Can a GUI get any better than this? I think not! This thing oozes quality all the way. An absolute gem.
Sounds: Big'n'fat are the order of the day here. With a simple twist of a knob, you can turn a mono sound into a big fat stereo sweep. Crank up the filter and get THAT 303 squelchy lead. IT has discreet control for overdrive and numerous (and quite odd) use of envelopes. There are quite a lot of base waveforms to use on the 3 oscs, but I find them too similar. However, it makes up for this in filter types, fx, arpeggiator, etc. The big filter sweeps reminds me a lot of the Korg Prophecy; it had that same huge sound.
GUI: Everything is laid out logically and for quick access, which is always a plus. Just click on an osc window to display a drop-down selection list. Quickly switch FX on and off for auditioning. As I've said earlier, the GUI is sexyness all the way.
Presets: There is quite a bit of diversity here, and there appears to be a bit of crossover to reFX's other synths, which is great in my opinion. This synth is very versatile.
This really is one of a handful of top-notch synths out there, free or otherwise. I place it in the same quality league as Novation's V-Station. Excellent stuff.
I asked today through a reFX support ticket wether it is somehow possible to purchase Vanguard legally. The response:
"Vanguard 2 will be releasing very soon. I don't have an exact ETA on its release though. You'll receive an email once it's released since you're signed up for our newsletter. Shouldn't be much longer."
I even have a screenshot! Just can't attach it here.
