The button's LED will light. Now you can use the
knobs to modify the sounds and effects, and use the
sliders and switches to control KARMA.
You can use these controls regardless of the page
shown on the LCD display. However, there is a page
which provides more information about the Control
Surface assignments and values.
2. Go to the P0: Control Surface page by pressing the
Control Surface tab, located in the lower right of
the LCD screen.
This page shows all of the Control Surface sliders,
knobs, and switches, along with their current
assignments and values. When you move a controller,
the corresponding object in the LCD screen will also
Using knobs to vary the timbre
When the RT KNOBS/KARMA button is lit, the eight
knobs at the top of the Control Surface modulate
various aspects of the sounds and effects.
Knobs 1‐4 have dedicated functions, as printed on the
front panel: Filter Cutoff, Filter Resonance, Filter EG
Intensity, and Release Time.
Knobs 5‐8 can be assigned to a wide variety of
functions. Often (though 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.
For a detailed tutorial, see "Editing sounds & effects
with the Realtime Knobs" in the OG, under "Quick
edits using the knobs, sliders, and switches."
Using Tone Adjust
Tone Adjust lets you use all of the sliders, knobs, and
switches on the Control Surface to edit Program
parameters, like the knobs and sliders on an analog
synth. Each physical control can be assigned to any one
of a number of Program parameters.
The specific parameters available through Tone Adjust
will vary depending on the type of Program. HD‐1
Programs support a certain set of parameters; each EXi
also has its own set of parameters. The PolysixEX
works particularly well with Tone Adjust, so let's take a
look at it now.
1. In Program mode, press the button for Bank I‐A.
2. Select Program I‐A074 Phunky Power Bass.
This uses the PolysixEX.
3. Under CONTROL ASSIGN, press the TONE
4. Play the keyboard while moving sliders 1‐4 and
Notice as the knob graphics on the display move as
well. Sliders 1‐4 control the envelope shape; knobs 1‐2
control the filter cutoff and resonance.
5. On the display, press the Control Surface tab.
This page shows the assignments and values for all of
the sliders, knobs, and switches.
6. Press the Main tab to return to the main Play page.
7. Touch the PolysixEX graphic around the Cutoff
and Resonance knobs.
The display jumps to the main PolysixEX page.
8. Experiment with playing while using the Control
Surface sliders, knobs, and switches.
Notice how the graphics respond, as well. You can also
select a graphic control on the screen and edit its value
using any of the data entry controls.
Restoring the sound to its original state
When you're editing a Program, you can compare back
and forth between the edited and saved versions.
1. Press the front‐panel COMPARE switch.
The COMPARE LED will light, and the Program's
saved settings will be recalled.
2. Press the COMPARE switch again, to return to the
The COMPARE LED will go dark, and the sound will
return to the edited version. You can switch back and
forth as many times as you like.
Resetting individual controllers
You can also reset individual controllers to their saved
values, such as the vector joystick or any control
surface slider, knob, or switch. To do so:
1. Hold down the front‐panel RESET CONTROLS
2. While holding down the switch, move or press the
control that you'd like to reset.
3. Release the RESET CONTROLS switch.
The controller will be reset.
