TASCAM GigaEditor 4 Manual 203
Upward tuning reference
Selects the PRF’s ‘Upward long’ interval tuning reference. 1-31 = specied in semitones, 0 =
defaults to octave. e ‘Upward short’ interval tuning reference is xed at a minor third (3
semitones).
Downward tuning reference
Selects the PRF’s Downward long interval tuning reference. 1-31 = semitones, 0 = defaults to
octave. e ‘Downward short’ interval tuning reference is xed at a minor third (3 semitones).
Velocity -> Time
Selects the amount of portamento time modulation determined by note-on velocity (0-127). 0 =
none, 127 = max. With this parameter set to a value other than 0, lower velocities will result in a
slower slide rate and higher velocities will result in a faster slide rate.
Velocity Response
Selects the velocity response for the target note (0-127). With this parameter set to 0, the target
note (destination of slide) will sound with the same velocity as the original note. With this
parameter set to 127, the target note is subject to the full rage of the instruments velocity response.
0 = none (original), 127 = max (full velocity response).
Velocity Pullback
Determines the degree to which the PRF lter response is reduced (attened) based on incoming
note-on velocity. 0 = no lter pullback, 127 = full pullback range. With this parameter set to 127,
an incoming note velocity of 127 will use the full value of the PRF lter coecients while lower
velocites result in a atter lter response.
Slide Curve type
Selects the portamento slide curve type, either nonlinear bell-type(acoustic) or linear (synth).
Note: Because GigaStudio streams samples directly from your hard drive, transposing a sample more
than three octaves above it’s root can cause unexpected results…
PRF Intervals and Filter Coefficients
ere are four lter sets associated with a PRF prole which correlate to pitch intervals: Upward Long,
Upward Short, Downward Long and Downward short. Each of these interval sets contains four parameters
(Fc, Q0, Q0H, V0) which are explained below. As a sample is transposed up and down the keyboard, the
PRF continuously tracks the samples pitch and morphs between the appropriate interval sets.
Upward Long – Controls the target lter settings for the Upward Long Interval as dened by the
‘Upward Tuning Reference’ value.
Upward Short – Controls the target lter settings for the Upward Short Interval which is xed at
three semitones.
Downward Short – Controls the target lter settings for the Downward Short Interval which is
xed at three semitones.
