John,

Here it is (via Doug Wagner, so thanks should go to him as well):

Reply from Dieter regarding the 112.

The pitch resolution of the A-112 is 1/4 semitone and the whole pitch
range is 5 octaves (see A-112 information on our web site or the A-
112 manual). Consequently the 270 degree rotation of the pitch knob
is divided into 4x12x5 = 240 steps (4 semitones per octave, each
octave has 12 tones). This means that 1/240 of the rotation angle -
which is very small - will cause a pitch change of 1/4 semitone. If
the customer wants a more sensitive tune control the resistor R2 (is
now 100k) could be changed (e.g. 200k will result in half the
sensitivity). But then the range covered by the tune control will be
smaller.

If both A-190 and A-112 are adjusted correctly no problems should
occur. For the A-190 the adjustment is made as described in the
manual. For the A-112 the trimming potentiometer P3 is used to adjust
the scale.
