Genium's Sylenth Soundset is a commercial, but very reasonable priced soundbank which contains 100 presets for Lennar Digital Sylenth soft synth. The presets included are: 10 Arps, 20 Basses, 1 Chord, 10 Dubstep, 6 FX, 20 Leads, 6 Pads, 10 Plucks, and 17 Synths.
Genre ? Well, if you like Sylenth factory bank which focuses on Electronic Dance Music then Genium's Soundset is a nice extension. There at least few presets I like a lot, ie. LD Hunted, LD Flight, PAD Living on Clouds, PAD Vengeance, PLK King, PLK Distorted ...
Overall, If I was designing this bank, I would add a little bit more modwheel settings to some presets but still, for 5 $ it's a pretty much No-Brainer deal, especially for those who simply like Sylenth, like it's bright sound.
