Just downloaded this library tonight and gotta tell you it's the real thing. The bass is beautifully sampled and sounds clean and natural -- and has enough little fret sounds, harmonics, etc. to give it that touch of reality. Alan's done a great job.
I also love the automatic finger variations. I listen back to my doodles and can't hear any evidence of that "keyboard" feel. If I didn't know I'd played it, I'd swear it was the real thing.
Alan, I've gotta congratulate you on a job well done. Sign me up for the next one.
