1
00:00:00,800 –> 00:00:04,367
Let’s examine the join CHOP.
2
00:00:04,367 –> 00:00:12,533
I’ve set up 3 example networks
here, each network illustrates
different approaches to using
the join CHOP.
3
00:00:12,533 –> 00:00:17,500
In this network we will append 3
CHOPs together.
4
00:00:17,500 –> 00:00:24,367
We start with the ramp from 0 to
1, and end with a ramp from 1 to
0.
5
00:00:24,367 –> 00:00:27,667
In the middle we have a noise
CHOP.
6
00:00:27,667 –> 00:00:33,900
As you can see, the join CHOP
will stack one CHOP after the
next.
7
00:00:33,900 –> 00:00:44,800
Using the “Preserve Length”
method, with no blending or
overlap interpolation, the CHOPs
are simply appended together.
8
00:00:44,800 –> 00:00:51,767
We can better visualize the join
by changing the seed parameter
of the noise CHOP.
9
00:00:51,767 –> 00:01:00,767
By maintaining an overlap region
of 0, any overlap shape
parameter I choose has no
effect.
10
00:01:00,767 –> 00:01:02,967
—
11
00:01:02,967 –> 00:01:12,700
In the second example network,
we’ll look at the “Insert Blend
Region” option of the method
parameter.
12
00:01:12,700 –> 00:01:21,400
We join 3 chops with single
sample values of 0, 1, and .5.
13
00:01:21,400 –> 00:01:31,033
We can see that the join CHOP
has interpolated a simple ramp
between the incoming values.
14
00:01:31,033 –> 00:01:40,967
By using the “Insert Blend
Region” method, we can define an
overlap region between each
incoming value.
15
00:01:40,967 –> 00:01:47,567
We can also control the shape of
the overlap blend.
16
00:01:47,567 –> 00:01:59,767
As I increase the overlap
region, you’ll see that the join
CHOP creates a smoother and
smoother interpolation between
the incoming values.
17
00:01:59,767 –> 00:02:06,600
It does this by creating more
samples than the total of the
original inputs.
18
00:02:06,600 –> 00:02:16,533
It uses the extra samples to
create more fine tuned steps
between the original inputs.
19
00:02:16,533 –> 00:02:26,533
In this example we’ll use the
“Overlap Sequences” method to
join the to incoming waveforms.
20
00:02:26,533 –> 00:02:41,500
We’ll join a triangle and a sine
wave, and you’ll notice that
there is a disparity in the end
value of input 1, and the start
value of input 2.
21
00:02:41,500 –> 00:02:49,033
We want to interpolate between
these 2 values, to create a
smooth join.
22
00:02:49,033 –> 00:02:57,067
This is similar to adjusting
Bezier handles on keyframes, or
points on a spline.
23
00:02:57,067 –> 00:03:05,367
As I increase the overlap
region, you’ll see the join
become smoother and smoother.
24
00:03:05,367 –> 00:03:11,733
If I use the “Cubic”
interpolation method, I can
shift the bias.
25
00:03:11,733 –> 00:03:20,133
This will determine the
influence that either the first
or second input will have on the
overlap.
26
00:03:20,133 –> 00:03:30,233
The join CHOP parameters are
very powerful, and will allow
you to fine tune your blends to
an exact specification.
27
00:03:30,233 –> 00:03:32,233
