Vdf Keyboard Tracking - Korg i40M User Manual

R (Release level)
[–99...+99]
Sets the level at which the VDF cutoff frequency will
arrive after the Release Time (RT) has elapsed.
Page 7: VDF keyboard tracking
VDF keyboard tracking is a function that adjusts the
cutoff frequency according to the keyboard location of
the note that is played. On many real-world instru-
ments, higher notes have a brighter tone, and this can
be simulated using VDF keyboard tracking.
The effect of the tracking function is determined by the
Keyboard Track Amount, Pivot Key, and Mode param-
eters.
Keyboard tracking can be used to modify VDF EG
times, so that the four EG time parameters will be
shortened or lengthened depending on the location of
the keyboard that you play.
VDF1/VDF2 Amount
Time amount
Attack time
VDF1/VDF2
When a double oscillator program is selected, this
selects the oscillator whose filter parameters will be
edited.
You can also use the VARIATION [1] or [2] buttons to
switch between oscillators 1 and 2.
KbAmt (Keyboard track amount)
[–99...+99]
Specifies how greatly keyboard tracking will affect the
cutoff frequency. The way in which this will function is
determined by the Mode parameter, explained below.
Pivot key
Decay time
Release time
Slope time
Set it in the same way as the Attack Level parameter.
Positive (+) settings will cause the tone to become
brighter as you play above the Pivot Key. Conversely,
the tone will become darker as you play below the
specified key.
Negative (–) will have exactly the opposite effect.
With a setting of –50, the cutoff frequency of the note
specified by the Key parameter will be used as the
standard cutoff frequency for all notes, meaning that
the cutoff frequency will remain the same for all areas
of the keyboard.
With a setting of 0, the cutoff frequency will change in
direct correspondence to the pitch. This will produce
the same effect as when the following Mode parameter
Mode
is turned OFF.
Pivot key
[C-1...G9]
Sets the note which will be used as the center for the
keyboard tracking function. The function of this key is
determined by the setting of the Mode parameter,
below.
Mode
[OF, LO, HI, AL]
This determines the range which will be affected by
the keyboard tracking function.
OF (OFF) will cause keyboard tracking to be exactly
proportional to the keyboard pitch, just as when Key-
board Track Amount is set to 0.
LO (LOW) will cause keyboard tracking to apply to
the range below the Pivot note.
HI (HIGH) will cause keyboard tracking to apply to
the range above the Pivot note.
