The MONOPOLY has a built-in auto calibration function.
If the MONOPOLY is played through the keyboard or through MIDI, and you notice that the VCO is out of tune, it can be
calibrated by running the auto calibration procedure shown on this page.
If you are using external CV to control the MONOPOLY, and you notice that the VCO is out of tune, it can be calibrated using the
procedures shown on the following pages. If you do not feel comfortable doing these calibrations, then we recommend they
are done by an experienced audio service technician.
CAUTION: Incorrect calibration or damage to the delicate adjustment trimmers may lead to the unit becoming inoperable.
Note: Although re-calibration will not invalidate the warranty, any damage caused during re-calibration may invalidate
the warranty.

Introduction
Auto Calibration Procedure
To enter the automatic calibration mode, hold the EFFECTS button while powering on the unit. The VCOs will be calibrated in
sequence. If successful, each related VCO LED will ash; if not successful, they will not light up.
To return to the factory calibration, hold the HOLD and EFFECTS buttons while you power on the unit.
As mentioned above, if you are using the keyboard or MIDI to play, then this auto calibration is all that is required. If you are
using CV to control the MONOPOLY, and you think it may require tuning, then follow the procedures below.

Connect the guitar tuner to the rear panel output.
Leave the unit turned on for approximately 30 minutes. This will allow the circuits time to warm up and the
components and performance to stabilize with temperature. Without this warm-up time, the calibrations will be
inaccurate.
Preparation
Set the MONOPOLY controls as follows:
• Set MASTER TUNE, TUNE of VCO2, 3, 4 to the middle position
• PORTAMENTO to 0
• DETUNE to 0
• All OCTAVE to 8’
• WAVEFORM select the triangle waveform
• CUTOFF to 10
• RESONANCE to 0
• EG INTENSITY to 0
• KBD TRACK to 0
• VCA EG: ATTACK and DECAY set to 0, SUSTAIN and RELEASE set to 10
• NOISE to 0
• BEND and MG1 INTENSITY to 0
• Turn o the ARPEGGIATOR and EFFECTS
• Set key assign mode to MONO(UNISON)
• Set the OUTPUT VOLUME to 10 (switch to HIGH)
Connect the power and hold the HOLD and EFFECTS buttons while you power on the unit. This important step will set
the unit back to its factory calibrations before you can begin the calibration procedures below.
