CRAVE

page 3 of 6page 3 of 6

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).
