Re: [vintagesynthrepair] minimoog pitch center detent

2011-02-23 by PeWe


Yes,- there´s a original MOOG "dead zone" mod for the pitch wheel center detend.
Have a look at the files section and leave a note if you don´t find it there.
Can be I have it somwhere on my machine too,- but that needs a search 1st.
Can´t promise, but I will have a look over the day.

In my Mini,- there´s different mod,- more like the one that works in a Prophet 5 and it works reliable since decades.
But that was done by a tech being out of biz since 2 decades or more.
I have his hand drawn sheets too somewhere, but I´m not sure it will be well readable for others and I have to find these too before I could do a scan.

Hi all,
I have a minimoog in for minor service/calibration from a
professional. Low serial number, and in very good shape.
The owner wants to have a larger center detent on the pitchbend wheel,
and playing the mini I kind of agree: it is a bit hard to fint the
exact center spot.
The center detent "click" is there, and careful playing in the studio
is fine, but on the fly live I can imagine some strange off-tune
unwanted sideeffects.
I think I remember seeing some mod to augment the center of the
pitchwheel, but I can´t seem to find this. Anyone heard of this?
It is the standard, early thin white pitch and mod wheels with smooth
surface.
Also, applying large amounts of pitchbend causes the VCOs to bend
apart in pitch. I don´t think there is an individual calibration for
this, so I will have to dig into the CV-summer and see what is wrong,
I think.
