Well, I don't often write reviews of products, but this one I just had to...
For just $29, this has to be one of the great VSTi bargains out there. A superbly warm synth that can generate gorgeous pads, cutting lead sounds and punchy basses. And to go with this, one of the clearest interfaces out there.
I'm normally a bit of a no hoper when it comes to programming synth patches, but even I've been able to come up with some great sounds with this baby. Just find an existing patch you like (there are plenty supplied with the synth), keep pressing the "GEN" (randomisation) button until you get a sound you like and then manually tweak it to perfection.
Stability is also good. I'm running Alpha in Sonar 2.0 with the fxpansion VST-DX adapter and I haven't had any problems whatsoever.
And to add yet another thing - you also get some of the best support out there. I had a little problem when I ordered Alpha, so I emailed Peter and he had it fixed within half-an-hour. He's also brilliant at answering questions left for him on his support forum, right here at KvR.
Due to the clear interface and ease of programming, I can wholeheartedly recommend this to anyone from the experienced artist (who'll love its low CPU usage) right down to the absolute beginner (who'll have their own bank of sounds within an hour of purchasing). Add to this full MIDI-learn capability and the incredible modulation matrix (hey, I paid £600-odd quid for a Proteus 2000 with one of those!) and you have a synth that will be one of the mainstays in your VSTi armoury.
So, you might say I'm pretty happy with Alpha - I can see me using it in just about all my projects in the future. And besides, $29 is nothing really, is it? Go on, you know you want to :)
