Trimming
Step 1: Use a multimeter and a small flat
screwdriver. Measure at the measurement
point as shown in figure 11. Trim the
potentiometer until a voltage of about
10.6V is set.
Step 2: Connect a Midi keyboard and play A
notes. Measure the output pitch voltage on
channel 1 (See figure 12).
Play note A in different octaves until you
have a note A, which is close to 4V.
Trim it to exactly 4.000V (or as close as you
can get).
Figure 11: 10.6V start point
Figure 12: A4 should be 4V. (Octave can
differ)
