Call me immature, but every time I read the phrase "Cluster Sound" I think: "Cluster F___" and it's not just because of the phonetic similarities. Cluster Sound releases loop-sample pack after loop-sample pack of high-quality DJ fodder, continuously adding to their Tech Producer DSP flagship collection, and they've just announced FOUR NEW "XPander" packs that turn the Tech Producer library into a real Cluster-Eff.

These four new packs are available as a free download for registered owners of Tech Producer DSP and, once added to the existing collection, give those users a 17 GB loop-sample library. The new packs include:

• XP07 – Dynamic Box
• XP08 – Waver Pack
• XP09 – Graincussor
• XP10 – Pulse Blocks

Together, these XPander packs represent 1750 WAV loops and samples, 800 REX2 loops, 1600 Drum Rack sliced loops & devices and 1070 instruments and drumkits for Live, Reason and Kontakt.

If you're not yet a Cluster Sound "Clustomer," as I like to call them, it'll cost you 249.00 € (about $315.00 US) to get access to "The biggest DJ library of the planet (sic)." Spelling aside, Cluster Sound is seriously worth checking out.
