CV Calibration 

The 

Sampler’s

 

Pitch

 jack is factory-calibrated to respond at 1V/octave. 

However, there is a lot of variation amongst equipment, so if you want the 

Sampler

 to be in tune, we highly recommend calibrating the 

Pitch

 jack to your 

own equipment. Anytime you patch a different sequencer, keyboard, or 
controller into the 

Pitch

 jack (and you will be wanting the tuning to be accurate), 

you should re-calibrate. 

Calibration is quick and easy:

1. Unpatch the 

Pitch

 jack. It must be unpatched because part of the calibration routine is measuring 

the “offset” voltage when no CV is being input.

2. Next, hold down 

Bank

 and 

Reverse

 for one second. The lights will all turn blue. If they turn red, 

then you forgot to unpatch the 

Pitch

 jack.

3. Patch your sequencer, keyboard, or controller into the 

Pitch

 jack.

4. Play a C2 (2.00V)

5. Press 

Play

. The lights will turn magenta. If they turn red and then go back to normal colors, then 

the voltage read was not close to 2.00V. Verify this voltage and try again. Note that some 

controllers output 2.00V at C0 or some other octave, so consult your controller’s manual or try 

various octaves.

6. Play a C4 (4.00V)

7. Press 

Play

. The lights will turn green and fade back to normal colors. If they turn red, then read the 

note on step 5 and try again.

If you saw the lights turn green, then your calibration has been saved. The calibration will persist even 

after power down.

Calibrating CV jack offset 

For the other four CV jacks besides 

Pitch

, calibration is not normally necessary. However, in 

exceptional circumstances (using a noisy power supply, for example), you may want to calibrate the 
offset of these jacks. To do so, unpatch all CV jacks and enter 

CV Calibration

 mode as described 

above. Making sure all four CV jacks are unpatched, quickly press and release the 

Bank

 and 

Reverse

 

buttons at the same time again. These two buttons should flash green and then return to blue, 
indicating that calibration of these jacks is complete. At this point, you can continue the 

Pitch

 

calibration routine (starting at step 3), or you can press 

Play

 immediately to exit.

Start-up bank 

You can set the default bank to be loaded at start-up by editing the settings.txt file on the SD Card. 

Look for a section that looks like this:

[STARTUP BANK CHANNEL 1]

15

Edit the number (15 in the above example, but it might be any number on your unit), setting it to the 
number value of the bank you want the 

Sampler

 to start-up in.

For an example, See the 

System Settings File

 section page 15.
