MIDI realtime parameters and effects
The Inspector sections
Transpose
This allows you to transpose all notes on the track in semitones. The available range is
-127 to +127 semitones, but remember that the total range of MIDI note numbers is
0 to 127. Furthermore, not all instruments can play back notes over the whole range.
Therefore, extreme transpositions can give rather strange and unwanted results.
• You can also transpose individual MIDI parts using the Transpose field in the info
line.
The transposition in the info line (for the individual part) is added to the transpose
value you have set up for the whole track in the Inspector.
Ö This setting is also affected by the global Transpose settings. For detailed information,
see the chapter
“The transpose functions” on page 161.
Velocity Shift
This setting lets you change the dynamics of all notes on the track. The value in this
field is added to the velocity of each note message that is sent out (use negative
values to lower the velocities). The range is -127 to +127 with 0 representing no
change in velocity.
Note that the effect of changing the velocity depends on the sound and instrument.
Ö You can also adjust the velocity of events in individual MIDI parts using the Velocity
field in the info line. The velocity shift in the info line (for the individual part) is added to
the velocity shift you have set up for the whole track in the Inspector.
Velocity Compression
This function multiplies the velocity values with the factor you specify. This factor is set
using a numerator (left value) and a denominator (right value), resulting in a fractional
number (1/2, 3/4, 3/2 etc.). For example, if you set the factor to 3/4, the velocities will
be three quarters of their original values. This will also affect the difference in velocity
between the notes, thus compressing or expanding the velocity scale. Typically, you
would combine this setting with the Velocity Shift parameter.
An example:
Let’s say you have three notes with the velocity values 60, 90 and 120, and wish to
“even out” the velocity differences somewhat. If you set the Velocity Compression
value to 1/2, the notes will play back with the velocities 30, 45 and 60. By adding 60
in the Velocity Shift field, the notes will play back with the velocities 90, 105 and 120,
meaning you have compressed the velocity range.
In a similar way, you can use Velocity Compression values greater than 1/1 together
with negative values in the Velocity Shift field, to expand the velocity range.
Length Compression
This value adjusts the lengths of all notes on the track. As with Velocity Compression,
the value is set with a numerator and denominator. For example, the value 2/1 means
that all note lengths will be doubled, while 1/4 means all note lengths will be a quarter
of the actual lengths.
!
Remember that the maximum velocity is always 127 no matter how much you try to
expand.
