The Custom PRF mode (Portamento Reshaping Filter) of the Legato Portamento rule incorporates region specific PRF filter 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 defines four filter settings (Fc, Q0, Q0H, V0) for each of the Up Long, Up Short, Down Short and Down Long intervals using the PRF editor tab. The PRF then tracks the currently running pitch of a sample and continuously morphes between these “Up interval” and “Down interval” filter points. Unique PRF filter settings can be specified for every region and sub-region of an instrument.

Loading a factory PRF profile

Creating accurate PRF profiles from scratch can be an involved process, for this reason GS4 includes a nominal set of factory PRF profiles for different instrument types that are easily applied to any 24-bit instrument. To load a factory PRF profile to an instrument, first select the Custom Legato Mode in the Mono Mode Rule Dialog then navigate to the “Portamento Reshaping Filter Tab” and click ‘Load from file’.

Factory PRF profiles are installed in the following directory:

C:\Program Files\Common Files\TASCAM\Giga\profiles\Portamento Reshaping

Select and open the appropriate factory PRF profile then hit ‘Apply’. After clicking ‘Apply” you will be able to audition the loaded profile. If you are working in the Editor, PRF profiles can be saved permanently into a .gig file instrument. If you are working in GigaStudio however, PRF profiles can only be saved into a .gsi (GigaStudio Instrument) or .gsp (GigaStudio Performance) and are not stored in the original .gig instrument.
