Propellerhead Software and Nucleus SoundLab announced Thursday Pantheon, a new ReFill for Reason. The ReFill offers more than 400 patches for Reason, including, "physically modeled drum kits, dirty filter FM basses, majestic pads and heavily sequenced chord patterns to pristine bell tone layers and futuristic lead arpeggios."
Propellerhead is offering Pantheon at its online store, and the company said that each of the patches included in the package is fully documented, with detailed notes on its design. Each is individually tweakable, as well.
Pantheon is priced at €39 or US$49, and is available today. Nucleus SoundLab has posted a demonstration video at Vimeo.
