This is definitely one of those FX that just “works”- the demo presets are great (and the real thing is even better) and you should follow Ugo’s advice and try any effect on any instrument. (Very nice with drums, particularly). Despite the name (and the GUI) it is capable of subtle effects as well as extreme ones (burnished, lustrous, reflective, anodised, annealed?).
Doesn’t seem to use much CPU- I’ve had many instances of it running (along with other things) at once with no stability problems.
In the documentation Ugo mentions a problem with a couple of hosts (including Live) where momentary stutters appear if muting/ soloing- I find this happens with many plugins in Live so it probably isn’t a Metallurgy specific issue. The documentation is helpful rather than just descriptive- plenty of hints on how to experiment. Camel manuals are good like this too, but not many others…
The GUI is very clever, but I think I’d like an alternative “cleaner” one- I’ll get used to it though.
I can’t comment on support as I haven’t needed any (yet) but it is obvious what to do if there is a problem and Ugo answers emails promptly. VFM is obvious- it costs what one would normally donate as a matter of course for something this good.
Metallurgy is the bomb. It makes even jaded musicians/producers sit up and take notice. It combines grind with grit with very cool delay and wraps it all in a package that has one of the spikiest gui's I've seen this year. It's easy to edit too - and be ready to save presets that you pass by on the way to your destination.
I've used it on everything I've done in the past three weeks and have yet to find a track that it can't spice up in some large or small way. I've even gone back to past tracks just for the purpose of seeing what Metallurgy can do for them.
The real beauty of it is that it can be truly vicious or nice and subtle. It's great when used full force on drums, but can give a bass line that little extra something when used gently through an effect send - like a pastel watercolor wash.
The $20 asking price is a steal. I would pay 5 times that for an effect of this quality. With the synths that Ugo has given us for free (Motion and String Theory are two that get constant use around here) you'd be foolish not to spend a double sawbuck on this.
I'd like to give it a 20 score in the categories 'Features', 'Presets' and 'Value for Money' but I'm not allowed. That's a shame really because this is the first plugin I've felt strongly enough about to actually take time out to review.
