Q01 QC Test Procedures

Items required for test (one each unless otherwise specified):

• Q01 unit with current OS

• IEC power cable

• MIDI cable

• Sustain pedal

• Pair of headphones

• AP Computer w/ cables

Setup and Calibration:

1) Connect IEC power cable from Q01 to power outlet.

2) Connect the MIDI cable from Q01 MIDI OUT to Q01 MIDI IN.

3) Plug sustain pedal into the expression pedal input jack on the Q01.

4) Plug the headphones into the headphone output jack of the Q01 (marked with

a headphones symbol). Turn Master Volume knob (red knob) completely CCW.

5) Power up Q01 while holding down PAGE < and > PAGE buttons. This brings

the Q01 into diagnostic mode. Verify that the text “ diagnostic” appears at the very top of the LCD.

6) Using the > PAGE button, go to page 3 of the diagnostics (text at top of LCD

should read “ EXT IN AUDIO TEST” and text at bottom of LCD should read “ 3 of 3” ).

7) Press the soft button beneath “ whl cali p hi” text at the bottom of the LCD (text at top of LCD should now read “ WHEEL CALIBRATION” and the text “ whl cali p hi” should now be highlighted).

Pitch Wheel Calibration

8) Verify that there is an arrow pointing up towards a number, in a box labeled “ p.” Move pitch wheel “ p1” to its top-most position and press the “compare” button. This calibrates the top range of the pitch wheel.

9) Turn the encoder one click CCW. The arrow in box “ p” should now be pointing down towards another number. Move pitch wheel “ p1” to its bottom-most position and press compare. This calibrates the bottom range of the pitch wheel.

Mod Wheel 1 Calibration

10) Turn the encoder one click CCW. The arrow should now be pointing up in a box labeled “ m1.” Move mod wheel “ m1” to its top-most position and press “ compare.”

Page 19

11) Turn the encoder one click CCW. The arrow should now be pointing down in box “ m1.” Move mod wheel “ m1” to its bottom-most position and press “ compare.”

Mod Wheel 2 Calibration

12) Turn the encoder one click CCW. The arrow should now be pointing up in a box labeled “ m2.” Move mod wheel “ m2” to its top-most position and press “ compare.”

13) Turn the encoder one click CCW. The arrow should now be pointing down in box “ m2.” Move mod wheel “ m2” to its bottom-most position and press “ compare.”

Expression Pedal Calibration

14) Verify that the sustain pedal is plugged into the expression pedal input of the Q01, not the sustain pedal input.

15) Turn the encoder one click CCW. The arrow should now be pointing up in a box labeled “ exp.” Press the “ compare” button.

16) Turn the encoder one click CCW. The arrow should now be pointing down in box “ exp.” Press the sustain pedal and press the “ compare” button.

This concludes calibration.

17) Power cycle the Q01 while holding down PAGE < and > PAGE buttons. Verify that the text “ diagnostic” appears at the very top of the LCD.

18) Plug the sustain pedal back into the sustain pedal input of the Q01.

Procedures:

1) Visual Inspection

a) Inspect the front panel for dents and scratches. b) Make sure that the end caps are properly seated into the chassis. Verify

that they also don’ t have any dents any scratches.

c) Verify that all the jacks on the rear of the Q01 have nuts installed.

2) LED Test

a) Verify that the LCD displays the texts “ LED TEST” and “ all LEDs are on.” b) Verify that all the LEDs on the Q01 are indeed on and that the brightness

between LEDs of the same type/color is consistent.

c) Turn the encoder one click CCW (translucent white knob to the right of the

LCD). Verify that the LCD displays the text “ all LEDs are off” and verify that all LEDs turn off.

d) For all the exposed LEDs (the ones protruding through the front panel),

verify that they do not have any visible scratches.

3) Button/Sustain Pedal Test

a) Press the soft button beneath the LCD text “ button sust pdl.” Verify that

the LCD text “ button sust pdl” is now highlighted, and that the texts “ BTN/SUST PDL TEST” and “ press any button” are now displayed in the middle of the LCD.

b) Test all the buttons on the Q01 front panel EXCEPT for the following:

PAGE <, > PAGE, and the three soft buttons beneath the LCD (between PAGE < and > PAGE buttons).

c) When a button is pressed down, verify that the name of that button is

displayed on the LCD, and that the LCD indicates the button is pressed down with the text “ button DOWN.”

d) When the button is released, verify that the LCD indicates the button has

been released with the text “ button UP.”

e) As each button is pressed, make sure that the silk screen on that button is

not scratched or misaligned. Also verify that all the buttons have a consistent feel, and that they should generate one “ click” when pressed.

f) Press on the sustain pedal. Verify that the LCD displays “ sust pedal button

DOWN.”

g) Release the sustain pedal. Verify that the LCD displays “ sust pedal button

UP.”

