I have the Sonic Cell not the SD 50......problem right now is there is no Windows 10 driver for it. I had to go to the Roland Clan to find a work around so it will use the Windows 8 driver. One of the things that irritates me the most is it wouldn't take that much for Roland to mod the install package of the Windows 8 driver since it works but because they discontinued it they don't care. Okay off the soap box. I remember the sounds on it being like the Fantom sounds and were pretty good. The sounds on SampleTank are pretty good but some of the violin sounds don't sound that great to me. I figured since I had the Sonic Cell I would give it a go. My main reason for asking is to see if anyone was using one with BIAB and is it worth it to try. I just know I am setting myself up for a couple of hours of futzing around to make it work.
