Hybrid is a Reverb Impulse library that synthesizes the fascinating life of the real spaces with the soundness of the digital reverb units. Up to ten multiple reverb sources have been spread in the stereo field and mixed together using Tube summing mixers in order to achieve unique textures. The library contains 10 IRs and 15 presets. The IRs are designed for the REmatrix multilayer convolver, whose Player version can be downloaded for free.
