I really love using this for many synth based tracks, while it very difficult to find because of it rarity status.
I still enjoying it as it a great Expansion Card from Roland
The sounds of this expansion boards sound different depending on the module it's installed in. I have two of these cards, one in my JV-1080 and one in my JD-990 and I have to say they sound better in the latter. The presets are amazing, there isn't one that sounds bad.
