The Orinj Bouncing Echo is an echo in every sense of the word – the signal is repeated a number of
times with an ever decreasing amplitude. It is not a simple echo, however. It differs from the
simple Orinj Echo. In the simple Orinj Echo, the time between each two successive repetitions
is the same (there is constant delay) and the ratio of the amplitudes of each two successive
repetitions is the same (there is constant decay). The delays in the Orinj Bouncing Echo are not
necessarily constant. They may change with each repetition. Thus, the Orinj Bouncing Echo is an
echo with a delay sweep.
A practical example of this type of echo is a bouncing ball. Once the ball is dropped, it will
bounce faster and faster as time passes, as each bounce will be of smaller and smaller height. In
this example, the delays between each two successive bounces will become smaller and smaller.
Since the bounce becomes quieter and quieter, we can say that this is a natural echo with an ever
decreasing delay.
The delays of the Orinj Bouncing Echo are not completely random. If they were, we would have had
simply a collection of simple delays the parameters of which are independent of each other, which
is a tapped delay line. The delays for the successive repetitions of the Orinj Bouncing Echo are
not independent of each other. There is some relationship. In our practical example of a bouncing
ball, the delays may be decreasing by the same amount or the same ratio.
Using the Orinj Bouncing Echo
You can add the Orinj Bouncing Echo to tracks in
the multitrack session view,
tracks in the
loop building view,
and to waves in the
single wave view. In the multitrack session view
and in the loop building view, first select the track to which you want to add the
effect. In all of these views, click on Effect, Delay, and then on Orinj Bouncing Echo
in the Orinj menu. You will see the following dialog
with two tabs.

When this dialog becomes visible, the Orinj Bouncing Echo effect has been added. Adjust the
parameters of the bouncing echo in the dialog above and click Close. These parameters are
described below.
Orinj Bouncing Echo parameters
See Effects for an explanation of the Title, Track, Presets, and
Bypass controls. The remaining Orinj Bouncing Echo controls are described below:
-
Delay graph: The top graph shows the delay for each repetition. In the graph in the dialog above,
for example, the delay decreases between the original signal and the 15th repetition from 500
milliseconds (ms) to zero milliseconds. The first 15 repetitions then are an example of an
echo that resembles a bouncing ball. The repetitions come faster and faster one after the
other. You can use the graph to add additional points and to
move points up and down and left and right. To add a point, click anywhere on the graph where
you would like the point to appear. To move a point, click on that point and drag it. All
points in the graph are shown as small yellow squares, except the selected point. The selected
point is in white. The selected point can also be moved or removed with the remaining controls
of the dialog. (Note that if this graph has points that are vertically aligned and the lines
between them are horizontal, then the delays between repetitions are constant and the echo
becomes a standard echo).
-
Repetition: Use these controls – the box and the slider – to set at which repetition the
selected point should be placed. The selected point is the one that is in white in the top
graph. Each point can be placed at any repetition from 1 to 49. The two end points (the first
one and the last one) cannot be moved left or right. In the dialog above, for example, the
selected point is the first one and cannot be moved. It must remain at repetition 0. Thus,
the repetition controls are disabled. If you click on a different point to select it (e.g.,
the point at repetition 15 above), these controls will become enabled. As you change these
controls, the selected point in the top graph will move to the left or to the right.
-
Delay: Use these controls – the box and the slider – to set the delay of the selected point in
the top graph. As before, the selected point is shown in white. As these controls change, the
selected point will move up or down to show a larger or a smaller delay respectively. The delay
at any point, at any of the repetitions from 0 to 50, can be changed when this point is selected.
The delay for a specific point is the difference in time between the repetition at that point
and the previous repetition. (At repetition 0, we will obviously be describing the delay of
the original signal, which has no practical meaning. However, although the original signal has
no delay, a point at the original signal – at repetition 0 – defines the delays between itself
and the next point in the graph. In the dialog above for example, the fact that the delay at
repetition 0 is 500 ms defines the line between that delay and the delay at repetition 15 and,
hence, defines the delays of each of the repetitions between the original signal and repetition
15.) The delay is measured in milliseconds and can be between 0 ms and 1000 ms (1 second).
-
Remove: Use this button to remove the selected point in the top graph. The first and last point
of the echo cannot be removed. The selected point is the one that shows in white. When this
point is removed, nothing else in the echo will change. A new line will be drawn in the top
graph between the points to the left and right of the removed point.
-
Remove All: Use this button to remove all points in the top graph except for the two end points.
-
Max repetitions: Use this control to set the maximum number of repetitions that the echo should
have. Although, with some decay, the repetitions of the echo will be of ever decreasing
amplitude and, since Ornj works with wave PCM data, will eventually become of zero amplitude,
you may want to cut off the echo early. You can do so with this control. The maximum repetitions
can be between 1 and 50.
-
Decay graph: The bottom graph shows the impulse response of the echo. That is, it is a simple
graphical representation of the repetitions of the echo. In the example above, the bottom graph
shows 15 repetitions with ever decreasing amplitude and with an ever decreasing distance
between them (decreasing delay). This graph is there to show you the echo and cannot be used
to modify the echo.
-
Decay: Use these controls – the box and the slider – to set the decay of the echo. The decay
of the bouncing echo is constant, similarly to the decay of the simple Orinj Echo. The ratio
of the amplitude of the first repetition to the amplitude of original signal and the ratio of
the amplitude of each other repetition to the amplitude of the previous repetitions are the
same and are shown in these controls. The decay is measured in percent and can be between 0%
(complete decay, zero repetition amplitude) and 100% (no decay, each repetition is of the same
amplitude as the original signal).
See Effects for additional notes on: where Orinj effects can be
used, using boxes and sliders that control the same effect parameter, applying effects to mono and
stereo waves, and using effects during playback. See
Working with effects for additional information on
creating, modifying, moving, removing, and processing effects.
Dry and wet mix
The Orinj Bouncing Echo supports dry and wet mix changes. That is, you can adjust the mix
between the original signal and the echo. See Effects for more
information.
