TASCAM GigaEditor 4 Manual 201
e Custom PRF m ode (Portamento Reshaping Filter) of th e Legato Portame nto rule incorporates region
specic PRF lter setti ngs as well as extended port amento controls like slid e range, velocitiy sensitivit y, and
slide curve type.
How it works
To put it simply, th e user denes four lter setti ngs (Fc, Q0, Q0 H, 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 speci ed for every region and sub-region of an instrum ent.
