are processes in normal resolution whereas UltraRes IRs are processed using the
UltraRes engine.
Four of the factory cabinet IRs have been replaced with newly acquired
UltraResTM IRs. These are factory cabs 69-72 (Kalthallen V30 cabs). These IRs
are available on the internet from Kalthallen’s website. For reference the four
cab filenames are:
028c-SM7-V30-4x12.wav"
029c-SM7-V30-4x12.wav"
030c-SM7-V30-4x12.wav"

Improved “Pedal Comp 2” compressor algorithm.
Fixed several errors in the Mr Z MZ-38 model.

Improved Amp block output transformer modeling. New algorithm more accurately
simulates effects of inter-winding capacitance and the resulting load on the
virtual power tubes. This results in improved high frequency response. Tones
have more “chime” without being harsh. This is especially noticeable for amps
with low negative feedback or when the Presence is turned up high.
Added Slope parameter to SPKR page in Amp block. This parameter allows fine
adjustment of the high-frequency impedance of the virtual voice coil (which
affects the slope of the impedance curve). A speaker voice coil is “semiinductive” due to eddy current losses in the motor. This presents an impedance
to the power amp that isn’t fully inductive nor fully resistive. The amount of
resistive loss varies by brand and type. Reducing the Slope simulates a speaker
that is less inductive, increasing Slope simulates a speaker that is more
inductive. Typical speakers range from 3.0 to 4.5 with the median being about
3.7. Lower values yield greater midrange while higher values are more scooped
and sizzly.
Improved Compressor block by adding a new dynamics processing algorithm. The
block has been renamed Comp/Dynmc in light of this. There are now four types of
dynamics algorithms: Studio Compressor, Pedal Compressor 1, Pedal Compressor 2,
and Dynamics. The Dynamics algorithm allows compression or expansion with a
single control. When the Dynamics parameter is set to negative values the block
compresses the signal, when set to positive values the block expands the signal.
Added “Fast RMS” Detector type to Studio Comp type in Compressor block. This
detector type mimics the fast detectors in classic rack-mount compressors.
Added “Dynamics” control to amp block. This parameter controls
processor that can be used to alter the dynamic response of the
When set below zero the amp compresses resulting in a smoother,
sound. When set greater than zero the amp expands resulting in
crunchier and more dynamic sound. Note that extreme values can
