However, with the Randomize option checked and
the range set to ±25 bpm, the result is a tempo map
that constantly and randomly changes between 95
and 145 bpm:
Randomization can be used in conjunction with
any curve
Randomization option is a check box option,
which means that it can be used in conjunction
with any of the tempo curves:
Controlling the degree of randomization
The Randomize option is ideal for adding “human
feel” to the tempos of a sequence. By controlling
the range over which the randomizing occurs, you
control the degree of that feel. You can specify the
range either as a percentage or as a range of bpm. In
either case, each tempo event generated is placed
randomly within the range.
Emphasis
This sub-option causes the tendency of the
randomization to be higher or lower within the
specified range. Thus, if you wish to randomize the
tempos within a certain range, but you wish them
to tend to be higher, use a positive emphasis; use a
negative emphasis if you wish them to tend to be
towards the lower end of the range. A value of zero
equals no emphasis, which causes the
randomization to occur evenly within the range.
The effect of Density on randomization
A Fine density setting causes tempo events to be
generated more frequently than a Course density
setting. Notice that these two settings have an effect
on the constant tempo curve, which normally only
produce a single tempo event.
The Options button
Pressing the Options button cycles through the
different combinations of entered/computed
parameters for the selected curve. This allows you
to specify the curve in a variety of manners. For
example, if you select a constant curve, you can
specify just the tempo or you can specify the End
time, in which case the tempo will be calculated to
make the end measure location occur at the end
time.
If you are not working with externally imposed
timings, as required in film and video work, you
will probably not need to use the Options button.
A polynomial tempo curve with no randomization.
The same curve with randomization set to 2%.
