The Sensitivity menu of the External MIDI Mode offers the same functionality as the Sensitivity menu of the Sound Engine Mode. Read here to learn about it.  

However, there are some specificities in External MIDI mode that are explained below.

bending tab 

ℹ The bending range inside the bending tab isn’t shown as a number of semitones but as a fraction. It works together with the maximum bending range that can only ever be set inside the external software or hardware that you control.

Example: With the maximum bending range set to +-48 semitones in the target device (the most common setting in an MPE environment), 1/48 means that the effective range is 1 semitone.

velocity/press tab

ℹ In External MIDI mode, the velocity/press tab features additional velocity parameters. Internally, Osmose doesn’t use MIDI Velocity (MPE Strike) at all, but for controlling external devices, MIDI Velocity is derived from the Pressure axis motion.
