MIDI processing
Introduction
This chapter describes the various MIDI processing func-
tions available on the MIDI menu. They offer various ways
to edit MIDI notes and other events, either in the Project
window or from within a MIDI editor.
MIDI functions vs. MIDI modifiers
In some cases, the result of a MIDI function can also be
obtained by using MIDI modifiers, see “MIDI realtime pa-
rameters” on page 233). For example, the operations
“Transpose” and “Quantize” are available both as MIDI
modifiers and as MIDI functions.
The main difference is that MIDI modifiers do not affect the
actual MIDI events on the track in any way, while MIDI
functions change the events “permanently” (although re
-
cent changes can be undone).
Use the following guidelines to decide which path to
choose for operations that are available both as modifiers
and as functions:
• If you want to adjust a few parts or events only, use MIDI
functions. The MIDI modifiers affect the output of the
whole track (although they can be made permanent in a
specific area with the Merge MIDI in Loop function).
• If you want to experiment with different settings, use
MIDI modifiers.
• MIDI modifiers settings are not reflected in the MIDI edi-
tors, since the actual MIDI events are not affected. This can
be potentially confusing; if you have transposed notes using
modifiers for example, the MIDI editors will still show the
notes with their original pitch (but they will play back at their
transposed pitch). Therefore, MIDI functions are a better
solution if you want to see the effects of your editing in the
MIDI editors.
What is affected by the MIDI functions?
Which events are affected when you use a MIDI function
depends on the function, the active window and the cur-
rent selection:
• Some MIDI functions only apply to MIDI events of a cer-
tain type.
For example, quantization only affects notes, while the Delete Controllers
function only applies to MIDI controller events.
• In the Project window, the MIDI functions apply to all
selected parts, affecting all events (of the relevant types)
in them.
• In the MIDI editors, the MIDI functions apply to all se-
lected events. If no events are selected, all events in the
edited part(s) will be affected.
Transpose
The Transpose item on the MIDI menu opens a dialog with
settings for transposing the selected notes.
Semitones
This is where you set the amount of transposition.
Scale Correction
Scale Correction transposes the selected notes by for-
cing them to the closest note of the selected scale type.
This can be used for creating interesting key and tonal
changes, either by itself or in conjunction with the other
settings in the Transpose dialog.
• To activate Scale Correction, click the checkbox.
• Select a root note and scale type for the current scale
from the upper pop-up menus.
• Select a root note and scale type for the new scale from
the lower pop-up menus.
Make sure to select the correct root note if you want to keep the result in
the same key as the original notes, or select an entirely different key if you
want to experiment.
