 Legato mode is used as a workaround for a limitation of MIDI (max 24 semitones pitch bend). Maybe some synth can perform pitch bend on more that 2 octaves but none of mine does...
 
+### With Legato Mode = ON and Pitch Bend Mode = OFF, the notes generated don't seem to be in a given scale. For example I can't play in C major if I select Pitch Bend Range = 2.
+Effectively according to the sequence described above (Fade-in / Picth Variation / Fade-out), the first note played influences the next notes played: they will always be distant of N * Pitch Bend Range. For example, with Pitch Bend Range = 2, if you start with a C and move the right hand, you can only play C, D, E, F#, G#, A#. This is as designed. 
+
+If you want to play in a given scale you need to set Legato Mode = ON, Pitch Bend Mode = OFF, Pitch Bend Range = 1 and to use a synth with a "force to scale" capacity (Some pluggins can do that, for example http://www.thepiz.org/plugins/?p=pizmidi midiForceToKey). Then select the expected scale and play. Out of scale notes will be replaced by the closest one in the scale.

 Changing this to your taste may require some test and trial.
