Calibration
All Three Body units come calibrated by us. If for some reason the calibration needs
to be redone (large temperature changes or to accommodate for the quirks of a
particular midi to CV controller) the steps are included below.
Please do not do this unless you are certain it is necessary as it will change both the
volts per octave scaling and the zero offset for the modulation indexes (making sure
the modulation can be turned off).
All input controls should be fully counter clockwise (FM INDEX, PHASE CV, PHASE
INDEX, FM CV)
Pitch controls should be at 12 o clock (COARSE/MULT, FINE/DIV)
Start with setting the voltage source to 0V:
Plug the cable into "FM" on the left oscillator, hit "LOW" calibration button
Move the cable into "PHASE 1" on the center oscillator, hit "LOW" calibration button
Move the cable into "PHASE 2" on the center oscillator, hit "LOW" calibration button
Move the cable into "FM" on the right oscillator, hit "LOW" calibration button
Plug the cable into "TRANSPOSE", hit "LOW" calibration button
Move the cable into "VOCT" left, hit "LOW" calibration button
Move the cable into "VOCT" center, hit "LOW" calibration button
Move the cable into "VOCT" right, hit "LOW" calibration button
the LEDs will now list the next oscillator in binary
000: FM left
001: PHASE 1 center
010: PHASE 2 center
011: FM right
100: TRANSPOSE
101: VOCT left
110: VOCT center
111: VOCT right
Change the voltage source to 4V:
Plug the cable into "TRANSPOSE", hit "HIGH" calibration button
Move the cable into "VOCT" left, hit "HIGH" calibration button
Move the cable into "VOCT" center, hit "HIGH" calibration button
Move the cable into "VOCT" right, hit "HIGH" calibration button
the LEDs will now list the next oscillator in binary
00: TRANSPOSE
01: VOCT left
10: VOCT center
11: VOCT right
The LEDs are read from top to bottom.
The calibration will update after the final “HIGH” calibration button press.
