Knob Modes
KNOB MODES
For all knobs with the exception of 
MASTER VOLUME, you can select 
from four operating modes in the 
CTRL menu. These are located  
under the menu item KNOB 
MODE:
 
OFF    The knobs are inactive.
 
JUMP    In Jump Mode, the 
parameter jumps directly and 
absolutely to the value determined 
by the current position of the knob.
 
SNAP    When you adjust a knob 
In Snap Mode, the original setting 
determines the value until the 
point where the movement of the 
knob passes beyond this position. 
In other words, the parameter does 
not jump to the value as in JUMP 
Mode. However, keep in mind that 
your adjustments have no effect 
on the parameter until the knob 
“snaps”  on at the position equiva-
lent to the original value. In SNAP 
mode, an ®-symbol appears to the 
right of the number. It indicates in 
which direction the VALUE knob 
must be turned to exceed the cur-
rent parameter value. 
 
RELATIVE    When you adjust a 
knob in RELATIVE Mode, the 
parameter is affected immediately 
but not absolutely.  In other words, 
the value change from the original 
value to the value reflects precisely 
the amount you adjusted via a 
given control. Generally this oper-
ating mode allows you to adjust a 
parameter immediately, without 
radical jumps. However, the down 
side is that in an unfavorable con-
figuration - the worst-case sce-
nario being a maximum parameter 
value and a knob position at the 
minimum value - you do not have
