After only 3 hours of use I'm very troubled by this VST.
Using the latest versions of FLstudio on 64-bit Windows 7, it doesn't seem to matter if I'm running my DAW in 32 or 64-bit, bridging the process (which normally lets me bypass DAW crashes from VSTi completely), threaded processing turned off or not, there's some peculiar problems that occur. On almost regular intervals it crashes my DAW when I open or close the VST. Sometimes when I open the menu to view the presets, sometimes when I try to change values on the effects. The rate it crashes my software is quite frankly alarming and I would never consider using this for production. If I could find a work-around for it I'd do that and be sure to post it here but even my counter measures I take for troubleshooting that worked for literally everything else in my entire lifetime of working with digital music software seems to have had no effect whatsoever. I'm at a loss.
Aside from that, other things I've found common are that when I load in a preset, all drop down menu boxes are blank until I select a new value. With the Mod Matrix and the Effects Stack I can't see where the currently loaded effects are, if I try to add one I might accidentally replace an effect.
And when the visual display freezes, it works as a pretty good indicator I should save my progress soon as a crash is coming up soon.
The presets are nice, a lot of the sounds are fairly decent, I personally love the Acid presets as they sound pretty legit. Some of the Pad presets are also nice and thick. In the current version of this VST my best advice is to not load it up directly into a large project so you don't have to risk loading it when opening your project later. If you decide you want to use this VST at all, take a MIDI file or sequence from your project into a new project with only this VST in it, and bounce down the audio into sample format.
When I saw this VST it really got my hopes up to test and review it, but it just didn't work out for me. If you have a positive experience with this VST I highly encourage you to write a good review for it.
