I was looking into this the other day for my Pfaff and found this on their website http://www.pfaff.com/us/8574.html at the bottom of the page it lists the machines it's compatible with, unfortunately my Triptonic 2040 was not listed so that's about as far as I got with it.

I tried the Bernina BSR and actually did not like it. Whatever it is i do, the BSR did not work for FMQ. It was easier to learn my rhythm and go with my Pfaff.
