The FB01 was terrible. I bet the card wasn't much better. Probably even worse.
Sure at the price point. There wasn't anything else that cheap when the FB-01 came out. In a FX synth anyway. I remember playing with it at Guitar Center when it came out.
I don't think I have heard anyone call it good. It was just a lot cheaper then anything else. Its like a hardware crippled DX7. The form factor was totally annoying too. It is totally thin and cheesy sounding. If you like the preset horns on the DX7 then you may like it otherwise phhht...
