I did a search for this expansion board in our forum and didn't get a match. It's the Virtual Acoustic Plug-in Board. Are any of you using it with your 9000 Pro? How do you like it? I thought the sampled guitars sounded very authentic. But then again I only listened to Yamaha's propaganda mp3 at http://www.yamaha.com/menuitems/audioclip/accessories/PLG150VL/audio/VL_Demo.mp3
