12. First startup routine

Make sure all the potentiometers are fully counterclockwise when turning 

on your Harlequin’s Context for the first time. Plug in the power cable and 

make sure the red side of the ribbon matches the -12V on the PCB. Now let's 

plug the module into your system and test it. The module identifies the first time 

it turns on and automatically starts the calibration, test and factory reset 

routines. 

Turn on your rack. The Harlequin’s display shows a “C” for calibration.

• Patch the channel A output into the CV input and press the Scene 1 button

• Patch the channel B output into the CV input and press the Scene 2 button

• Patch the channel C output into the CV input and press the Scene 3 button

• Patch the channel D output into the CV input and press the Scene 4 button

The calibration is now done and the Harlequin automatically switches to the 

test routine :

• Each output produces a ramp (saw up LFO)

• CV input positive voltage values are displayed on the 7 segment display

• When an active gate is received in the gate input, the screen turns off

Therefore, patch each channel’s output into the CV input (the 7 segment 

display will give values from 0 to F). Patch one of the outputs into the gate 

input (the 7 segment display should slowly blink).

To test the white and amber LEDs, press each of the eight buttons of your 

Harlequin’s Context. When pressed, each button lights an individual LED up.

The green LEDs show the potentiometer value by their intensity. Turn all the 

potentiometers fully clockwise until all the green LEDs are fully on. You will exit 

the test routine when all the potentiometers are fully clockwise.

Now hold the first Scene button until the display shows the letter “F”.

Press the Store button to start the Factory Reset routine. This operation will 

clear all the non volatile memory, slot by slot, and the display will show the slot 

currently being cleared (from 1 to G).

Once the Factory Reset routine is done, the module will start normally.
