This blog is exactly what it says on the tin: a blog entirely geared toward producers tweaking away in their bedrooms. There’s plenty of sources for free stuff, but most of them are hit-or-miss in terms of quality. You’re not likely to find any buggy, poorly designed, or otherwise useless freeware at BPB. Everything they’ve ever led me to has been extremely use-able and a lot of my current go-to synths, effects, and samplesets are finds from BPB. Be sure to check out their ‘best of’ lists.
