Modulator
Selects the modulation source for the lter, which may be the MIDI controller selected in the
Modulator CC drop-down menu, velocity, or a combinatio n of the two.
Modulator CC
Any MIDI continuou s controller ca n be selected to control the DEF. F irst select the ‘ CC’
checkbox in the Modu lator section th en select your d esired controlle r from the drop-
down menu located o n the right-hand s ide of the dialo g box.
Velocity (Spectral Int erpolate Velocity)
Setting the modulator to velocity is also referred to as “Spectral Interpolate Velocity” or
"SIV" mode. In this mode, the curv e of the DEF lter is controll ed by note-on velo city,
creating a continuously variable v elocity response. SIV mode can dramatically increase
the dynamic range of a sample set o r instrument, greatly im proving, and in some cases
eliminating, the typical “stair-ste p” sound of multi-sampled i nstruments.
Velocity + CC
By enabling both ve locity and CC mod ulation contro l, the velocity r esponse can be
biased, brighter or dark er for instance, by the spe cied continuous controller. i s was
added so that users or develo pers could create a knob fo r overall tone control of a DEF
enabled instrument.
Also track lter envelope
It is possible to modulate the D EF with the EG2 (lter e nvelope). is is always in addition to the
assigned controller for the DEF – the values of the EG2 env elope and MIDI control ler are added
together.
e normal mu ltimode lters (Lowpass, High pass, Bandpass , Bandreject) DO NOT have to be
running for EG2 to mo dulate DEF. E G2 values below 5 0% are subtracted from the runi ng CC
value, and EG2 values above 50% a re added to the running CC value. e re sults of adding the
EG2 and CC values is subject to s aturation, so the eect ive value always stays withi n the standard
range of the Conti nuous Controller .
Example: If the EG2 is at it's peak (100%) value, there is no upward CC modulation possible; If the
CC value is increased it will not d o anything under this 'saturated' s ituation. However, decreasin g
the CC Value in this situation wi ll bring the saturated value b ack down.
Load from le
is option allows you to load a preset DEF conguration from a le. Several factory preset
proles are installed with GS4 and can be found in the f ollowing directory:
C:\Program Files\Common Files\TA SCAM\Giga\profiles\Dynamic Expres sion
Note that DEF preset les st ore information from th e region articulations as well as the instrument
global part of the DEF den ition.
Save to le
Saves a DEF con guration, includi ng both the globa l denition a nd region-level co ecients, t o an
initialization le that you can the n apply to other instrument s.
