MIDI processing and quantizing
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 and effects (see “MIDI
realtime parameters and effects” on page 315). For exam-
ple, the operations “Transpose” and “Quantize” are avail-
able as MIDI modifiers as well as MIDI functions.
The main difference is that MIDI modifiers and effects don’t
affect the actual MIDI events on the track in any way, while
MIDI functions change the events “permanently” (although
recent changes can be undone).
Use the following guidelines to decide which path to
choose for operations that are available both as modifiers
or effects and as functions:
• If you want to adjust a few parts or events only, use MIDI
functions. The MIDI modifiers and effects 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 and effects.
• MIDI modifiers and effects settings are not reflected in
the MIDI editors, since the actual MIDI events aren’t af-
fected. This can be potentially confusing; if you’ve e.g.
transposed notes using modifiers, 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 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 function only apply to MIDI events of a certain
type.
For example, quantization affects notes only, while the Delete Controllers
function obviously 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.
The Quantizing functions
What is quantizing?
Quantizing in its fundamental form is a function that auto-
matically moves recorded notes, positioning them on ex-
act note values:
However, quantizing is not only a method of correcting er-
rors, it can also be used creatively in various ways. For ex-
ample, the “quantize grid” does not have to consist of
perfectly straight notes, some notes can automatically be
excluded from quantizing, etc.
Ö When quantizing MIDI, only MIDI notes are affected
(no other event types).
However, you can choose to move the controllers together with their re-
spective notes by activating the “Move Controller” option in the Quantize
Setup dialog, see “The Move Controller setting” on page 328.
For example, if you record a series of eighth notes, some of them
may end up slightly beside the exact eighth note positions.
Quantizing the notes with the quantize grid set to eighth notes
will move the “misplaced” notes to exact positions.
