you need only select the area you wish to work with and create a "Region FX" with Melodyne (Select an area, right click ->Region FX->Melodyne->Create Region FX). IIRC, I saw a post to this effect long ago, and think I remember that "Re-wire" is now replaced by this (but cannot recall the exact details offhand).
 
Edit: I believe the Melodyne installer also allows you to install the Re-Wire version, which is part of the Melodyne installer (there are options for 64-bit, 32-bit, Re-wire, etc.). I just checked X3 and I do, in fact, have the Re-wire installed, but never used it.

Or select an audio clip (or part of one) and do CTRL+M.

Thanks, I'm going to check this out as soon as I get to my gear. I chose the option for re-wire install when I downloaded it, but I'm not seeing Re-wire option available in X3 on any project. It's like it doesn't exist. I downloaded Melodyne from their site and then I had to run the set up. When I select the region FX option at the top of the clip, I only see Vvocal available. However I have not tried this option__ (Select an area, right click ->Region FX->Melodyne->Create Region FX).

Hmmm, that is sounding a lot like SONAR is not scanning the VST folder Melodyne installed to. By default, Melodyne installs to "C:\Program Files\Common Files\VST3" check your VST scan paths (Preferences->File->VST Settings) and make sure that one is listed. Also do a manual rescan of the VSTs while on that page (you can also check the rescan failed and existing VST options there for that manual scan).

Thank you mettelus - this solved my problem too!

This is what Sonar advised me to do. I did all that. The path is C:\Program Files\Common Files\VST3\Melodyne. (I believe) They also told me to check that the .dll file was in this location. It is, but the file is Ssetup.dll. The file in my VST3 is Ssetup.dll but the file in my VST2 folder is just Melodyne.dll. I am perplexed. I am pretty computer literate, but not an expert. I assumed that with the upgrade to X3 Producer all this would have been done. 
 

I am not seeing the .dll file in the VST3 folder. It is in the VST3 folder. This is the location where it is C:\Program Files\Common Files\VST2\Celemony\Melodyne. I added scan path to the VST2  and VST3 folder, but Melodyne still does not come up under region effects. Only V vocal appears. I'm at a loss here.

There should not be a dll in the VST3 folder. VST3 plug-ins have a VST3 extension. The default location for the VST3 Melodyne plug-in is "C:\Program Files\Common Files\VST3\Celemony\Melodyne".  The Region FX menu requires the VST3 version of the plug-in. I have not used the demo version of Melodyne or X3 but there was no special configuration necessary (other than registration) to get Melodyne Essential or Editor to work in X3. It appears as a VST3 plug-in, as a Region FX and a Rewire device in the synth rack.

When I select insert re-wire device, that selection is greyed out...when I choose region FX I am not seeing the Melodyne option. Melodyne is in the following location C\program files\common files\vst2\celemony\melodyne and I have created a scan path to this location as well. I am at a friggin' loss. I am going to have to contact cakewalk support. One thing I find odd...I am seeing Melodyne singletrack.exe and MelodyneReWireDevice.dll as well as the Registration and Activation files in another location...C:\Program Files\Celemony\Melodyne singletrack. Not in the common files folder.
