Introduction
The unit is carefully calibrated at the factory. The performance may change over time or due to environmental changes,
and the following recalibration procedures can be used to bring it back to its factory settings.
Equipment required
1. A multimeter (with 1 mv resolution)
2. A 3.5 mm cable (mono or stereo should be ne)

Remove all unused cables from the MS-1.
Set the controls 1 to 8 to the position shown in the right hand column of this table.
Set all the other faders, knobs and switches shown in the photo.
Preparation
Make sure your MS-1 has been powered on for at least 30 minutes, and that it is situated in a place where the
temperature will not change drastically during calibration.

Press “Shift + STEP1” to start Internal CV calibration.
All of the sequencer LEDs will light up in sequence after this has nished.
Press “KYBD + STEP” then power on device. All the sequencer LEDs will light up.
Wait for calibration to nish.

Connect the Multimeter to CV Out as shown below.
Carry out the Internal CV Calibration before starting this Output CV calibration.
Press “Shift + STEP2” to enter user Output CV calibration mode.
Press “HOLD/REST” to select test mode A. You will need to watch the multimeter to adjust the output voltage.
Press “KYBD” or “STEP” to adjust the CV value until it is close to target level “0V”.
(Press “STEP1” “STEP2” “STEP3” or “STEP4” to select the incremental adjustment size “X1” “X2” “X3” or “X4”)
Press “RESET/ACCENT” to select test mode B.
Press “KYBD” or “STEP” to adjust the CV value until it is close to target level “1V”.
Press “ARP/SETEND” to select test mode C.
Press “KYBD” or “STEP” to adjust the CV value until it is close to target level “3V”.
Press “PATTERN/BANK” to select test mode D.
Press “KYBD” or “STEP” to adjust the CV value until it is close to target level “5V”.
Press “REC” to save and nish Output CV calibration.
