Q: How do I backup my Audio Presets or Transfer them to another machine ?
Answer: In order to transfer your audio presets from one machine to another, download and install the Sony Preset Manager utility from this page.
When you launch Preset Manager you will see a list of your custom presets on the bottom part of the window. To backup all your presets, drag the FX Plug-Ins folder from the bottom window to the top window (if you only want to backup some FX then expand the FX Plug-Ins at the bottom and drag only the specific ones you want to the top area). Now, go to File > Save As in order to save out a .sfpreset package file.
To restore the plug-ins on a different machine (or the same machine if you had to format your drive), install Preset Manager, then go to File > Open and open the .sfpreset file you previously saved. Then drag the FX Plug-Ins folder from the top window down to the bottom in order to restore those presets onto the system.
