Hi again,
To add to mac's posts ...
If you want to play around with setting the range of the pitch bend, the controls are found as follows ...
Click on "Melody" on the uppermost menu (#1), select "Edit Melody Track" (#2) and then choose "Utilities" (#3) from the sub-menu.

From this next sub-menu that pops up, select "Change pitch bend range".

The above assumes that you are recording your midi input on the Melody track.
Regards,
Noel
