I misread your post and totally igonored the fact that you're looking for an fxp file. Why would you need an fxp file? Just place the vsynpreset file inside Documents/VSL/Vienna Synchron Pianos/Presets.

In the zip files ATTACHMENTS OF ALMOST EVERY POST IN THIS THREAD.

Here you go. For Yamaha CFX.

All of them are pretty much (like you said) scattered around the respective threads related to both pianos. 

Would be nice to have a user preset thread for the Synchron pianos. I have a couple to share.

Count me in as a fan of the FX presets. Good job Paul and the team. I would love to see more FX presets/soundsources added in the future with updates. Is that possible or the updates consist only on GUI features and improvements ?

Thanks Paul.
