Offset
Shift (time, key, velocity) by a specified number of units. For example, you could offset the start of a
track by two measures.
Overload
Loss of audio information caused by the audio level exceeding 0 db.
Pan
Degree to which a sound or piece of music comes from the left or right speaker. This control is
commonly used to adjust the level of a signal in different channels. In a stereo mix, the level is
adjusted between the left and the right speakers.
Patch
Particular sound in an electronic device. Patches are stored in banks, in groups of 128.
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.
