The Bitstream 3X has two modes, which should prevent undesirable jumps:

Jump mode:
allows the instantaneous sending of MIDI data no matter what position 
the control is in at the time of the change.
This mode could provoke undesirable jumps in the values when the user 
uses the different groups of the Bitstream 3X, the physical value of the 
control may not correspond to the value of the same control in a new group.

Hook mode:
allows the user to avoid any undesirable jump in values: After any group 
change, if the physical position of the analog control doesn’t 
correspond to the value of the same control in the newly
selected group, the MIDI data is not sent while the physical position 
and the value are different. Thus, no jump in value is obtained.
The LCD screen of the Bitstream 3X indicates the direction to move the 
control to finally generate the MIDI.


They want to make the firmware and software open source btw (all though 
that thread may be old, it's still their plan to do so):
