Strange mod on a CS60?
2011-11-13 by Max Fazio
Hi all
The group seemed a bit quiet for some time so I'd like to talk about a strange find under the lid of a friend's 60.

to look at the picture.
As you can see, I found a bridge linking the panel's control of ADSR's Release and Level (the slider next to R); it does seem a 3.9 Kohm resistor,the bridge has a jacket so the work looks like a professional one while not a factory's own modification.
The fact is that this design, which replaces the common link with the black cable, gives out altered voltages at the Level stage, with a +2-+9.1V range, quite departing from the usual 0/+10V. As you can understand this has an influence on the touch response system in the CS-60; more strange if you consider that anything in the preset section has been modified to match these voltages; so may I ask you if anybody else found such a mod, what could be the purpose of it and if anybody found anything similar on an 80..
Thanks for any insight
