Thank you!
After some excellent customer service from Schneiders Buero I received a replacement Doepfer adjusted fp5 pedal which works perfectly with the a177.2- and it's a joy to use.
Creating and controlling modulations through hands AND feet I feel I am finally able to fully 'play' my a100- a wonderful feeling.
To anyone else thinking of getting this module I would heartily recommend it - I love my a100!
