Internally, the system figures out how the Oscillator is
routed to the Master Effects, and automatically adjusts
the appropriate send parameters.
Editing sounds & effects with the
Realtime Knobs
The Realtime Knobs are a traditional feature of KORG
workstations, combining modulation, quick edits, and
hands‐on control.
In R.TIME KNOBS/KARMA mode, knobs 1‐4 have
dedicated functions, as printed on the front panel:
Filter Cutoff, Filter Resonance, Filter EG Intensity, and
Release Time. All of these correspond to standard
MIDI CCs.
Knobs 5‐8 can be assigned to a wide variety of
functions, many of which also have corresponding
MIDI CCs. Often (but not always), knobs 5 and 6
modulate synthesis parameters, knob 7 controls the
depth of a chorus or other modulation effect, and knob
8 controls reverb depth.
Real‐Time Knob functions
Knob MIDI CC
1 74 Filter Cutoff Frequency
2 71 Filter Resonance
3 79 Filter EG Intensity
4 72 EG Release Time
5-6 Varies for each Program
7 Often Chorus Depth - but can vary per Program
8 Often Reverb Depth - but can vary per Program
When you move a knob, it sends out the corresponding
MIDI CC. Also, when the CC is received via MIDI or
generated by KARMA, the knob value changes to
match the CC value.
Generally, the knobs "scale" the Program's internal
settings. When the knob is in the center, the settings are
as programmed. To move the settings to their
maximum value, turn the knob all the way to the right;
to move them to their minimum value, turn the knob
all the way to the left.

Quick Edits using the Sliders, Knobs and Switches
This is an electric piano sound; let's see what we can do
to make it sound a bit different.
2. Press the R.TIME KNOBS/KARMA button under
CONTROL ASSIGN.
The button's LED will light up.
3. While playing the sound, turn knob 1 (Filter
Frequency) to the right, slowly, to about 3 o'clock.
Notice how the piano becomes a sort of synth sweep.
4. Next, turn knob 2 (Filter Resonance) to the right,
also to about 3 o'clock.
5. With knob 2 in that position, try moving knob 1
back and forth as you play.
With the resonance increased, it now sounds like
you're playing through a wah pedal.
Next, let's say that you decide that's not really what
you wanted–so, we'll set the knobs back to their
default values. You could move them back to the
straight‐up, 12 o'clock position, and then adjust them
so that they're exactly in the middle, but there's an
easier way...
6. Hold the RESET CONTROLS
button.
This button is under UTILITY,
between the MODE and BANK
buttons, to the right of the LCD.
7. While holding RESET CONTROLS, move first
knob 1, and then knob 2.
As you move the knobs, their values will be reset to the
default, center positions.
8. Release the RESET CONTROLS button.
Now, you're back to the original electric piano sound.
Knob edits can be saved
The Real‐Time Knobs are great for modulating sounds
in performance, or for recording. If you like, you can
also save the edited version of the sound, using the
normal Write Program command (see "Saving your
edits" on page 59).
Internally, a single knob usually affects several
different parameters. When you write a Program, the
edits are saved into the individual parameters, and not
to the knob itself. After writing the Program, you'll
notice that the knobs have returned to their center
positions–since the old "edited" values are now the
new "saved" values.
Assigning functions to REALTIME KNOBS 5–8
When the Control Surface CONTROL ASSIGN is set
to R.TIME KNOBS/KARMA, the four knobs on the
right function as Realtime Knobs 5‐8 (User 1‐4). These
can perform a number of different functions, such as
modulating sounds or effects, adjusting effects send
levels, and so on.
Each Program, Combination, and Song stores its own
settings for what the knobs will do. You can also make
settings for Sampling mode as a whole.
When using the knobs for AMS or Dmod, it's
important to understand that assignment is a two‐step
process. First, you assign the knob to send a MIDI
