Using the RD-700GX As a Master Keyboard
You can make changes in tones by adjusting the settings of the
following five elements.
following five elements.
ATK (Attack Time Offset):
The time it takes after the key is pressed for a sound to reach
full volume.

DCY (Decay Time Offset):
This is the time over which the volume decays after the attack
is finished.

REL (Release Time Offset):
The time it takes after the key is released for a sound to
become inaudible.
become inaudible.
COF (Cutoff Offset):
Adjusts how much the filter is opened.
RES (Resonance Offset):
This boosts the portions in the region around the cutoff
frequency, lending a particular quality to the sound.
Excessively high settings can produce oscillation, causing the
sound to distort.

Portamento is a function that causes the pitch to change
smoothly from one note to the next note played.
The Portamento Time setting determines the time for the
change in pitch when the portamento effect is applied to the
sound. Higher settings will cause the pitch change to the next
note to take more time.

This setting determines how the
volume changes in response to
the velocity.
The volume is increased as the
keyboard is played with greater
force when a positive Value is
used; when a negative value is
selected, the volume decreases
as the keys are played with
greater force. If this is set to “0,”
the volume will not be affected
by the strength of your playing
on the keyboard.
