OSC SCALE
Connect an accurate, high-quality tuner to the VCA/LINE OUTPUT jack.
PANEL DEFAULT SETTING (FIGURE 1)
Set the panel settings as shown in Figure 1.
Remove all unnecessary cables from the unit.
Preparation
Make sure your CRAVE has been powered on for at least 1 hour, and that it is in a place where the temperature will not
change drastically while performing the calibration.
Follow all steps in the order in which they are presented.
Calibration Procedures

Adjust OSC OFFSET trimmer until the pitch is 440Hz (A4). Note that a pitch within 2 to 3 cents of the target frequency
should be ne. If the VCO pitch is still not correct after the adjustment is nished, you can calibrate the KB CV and
adjust it again as shown in the procedures above.
Set the keyboard octave to 6 and press “STEP6” key.
Adjust the panel OSC SCALE trimmer until the pitch is 880Hz (A5). Note that a pitch within 2 to 3 cents of the target
frequency should be ne.
Repeat steps 2 to 5 until output frequency is correct.
OSC OFFSET
Set the keyboard octave to 5 and press “STEP6” key.
Set the FREQUENCY control precisely to the center position.
Adjust the panel FREQUENCY control or OSC OFFSET trimmer until the pitch is 110Hz (A2). Note that a pitch within
2 to 3 cents of the target frequency should be ne; (OSC OFFSET trimmer and OSC SCALE trimmer location shown
in Figure 2).

End of Procedure
Press “HOLD/REST” to select test mode A. You need to watch the multimeter to adjust the KBCV voltage.
You can press “KYBD”or “STEP” to adjust the value until it close to target level“-5 V”(±1 mV).
(Press “STEP1”“STEP2”“STEP3” or “STEP4” to select the speed of adjust “X1”“X2”“X3” or “X4”)
Press “RESET/ACCENT” to select test mode B.
Press “KYBD” or “STEP” to adjust the value until it close to target level “0 V” (±1 mV).
Press “ARP/SETEND” to select test mode C.
Press “KYBD” or “STEP” to adjust the value until it close to target level “5 V” (±1 mV).
Press “REC” to save and nish CV calibration.
Calibration done, power o the CRAVE.
