Hi Frank,
Our FC7 did arrive and out of the (old) box the behaviour was as you described. With an extra unwanted behaviour: volume was set between 0 and 63.
Fortunately the fix is easy: train your pedal.
Procedure is in the manual on page #59 :
Go to Global #8 (foot controller 1) or #9 (foot controller 2), hit a pad, set your pedal to the MAX, hit a pad, set your pedal to the MIN, hit a pad.
This way you can set the action as you like. Toe down for maximum volume as you like. But the other way around is also possible.
And training of the pedal also fixes the controller range. After training volume can be adjusted with the pedal from 0-127
Hth,
Ton
