It could just be creating multiple convolutions and presenting a mix of
those. I am quite sure that they ain't saying
There's a lot more than convolution going on, because that can only model
the LTI characteristics. There are a wide variety of DSP blocks that they
use, including compressors, limiters, distortion generators, clippers,
gates, and of course, convolvers. They're modeling both linear and
non-linear characteristics.
