Scott,
The Studio Manager was obsoleted with the introduction of version 1.6.0 of the Editor quite some time ago.
Just to bring you fully up-to-date: Studio Manager, which acted as a "host application", was designed for a synthesizer/effect processor/digital mixer
network setup, where an entire studio of external gear could be managed quickly and efficiently... That is, bulk dumps of all settings could be managed neatly... Stored and restored without having to do each device separately, the Studio Manager handled all external devices and their stored setups, per Project file.
Today's computer connectivity has taken on a peer-to-peer setup so the Editor has evolved. You probably don't have a network setup or most people don't... You now have just one program to deal with, the Editor itself, no separate host is ever necessary to run it standalone.
With the release of version 1.6.0 (and later) of the Yamaha hardware synth Editors, the Studio Manager host application was obsoleted (it's over a year or more now). The newer versions of the Editor contain both a Standalone and a VST version. One download, that you simply launch as you require. The Standalone version no longer requires a separate host application. Or you can run it as a VST3 plugin within Cubase (that is what is broken, a fix is due shortly).
Cubase Pro 8 has a known issue with the current Yamaha Extension (VST Assistant). The current Editor version 1.6.4 for Windows, 1.6.5 for Mac is fine and runs well, as a Standalone application. What seems to be broken is the software Extension that
instructs Cubase about addressing the Yamaha hardware. Being an external device the computer has no idea of the workings of your external device, the VST Assistant (contained as part of the Extension software) will need to "teach" Cubase how to properly address the external Yamaha hardware. The Editor and the majority of the VSTi routing benefits are still available.
Currently, you can use Automation, Freeze, Export Audio Mixdown, VST routing and processing by setting the keyboard up as an EXTERNAL INSTRUMENT Plugin (please see the link below for step-by-step instructions on how to set this up). You still setup the Yamaha synth as a VSTi, and you'll run the Editor as a Standalone application.
You'll need to save your Editor file separately... That is, it does not get automatically bundled into the Cubase Project File as when you run it inside Cubase. Other than that it works just like you've been used to, except you now can customize the Returns as you require.... (It actually has a distinct advantage to FW users). The
EXTERNAL INSTRUMENT feature is how any external hardware synthesizer can be setup to work with Cubase. The whole concept of VST was to include both internal virtual synths and external hardware synths in the computer-based environment. Yes, this is a key advantage, and is at the core of Steinberg's VST protocol since the beginning. Yamaha spiced it up with advanced integration features between real synth and computer.
The Editor 1.6.x you'll find works just fine,
right now!!! When the Updater comes you can choose to return to running as a VST3 plugin or continue running as an External Instrument plugin as outlined in the Standalone scenario. Both are viable methodologies, as you will see...

You will need to
update your Yamaha hardware EDITOR version to 1.6.x in order to run as a standalone application.
New versions of the Editor Standalone/VST exist for the Motif XS-series, Motif-Rack XS, MOX6/MOX8, S90 XS/S70 XS, Motif XF-series, and the MOXF6/MOXF8.
These do not use the Studio Manager. Products that previously relied on the Studio Manager as "host" will continue to do so. If you wish to use one of the products above with with the old Studio Manager then you must remain with the Editor version 1.4.0 (still can use SM2).
