INTRODUCTION
QQ2 is a 4-channel CV quantizer for processing variable voltages between -3V and +7V and
outputting 1V/oct CV set to an assigned scale.
SPECIFICATIONS:
HP = 12
Depth = 33mm
CURRENT DRAW:
+12V = 143mA
+5V = 0mA
-12V = 25mA
REQUIREMENTS
In order to use the QQ2, ensure the case you are installing it into uses a eurorack
specification power supply and has enough available current to supply the module.
When connecting the power cable, align the red stripe of the cable with the indicated -12V
marker on the back of the module.

MOD SCREEN
ASSIGNED MOD PARAMETER
DISPLAYS THE NAME OF THE PARAMETER
THAT THE SELECTED MOD CHANNEL
CONTROLS.
MOD 1 CHANNEL ASSIGNMENT
IN THE SAME WAY THAT EACH QUANTIZER
CHANNEL CAN BE LINKED TO THE 4
SEPARATE SCALES, EACH MOD CONTROL
CAN BE ASSIGNED TO ANY OF THE 4
QUANTIZER CHANNELS.
MOD 2 CHANNEL ASSIGNMENT
SELECTED MOD CHANNEL
DISPLAYS WHICH OF THE MOD CHANNELS IS
CURRENTLY SELECTED FOR EDITING. IN THIS
CASE, MOD 1 IS HIGHLIGHTED.
HOLD ENCODER BUTTON 3/4 SECOND
MOD PARAMETERS
AS OF FIRMWARE VER. 1.04, THE
AVAILABLE MOD PARAMETERS ARE:
Transp PRE -TRANSPOSES THE INCOMING
CV BEFORE BEING QUANTIZED, ALLOWING
FOR INVERSIONS OF THE CURRENT SCALE
Transp POST -TRANSPOSES THE OUTPUT
OF THE ASSIGNED QUANTIZER CHANNEL
BY SEMITONE INCREMENTS AFTER
QUANTIZATION, ALLOWING FOR KEY
CHANGES
OCTAVE -SHIFTS THE OUTPUT OF THE
SELECTED QUANTIZER CHANNELS UP OR
DOWN ONE OCTAVE AT A TIME
SCALE ASSIGNMENT -ALLOWS THE USE
OF CV OR THE MOD DIALS TO SWITCH
BETWEEN THE 4 SCALES ('ABCD'). AT 0V
CV AND UNDER, THE ASSIGNED
CHANNELS WILL FOLLOW SCALE 'A'.

CHANNEL SETTINGS
THIS MENU GIVES YOU MORE IN-DEPTH
CONTROL OF CERTAIN ASPECTS OF EACH
INDIVIDUAL CHANNEL ON THE MODULE
MENU OPTIONS
THIS ALLOWS YOU TO CHOOSE WHICH CV INPUT JACK THE QUANTIZER CHANNEL IS FOLLOWING. BY DEFAULT, EACH
CHANNEL FOLLOWS IT'S OWN CV INPUT JACK, IE. CH1 = CV1; CH2 = CV2; CH3 = CV3; CH4 = CV4. THIS MAKES IT POSSIBLE FOR
ALL 4 QUANTIZER CHANNELS TO FOLLOW A SINGLE INPUT JACK.
THIS IS FOR SELECTING BETWEEN THE STANDARD QUANTIZATION MODE AND THE ARPEGGIATOR MODE.
SETS THE DIRECTION OF PLAY WHEN IN THE ARPEGGIATOR MODE.
AVAILABLE CHOICES ARE:
THE ARPEGGIO STARTS AT THE BOTTOM, AND INCREMENTS UPWARD THROUGH THE SELECTED SCALE UNTIL
THE HIGHEST NOTE IS REACHED. AT WHICH POINT THE SEQUENCE IS RESET TO THE LOWEST NOTE.
UP >
THE ARPEGGIO STARTS AT THE TOP, AND PROGRESSES DOWNWARD THROUGH THE SELECTED SCALE UNTIL THE
LOWEST NOTE IS REACHED. AT WHICH POINT THE SEQUENCE IS RESET TO THE HIGHEST NOTE.
DOWN >
THE ARPEGGIO STARTS AT THE BOTTOM, INCREMENTS UPWARD, AND UPON REACHING THE UPPER LIMIT,
REVERSES DIRECTION BACK DOWN THROUGH THE SCALE. THE NOTES AT BOTH LIMITS OF THE SCALE ARE
REPEATED UPON DIRECTION REVERSAL.
UP / DOWN >
UPON EVERY TRIGGER, A RANDOM NOTE WITHIN THE SCALE AND OTHER PARAMETERS SET WILL BE CHOSEN.
RANDOM >
THE SAME AS UP/DOWN BUT WITHOUT THE REPETITION OF THE FIRST AND FINAL NOTES OF THE SEQUENCE
UPON DIRECTION REVERSAL..
PING PONG >
SETS HOW MANY OCTAVES THE ARPEGGIATOR WILL RUN ACROSS. THE RANGE IS FROM 1 TO 5.
SETS THE NUMBER OF STEPS IN THE ARPEGGIATION SEQUENCE BEFORE IT IS RESET TO THE BASE NOTE. THIS OPTION
OUTRANKS THE NUMBER OF OCTAVES SELECTED, IE. IN A SCALE OF 7 NOTES AND 2 OCTAVES, IF THE NUMBER OF STEPS IS
SET TO 7 OR BELOW, THE SECOND OCTAVE WILL NOT BE REACHED.
SETS THE LENGTH OF THE TRIGGER OUTPUT OF THE CHANNEL. THE SELECTABLE RANGE IS FROM 10mS TO 1 SECOND.
WHEN A NEW TRIGGER OCCURS, THE TRIGGER OUTPUT WILL BECOME LOW VERY BRIEFLY, REGARDLESS OF THE TRIGGER
LENGTH, ALLOWING MOST OTHER MODULES TO STILL REGISTER THE EVENT.
THIS IS THE STANDARD MODE FOR EACH CHANNEL FROM THE FACTORY. CV SENT INTO THE CV INPUT WILL BE
MEASURED, PROCESSED AND A QUANTIZED VERSION WILL BE SENT TO THE OUTPUT OF THE CHANNEL.
QUANTIZER >
IN THE ARPEGGIATOR MODE, SENDING A TRIGGER TO THE TRIGGER INPUT OF THE CHANNEL WILL PROGRESS
THE ARPEGGIATOR TO THE NEXT STEP. IT IS NOT NECESSARY TO PATCH ANYTHING TO THE CV INPUT JACK.

NOTES FOR CALIBRATION:
MODULES ARE CALIBRATED AT THE FACTORY AND SHOULD NOT NEED
TO BE RECALIBRATED. IF YOU DO NEED TO RECALIBRATE, HOWEVER,
YOU WILL NEED ACCESS TO A VOLTMETER WITH AT LEAST 4 DIGITS.
NOTES WHEN UPDATING:
DURING THE WIFI UPDATE PROCESS, YOU WILL NEED ACCESS TO A
COMPUTER TO TRANSFER THE FIRMWARE FILE TO THE QQ2.
WHILE THE WI-FI IS ACTIVE, THE MODULE CAN DRAW AN ADDITIONAL
100mA OF CURRENT, SO MAKE SURE YOUR MODULAR POWER SUPPLY
CAN HANDLE THE EXTRA LOAD.
SETTINGS
CALIBRATE
ENTERING THIS MENU ALLOWS THE
CALIBRATION OF THE CV INPUT AND
OUTPUTS OF EACH CHANNEL, AS WELL AS
