Valhalla has released a free reverb plugin called Supermassive. Famous for their high quality reverbs, the new Valhalla plug is designed specifically for extra-long reverb and delays and features eight different sound modes for different reverb styles. 

Valhalla says that combining “these long delays with the unique WARP control, and the results range from echoes that slowly fade in, to cascading harmonic echoes, to lush reverbs, onwards to reverbs that decay way over the course of minutes.” A density control lets you determine the tone of the space created by the reverb and delays. 

Supermassive is a free download and is available now for macOS and PC. Read our list of free music-making tools here.
