Dynamic Keyboard Test
LED Vibes ON
The operator acts on keyboard, from right to left, with a dynamic range between levels 40/90; in the case the pressing
sequence is correct AND the detected value is in the specified dynamic level, the sound related to preceding key is
switched off and a note related to present key pressed is activated.
If the sequence is wrong OR the dynamic is not correct WAIT UNTIL CORRECT SEQUENCE AND DYNAMIC.
In order to repeat this test press the button VIBES.
When the first on the left side is reached the DEMO LED starts blinking waiting for the operator to press it and go to
next step.

Switch & leds
The first LED on the LEFT (relative to REVERB) BLINKING waiting for REVERB button to be pressed.
When the button related to the current BLINKING LED is pressed, the LED is switched OFF and next LED (from left
to right direction) is switched ON
In the case of VARIATION when pressing the button for first time it will switch ON the VARIATION LED on left.
Pressing the button for second time will light the VARIATON LED in the center. Pressing the button the 3 rd time it will
light ON the variation LED on the right.
In order to repeat this test press the button ORGAN 1.
When the DEMO button is reached, pressing it will switch to next step.
Tempo ADC Converter Test
LED Organ2 ON
Acting on TEMPO potentiometer, moving it in the left position will light ON the VARIATION LED in the LEFT,
moving it in right position it will light ON the VARIATION LED on the RIGHT, while the center position will light
ON the VARIATION LED in the center.
ONLY the VARIATION LED relative to potentiometer position will be light ON
The check on complete sequence (the LED ON in sequence) will make the DEMO LED blinking waiting for the next
step to be activated by operator.
In order to repeat this test press the button ORGAN 2
Damper Pedal Test
LED String ON
Operating on Damper Pedal, the position high will light ON the VARIATION LED on the LEFT, the intermediate
position will light ON the VARIATION LED in the center, and low position of pedal will activate VARIATION LED
on the right
ONLY the VARIATION LED relative to position will be light
After press the Damper some times, if pedal is not recognised, the STRING LED starts blinking
The check on complete sequence for pedal will make the DEMO LED blinking waiting for operator to press it and go
to next step.
When the DEMO button is pressed, (with only one pedal) the test is concluded and the system will be reinitialised, in
order to repeat this test press the button STRING.
