Marina Trench (Z-DSP card)

Mariana Trench turns the Z-DSP module into a feedback delay network.  FDN can mimic the recursive process of sound waves bouncing back and forth in an acoustic space. In other words It can be used to simulate reverberation spaces and to generate very dense echoes. FDN can also be used as a special case of digital waveguides, they can be tuned, or also used as complex delays.
