I've never reviewed a synth, but this time I want to share my day one impressions of Serum. Because in my view this is a superb instrument. It has the analog sound quality of Diva and can compete with the dance sound of Sylenth, the flexibility, the 'roar' and creative matrix options of Massive, the wavetable sound flexibility of Z3TA2 and then some (like the unique formula-to-wavetabel option of the Max Phase Distortion Synth). Wrapped in a GUI that stimulates exploring all these opportunities. And that's rare. So it starts at a rating of 10 and then you start looking for downsides or shortcomings, which I after two days haven't found. I build a bass-sound like the unique Michael Kastrup Bass Funkay sound in Diva: almost as good. Incredible pads, a draw bar organ second to none, a matrix you can understand, all the effects you'll ever need (although the chorus in Z3TA2 is better) and an LFO that makes you forget there is no arp (and if you need one, just use Cthulhu). Try it. Use it and compare it to your go to synths. See how quickly you make the sounds you want and share your view. I'm convinced you'll be positive.
