Hall effect CV pedals (was: Volume pedals for CV discussion)

[John Blacet]

LINEAR Hall effect sensors are a bit uncommon. The DIGITAL ones are more
common, being used for switches. Cherry semiconductor used to make a
linear version (I have a couple in the antique IC bin.)

The main problem with the linear version is that some memory device
would be req'd to be useful for a pedal effect unless a "go to zero"
output is OK when your foot is removed. They may also have some
temperature and process variations, but I have not seen the spec sheet
lately.

As far as Allegro goes, not familiar with them....
