Now how about I like this effect so I want to keep it as a permanent effect. To do so I can drop pins to make the new object easy connectable. One on each side.
Just select the objects and right click - select Group.
Groups are already a nice self contained super-objects. You can move it around, minimize it and connect as a single object and save it to library.
Groups are still transparent to editing and "open", you can select inside objects, move them, change parameters or even connect some outside object right in the middle of it.
You can however completely wrap the group to a closed locked box called a Device if you want to have effect that is "finite". It is not necessary step, but a nice thing to wrap effects for future.
Device will hide all wires and expose only pins and any UI object that can be controlled from the workplace. In this case it is Curves and Knob. The analogy is like making a small electronics device and putting the controls on the top face-plate and hiding all the wires and mess inside the box. The box is a bit big right now but we can select Edit Inside and then use make Circuit.
This will place all non UI elements on a virtual circuit board as an single object. Now just move the UI components around Rename the pins and go to back to main editing. You have a Device. As a bonus you can customize the face plate with any of your image.
Now simply add it to the library and there it is, your own new effect that creates a dreamy look. The device is just a single file that you can share with others, it is self contained effect.
From now on you use the new effect as any other object, just drag it on the canvas. Connect it to more complex workflows without much regard what is inside.
I got a bit overboard with the screen, I just added bunch of stuff.
It would be probably much better to wrap things that go together into groups, pull out only necessary parameters - well practically the same thing we did when making the first device, but now the device is part of a much larger workflow.
On the workspace you can name connections, create pins and put text labels. Also there are instruments like monitors and vector/wavescopes that can be placed anywhere.
Unlike normal editing where the pile of layers become a deep secret on its own after a while, with Reaktor, the editing is always in front of you and all is always editable.
It is all dynamic and all it is also a "macro" without doing anything else. By clicking or loading any other image, the whole flow will be applied to it. Similarly you could just apply it to a bunch of files.
