The implementation of the expression pedal on the ‘Factors
is a bit confusing and it took me a bit to understand how I was affecting the
operation by the way I was trying to use it.

I kept forgetting that the pedal ranges are set by heel/toe
positions and moving pots… I would be tweaking a sound and not give the ‘Factor
enough time to not have the range setting active….

Also, you need to power up the ‘Factor with the pedal connected
for a “calibration”. Don’t forget some pedals have a knob that sets their
range. My EV-5 has to be set at “0” for it to have full range. (Again, more
goofy ,non-standard nomenclature in audio gear…)

However, I have never experienced any “jumpiness” or other
problems AS LONG AS I have had a linear pot (or CV source).

I recommend getting all this sorted with an EV-5 or other
pedal that others have had good luck with first before you suspect a problem
with your ‘Factor.

It takes time but is worth the effort.

Oh yeah, the Moog MP-201 is off-the-hook good. I have not ventured into any midi experiments yet, but it does great things with my 'Foogers. Yet to connect to my Voyager…
