Apple Logic Pro 9 - Manual (Page 730)

• If you want a less dynamic crescendo, set a smaller value range.
• To perform a diminuendo, set a higher value in the top Velocity field, and a lower value
in the bottom field.
Scale 14 Bit PitchBd
Scales pitch bend data, keeping the 14-bit information intact. The length of pitch bend
events is expressed as a decimal value ranging from −8192 to 8191, and this is the 14-bit
information that is retained.
• Choose the multiplication factor for the fine pitch bend (LSB) and effective pitch values
(MSB) in the top value field shown in the Operations area.
• Set the (14 bit) value in the lower field, which is then added to the scaled (multiplied)
events.
Double Speed
Doubles the tempo by halving event positions and lengths. By default, the Div(ision)
value fields for the Position and Length operations are set to 2.0000.
Change the values in both fields to 4.000 to quadruple the tempo.
