TASCAM GigaEditor 4 Manual

With Aftertouch chosen as the DEF Modulator source, it is possible to offset the filter curve by a
value between 0 and 64. When the minimum Aftertouch Offset value of 0 is used, the incoming
aftertouch values utilize the full dynamic range of the DEF filter curves. When the maximum
Aftertouch Offset value of 64 is used, the incoming aftertouch values are scaled to morph between
only the moderate (mf) and loud (ff) filter curves.

DEF Filter Coeffi cients

Th e remainder of the DEF filter settings are stored on a sub-region basis in the articulation data found in
the Editor’s parameter list:

Th e PRF and DEF filters were designed to address and emulate the characteristics of samples whose pitch
and dynamics have been transposed. For this reason, this musically adapted filter does not behave like a
traditional EQ; the settings of one parameter affect the next. Experimentation is encouraged. It might also
be helpful to use a Frequency Analysis Plug-in at first to get a feel for each filter parameter.

Giga’s morphing filters are composed of four independent parameters that affect the overall shape and
volume of the filter: cutoff frequency, Q, Q0H, and V0. Each parameter has a range of 0 to 127. Th e first
three parameters affect the timbre of the filter (frequency and Q) while the fourth parameter (V0) is used
for volume compensation.

Cutoff

Frequency

(Fc)

– Determines the initial center frequency for the Q0 Quality factor.

Q

– Simultaneously determines gain, Quality (filter width) and a center frequency offset relative to

the initial Fc setting.

Q0H

– This high frequency quality factor has a fixed center frequency near 7.5 khz and is

especially helpful in de-emphasizing the harsh overtones of upwardly transposed samples.

V0

– Initially designed to compensate for any gain attenuation imposed by the filter, V0 can also

be used creatively to increase the dynamic range of an instrument, achieving softer pianissimos
and bolder fortes.

DEF morphing capability:

Th ere are three “sets” of the four parameters explained above for each of an instruments sub-regions. Th ese
three sets of filter parameters (pp, mf, and ff) were designed to correspond to the dynamic range of an
instrument and represent the minimum, median, and maximum DEF settings as defined by the filter
modulation sources:
