I did a clean install of Windows 10 today on my main machine and after installing Platinum I noticed that the Cakewalk DX AmpSim effect was missing. I have lots of other amp sim stuff, notably Guitar Rig 5, but I love the cheesy little AmpSim gadget. With the right reverb/delay effects it's pretty wicked in the right kind of setting so I was pretty distressed that it wasn't there. I manually installed every single installer in the Command Center downloads folder; alas, it was nowhere to be found. I finally got it working again, along with the Pitch and Tape Sim plugs. I went looking around on the forum to see if anyone else had run into this and couldn't find anything, so I thought I'd post what I did for anyone else that finds themselves in this bind. The old hands probably already know all this.
I went digging around in the old Program Files folder from my previous version of Windows (in Windows.old after the clean install) and there they were in Program Files\Cakewalk\Shared Plugins: TapeSim.AX, AmpSim.AX and Pitch.AX. Clearly these are not VST plugins, they are in fact DirectX COM components, and they get registered with a special utility.
So I fired up a command prompt (running as administrator) and set the working directory to Program Files\Cakewalk\Shared Plugins and ran the following commands:
regsvr32 AmpSim.AX
regsvr32 TapeSim.AX
regsvr32 Pitch.AX
After firing up Sonar, there they were, and I'm very happy they are.
I do have a question, though. Are these plugs no longer shipped with Sonar and the fact that I had them just artifacts of previous installs? I had X1, X2 and X3 installed also, so it's possible. And if they are shipped with Sonar, what installer should I run to get them?
Anyway, the day was saved and I'm a happy camper.
