The obvious thing to do now is to make the second group
“Realtime Controls B”, but since we’ve gone over rotary
knobs already let’s try a few other Korg Triton controls.
Adding control objects – faders
The Triton has a slider called “Value” (commonly known as
a data entry slider), whose function is doubled by two but-
tons, increase and decrease. To mimic these controls we
need a Fader and a Data Entry object.
1. Switch to Faders on the Objects menu, then drag and
drop a vertical fader into the edit area.
The Parameter window appears.
2. Create a new parameter called “Value” (CC 18, Gen-
eral Purpose 3).
To edit the “min” and “max” labels on the fader, double-click on each la-
bel and enter “0” and “127”, respectively.
3. Select Data Entry from the Objects menu.
4. Pick one of the objects featuring up/down arrows and
drag it to your panel.
In the Parameter window that pops up, don’t create a new
parameter.
5. Instead, click on the previously defined parameter
“Value” in the list and then click OK.
When the same parameter is assigned to two or more
controls, the controls become linked so that when you
move one of them, they all follow.
We’re almost done. Let’s add a couple of switches as well.
Adding control objects – switches
1. Select Switches from the Objects Menu and drag a
switch from the On/Off subcategory to the edit area.
Unlike faders, knobs and data entry objects, switches can
only send two values. Normally, hardware controls that
function like switches only respond to 0 and 127, or 0 and
64. The Min and Max values in the Parameter window cor-
respond to the two alternate states (on/off) of the switch.
The Korg Triton’s realtime controls SW1 and SW2 respond
to CC 80 (General Purpose 5) and CC 81 (General Pur-
pose 6), respectively.
2. Define the two parameters and assign them to the
switches, SW1 and SW2.
Now we’re nearly there, but before we might want to test it.
