Old version 1.2.4
Release Notes Vastly improved filters and completely revised on-linear analog filter design!  With this release we have revamped the non-linear analog filter model significantly, providing more character than ever before. In addition, the two analog-modelled filters can now run in parallel and in sequence for more flexibility. In fact, two sources of non-linear filtering action are now provided: 1) Within-filter non-linear processing to simulate saturating analog filters, and 2) Post-filter non-linear post processing to give the filtered output even more grunge.
