TASCAM GigaEditor 4 Manual 201
e Custom PRF mode (Portamento Reshaping Filter) of the Legato Portamento rule incorporates region
specic PRF lter settings as well as extended portamento controls like slide range, velocitiy sensitivity, and
slide curve type.
How it works
To put it simply, the user denes four lter settings (Fc, Q0, Q0H, V0) for each of the Up Long, Up Short,
Down Short and Down Long intervals using the PRF editor tab. e PRF then tracks the currently running
pitch of a sample and continuously morphes between these “Up interval” and “Down interval” lter points.
Unique PRF lter settings can be specied for every region and sub-region of an instrument.
Loading a factory PRF prole
Creating accurate PRF proles from scratch can be an involved process, for this reason GS4 includes a
nominal set of factory PRF proles for dierent instrument types that are easily applied to any 24-bit
instrument. To load a factory PRF prole to an instrument, rst select the Custom Legato Mode in the
Mono Mode Rule Dialog then navigate to the “Portamento Reshaping Filter Tab” and click ‘Load from le’.
Factory PRF proles are installed in the following directory:
C:\Program Files\Common Files\TASCAM\Giga\proles\Portamento Reshaping
Select and open the appropriate factory PRF prole then hit ‘Apply’. Aer clicking ‘Apply” you will be able
to audition the loaded prole. If you are working in the Editor, PRF proles can be saved permanently into
a .gig le instrument. If you are working in GigaStudio however, PRF proles can only be saved into a .gsi
(GigaStudio Instrument) or .gsp (GigaStudio Performance) and are not stored in the original .gig
instrument.
