I tryed the FCB1010 a few years ago to control some plugins in cubase. The range of the expression pedals where really wrong and I didn't really liked the feel of it. The pedal have a really cheap feeling under the foot.
The range issue can have two causes:
* the physical range of movement in the pedal, which is a Bit limited compared to other swell pedals
* the data range not being properly setup/calibrated, which can be done either on the device it controls (like and ADA), or from the FCB menu (IIRC)
Regarding how the FCB swell pedals feels a Bit not uqite right under the foot.. this is because the part onto which the foot is resting is really a Bit too short.
When you place your foot on it, you'll automatically hit it in such a way that your foot sticks out on both ends, and this will make it feel wrong, simply because the angular movement now doesn't sit correctly under your heel/ankle.
Move the foot a Bit forwards, so the heel sits flush to the pedal, and it'll feel and work correctly.
This can easily be fixed by simply attaching a piece of something to the toe end of the pedal, thus making it longer, so that you'll automatically hit it correctly with your big boot.
