lv2:documentation """
This is a vocabulary for describing a position in time and the speed of time
passage, in both real and musical terms.
In addition to real time (based on seconds), two units of time are used:
_frames_ and _beats_. A frame is a numbered quantum of time. Frame time is
related to real-time by the _frame rate_ or _sample rate_,
time:framesPerSecond. A beat is a single pulse of musical time. Beat time is
related to real-time by the _tempo_, time:beatsPerMinute.
Musical time additionally has a _meter_ which describes passage of time in
terms of musical _bars_. A bar is a higher level grouping of beats. The meter
describes how many beats are in one bar.
"""^^lv2:Markdown .
time:Position
lv2:documentation """
A point in time and/or the speed at which time is passing. A position is both
a point and a speed, which precisely defines a time within a timeline.
"""^^lv2:Markdown .
time:Rate
lv2:documentation """
The rate of passage of time in terms of one unit with respect to another.
"""^^lv2:Markdown .
time:beat
lv2:documentation """
This is not the beat within a bar like time:barBeat, but relative to the same
origin as time:bar and monotonically increases unless the transport is
repositioned.
"""^^lv2:Markdown .
time:beatUnit
lv2:documentation """
Beat unit, the note value that counts as one beat. This is the bottom number
in a time signature: 2 for half note, 4 for quarter note, and so on.
"""^^lv2:Markdown .
time:speed
lv2:documentation """
The rate of the progress of time as a fraction of normal speed. For example, a
rate of 0.0 is stopped, 1.0 is rolling at normal speed, 0.5 is rolling at half
speed, -1.0 is reverse, and so on.