4) Pot/Expression Pedal/Wheel Test

a) Press the soft button beneath the LCD text “ pot exp pdl.” Verify that the

LCD text “ pot exp pdl” is now highlighted, and that the texts “ POT/EXP PDL TEST” and “ turn any pot” are displayed in the middle of the LCD.

b) Test all the pots on the Q01 front panel except the Master Volume. c) When a pot is turned, verify that the pot’ s name is displayed on the LCD

and pot indicator moves smoothly. NOTE: If the pot is turned CW, the pot indicator will move from left to right, and the percent value will increase. Conversely, if the pot is turned CCW, the pot indicator will move from right to left, and the percent value will decrease. Also, some pots are more sensitive than others. This is normal and should not be considered a failure (i.e. the FILTER 1 FREQ pot is more sensitive than the FILTER 1 RES pot).

d) Also verify that there are no bumps or rough spots felt on the pot knob as

it is rotated CW or CCW.

e) Plug the sustain pedal into the expression pedal input jack of the Q01. f) Press on the sustain pedal and verify that the LCD displays the text “ exp

pedal” and the value “ 0” .

g) Release the sustain pedal and verify that the LCD now displays a value of

“16383.”

h) Move pitch wheel P up and verify that the LCD shows the text “ pitch

wheel” and a value of 16383.

i) Move pitch wheel P down and verify that the LCD shows a value of 0.

Page 21

j) Move modulation wheel M1 up and verify that the LCD shows the text

“ mod 1 wheel” and a value of 16383.

k) Move modulation wheel M1 down and verify that the LCD shows a value

of 0.

l) Repeat steps j) and k) with modulation wheel M2.

m) Verify that the “ref” value (displayed above the pot or wheel name) is

between 2500 and 3200 (typically it should be around 2800). Note that this value will change slightly as the pots and wheels are tested. This is normal, but the variation should be no more than +/-1%.

5) Keyboard Test

of 36, and that the rightmost key has a note number of 84 (the key’ s note number is displayed on the LCD when that key is pressed/released).

c) As each key is pressed, make sure that the key movement and feel is

consistent with all the other keys. Inspect the keys as well for scratches and dents.

d) When a key is pressed, verify that the note number of that key is displayed

on the LCD, and that the LCD indicates the key is pressed with the text “ key DOWN.”

e) When the key is released, verify that the LCD indicates the key has been

released with the text “ key UP.”

6) Encoder Test

a) Press the soft button beneath the LCD text “ encoder.” Verify that the LCD

text “ encoder” is now highlighted, and that the texts “ ENCODER TEST” and “ turn the encoder” are displayed in the middle of the LCD.

b) Turn the encoder CW. Verify that the LCD displays a positive number that

increments as the encoder is turned, and that the arrow is pointing to the right.

c) Turn the encoder CCW. Verify that the LCD now displays a negative

number that decrements as the encoder is turned, and that the arrow is now pointing to the left.

the LCD). Verify that the LCD displays “ passed.”

Page 22

8) Audio Output Test

a) While listening to the headphones, press a key and turn the Master

Volume knob clockwise until the tone is at a comfortable listening level (this verifies that the Master Volume pot is functional). Verify that both the left and right sides of the headphones produce a tone.

b) Plug the headphones into the Q01 main output left jack. Verify that when a

key a pressed, a tone is heard on one side (left side) of the headphones. NOTE: the Master Volume knob may require adjustment in order to hear this tone more easily.

c) Repeat step b) for the Q01 main output right jack, and the Q01 aux output

left and right jacks. Note that for the aux outputs, the Master Volume knob has no effect.

9) Voice DSP Test

a) Plug the headphones into the Q01 headphone output jack (Master

Volume knob may require readjustment to bring headphone output to a comfortable listening level).

b) Press and hold down a key (do not release). A single tone should be

heard from the headphones.

c) Press and hold a second key (do not release the first key) and verify that a

second tone is heard together with the first one.

d) Press and hold a third key (do not release the first and second key) and

verify that a second tone is heard together with the first and second ones.

e) Repeat step d) five more times, so that a total of eight notes are playing

simultaneously, each time verifying that the new note is heard along with the existing notes that are already playing.

10) External Audio Input Test

a) Press the PAGE > button once. Verify that the LCD text “ ext in” is now

highlighted (at the bottom of the LCD), and that the text “ EXT IN AUDIO TEST” is displayed in the middle of the LCD (there should also be a
