Have any other A112 owners noticed that the tuning pot is EXTREMELY 
sensitive?  At a setting of 4, the very slightest touch knocks mine 
out of tune by approx. a semitone, which is especially noticable when 
trying to use it as a wavetable oscillator.

Thanks,
Kevin

I received an answer to the question (thank you Dieter).  The problem 
seemed to stem from a combination of the A112 and the A190.  Both are 
adjusted correctly now, and I'm enjoying 8 bit grind and terror.

Regards,
Kevin

Hi Kevin,
Mine is same but I can't check it at the moment as it's patched up 
for a song which seems to be taking me too long to write.
Any chance you could post dieter's reply so I can understand whats 
going on?

Thanks
John.

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.
