This synth has grown on me over time. I liked it very much when i first purchased then i went for about 3 or 4 months without using it. Now i've come back to it, and it is indeed a very nice synth. I don't really use it for bass or for leads; I use it mostly for "incidental" sounds. I love tweaking this thing. The filter is great and all the fx are very good.
The presets are kind of hit and miss in my opinion. The one thing i wish it had was adsr functionality. I seem to fairly regularly wish this when I'm playing with it.
In the end, this synth fulfills it role in my case, and was a very good purchase for the money...
