Preset Operation
Exponential Velocity Alters the scaling of the velocity curve. This preset is useful for software
or MIDI instrument parts. Velocity is often used to control both the initial
volume of instruments and to trigger filter envelopes, making the sound
brighter or darker. Transforming regions can be faster than changing
velocity scaling or filter parameters of your MIDI or software instruments.
Change the Velocity value field in the Operations area to change the
velocity curve. This is reflected in the map area.
Velocity Limiter Limits the velocity to a maximum value. This is useful for transforming
instrument parts that are too strident, by limiting the velocity. Change the
Max operation field value to limit the velocity to a maximum value. This is
reflected in the map area.
Fixed Note Length Creates constant note lengths. Useful on many instruments, particularly
drums and other rhythmic parts, such as pianos, clavinets, and basses.
Change the Length value field in the Operations area to resize all selected
events to the chosen length. Both shorter and longer events are changed
to match the specified length value.
Maximum Note Length Sets the maximum length of all note events. Change the Length value
field in the Operations area to define the maximum note length. Existing
notes that are shorter than the length defined in the Length field retain
their lengths. Events that are longer than the defined value are reduced in
length.
Minimum Note Length Sets the minimum note length. Change the Min value field in the
Operations area to define the minimum note length. Existing note lengths
that are longer than the length defined in the Min field retain their
lengths. Note events that are shorter than the defined value are increased
in length.
Quantize Note Length Change the Length value field in the Operations area to define the length
that note end positions are quantized to.
