25.04
Improved cathode follower algorithm. This results in a more open and dynamic response for models that use a cathode follower.
Updated Plexi 100W and 1959SLP models. A soft reset of the Amp block is required to load the new default values.
Updated phase inverter parameters for many amp models.
Fixed Per-preset switches with "Preset" functions now correctly trigger Layout Links in all cases: tap/hold, normal/stand-in.
