MIDI Transform window presets
The table below describes the operations performed by the MIDI Transform window presets.
Preset Operation
Random Pitch Sets a random pitch for note events. Change the Pitch condition values to
alter your selection range.
Random Velocity Sets a random velocity for note events. Change the Velocity condition
values to alter your selection range.
Random Pitch, Velocity, Length Sets a random pitch, velocity, and length for note events. Change the
Pitch, Velocity, and Length condition values to alter your selection ranges.
Crescendo Used to gradually increase the velocities of a group of notes from low to
high values (or vice versa—decrescendo or diminuendo).
•
Select the area (Position column) that contains the note events that
you want to perform a crescendo on.
•
Set the velocity values in the Operations area, ranging from 1 to 127.
•
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. This preset is a useful creative option for drum regions. Change
the values in both fields to 4.000 to quadruple the tempo.
Half Speed Halves the tempo by doubling event positions and lengths. The Mul(tiply)
value fields for the Position and Length operations are set to 2.0000 by
default. Set both Mul operation value fields to 1.5000 to reduce the tempo
by approximately 30%.
Humanize Adds a random value to the position, velocity, and length of selected note
events. This preset is useful on rhythmic parts, such as clavinet, piano,
drum, and percussion. It can add life to strictly quantized material, or
manually entered notes.
Alter the values for Position, Velocity, or Length to increase or decrease the
random factor for each of these event parameters.
Reverse Position Reverses the positions of events (usually notes) within a section. Change
the Position condition values to alter your selection range.
Reverse Pitch Inverts the pitch of all note events. Change the Flip operation value to
set a pivot point note number, around which note event pitches will be
reversed.
Transposition Transposes all note events.
•
Change the Add operation value to the required amount (in semitone
steps).
•
Set a negative value in the field for a downward transposition.
