Keepforest Ferrum Free Edition

Keepforest Ferrum Free Edition is the freeware version of Keepforest’s modern trailer percussion library. The free edition includes 42 sounds from the full Ferrum library: impacts, hits, punches, anvils, and metallic percussion, with a single mic position. Everything is recorded with trailer production in mind, which means the samples are aggressive and pre-processed for impact. There’s also a built-in step sequencer that can modulate filter, pan, and pitch per note, which is pretty useful for building cinematic percussion loops.

The installation process is slightly more complex than most libraries here. You’ll need a Keepforest account, their file manager for the initial download, and Native Access for activation. Not my favorite way to install, but it’s worth the extra steps if you score trailers or cinematic music. 2 or higher.
