Glossary
Pedal mark
Expression mark indicating when the player should hold down the pedal and release it.
Phase
Frequency dependent time delay. All frequencies experience phase, but as a whole this is not
noticeable as they are affected uniformly. If frequencies fall out of phase, however, they interfere
with each other constructively or destructively. This can be measured by calculating the period
length, as well as amplitude and magnitude values of a recorded wave form. If two frequencies fall
180 degrees out of phase, they will enduce destructive interference and thus completely cancel
each other out.
Pitch bend
Controller that changes the pitch of a MIDI note.
Pitch marker
A marker in the Time Ruler which transposes the root note pitch of all groove clips and ACIDized
loops in a project.
Pitch wheel
Controller that changes the pitch of a MIDI note.
Port
Computer connector for sending or receiving data.
PPQ
Abbreviation for Parts per Quarter Note. MIDI sequencers divide each beat into fractions of a beat
(called ticks) for timing and editing purposes. You can place events in precise timing locations, up to
the sequencer’s current PPQ. PPQ is adjustable on most sequencers, up to about 960 PPQ. PPQ
values of 96, 120. and 480 are common.
Project pitch
Also known as the default project pitch. The project pitch is the pitch that all groove clips and
ACIDized loops in your project follow if there are no pitch markers in the project. You can set the
project pitch with the Project > Set Default Groove Clip Pitch command.
Property
Any attribute or value belonging to an object. Often you can see these by right-clicking on the object.
Track and clip properties can be set in the Inspector.
Quantize
Correct human imperfection in start and duration of selected notes so they line up with a specified
time grid.
Quantize resolution
Used to set how precise (in notes or ticks) you want applying quantization to be.
