ASynth

Up until I found ASynth, I was using MiniMogue as my source of moog sounds. Well, this thing has better (cleaner, bitier) filters and I prefer it's interface. It has 3 filter models (based on three different synths), and they do sound different. All the usual moog sounds are here; they just sound really nice, especially when linked with delay. My only gripe is that the filter envelope doesn't seem to be able to handle full sweeps from a fully closed to a fully open state :( No matter what you do, you can always open the filter up more manually, which is a bit sucky, as the filter is so very nice on this one.
The GUI is clean, if a bit simple, but it does allow you to quickly do what you want in an unobtrusive manner. Like others, I find the filter button a bit hard to determine what option is selected, but other than that there are no other UI issues. It has portamento mode, which is great for those classic note slides, and a good bottom end.
Overall, one of the best free vsts out there, IMO the best free moog softsynth. Lovely.Read Review
