I bought this last night, and am loving it. I can't believe how good it is, regardless of the price. It might not have all of the bells and whistles of other programs, but for my needs, it's perfect. The legato is spot on, and I LOVE that it has independent vibrato control.
If I had any "complaints" (and really? it's $29, I can't complain) it'd be that the 'clicking' seems very pronounced. Not sure if I can adjust that, haven't had enough time to dig into it. Also, it makes sense for the mod wheel to control the vibrato, but that 's going to take some time getting used to, as I keep reaching for it to control expression.
But overall, I'm extremely happy. Embertone were smart to sell this so cheap, as it's a great introduction to the company, and like many have stated here, it's given me the confidence to purchase their more expensive products (in my case Herring clarinet, and John Bell violin) come Black Friday.
