Macro montage (sort of) in Reaktor

This tutorial is mainly for my students at The Norwegian Academy of Music but everyone is welcome. If you have any comments or suggestions please e-mail me.
I prefer positive an constructive comments :-) after all I'm doing this for free (its not a part of my work at the academy to produce tutorials on the internet).

Macro montage (sort of) in Reaktor.
In this tutorial we will make a sort of micro montagegenerator using Reaktor. We will automate the process of cutting a sound file in small sound objects and place those short sound objects randomly in time. We will do no transposing this time.

Important!!!
This is a tutorial ensemble. Later on we will do a much more flexible and better functional ensemble using the Grain Cloud module.

This tutorial doesn't guide you from A to Z (from start to end) you have to take notes on the lesson to get all of the programming details. If you have some experience in Reaktor programming this tutorial will be simple to follow.

Even if this is pretty basic stuff, this tutorial contains some very fundamental basic programming concepts in Reaktor. You have to understand what happens in this tutorial in order to continue this course.

Listen to the video. This is what we are going to build.
It shows an Reaktor ensemble that randomly play 100 msec grains from a sound file.

You can download the source (the boy`s voice)file here.

Programming basics.
The ensemble we are going to make is a rather primitive ensemble but it will show you much of the basics programming in Reaktor. And please remember in all creative work there are many ways to come to a result, this is just one.
The only judge of how well the programming works is you. In my Reaktor granulation Tutorials you may see things that you think is bad programming and it’s definitely possible you could be right. There are so many ways of doing the same thing in Reaktor.

We are going to make an ensemble that:
play small excepts in a sound file randomly, using a Sampler FM module and a Random Oscillator.

-Open Reaktor as a Stand alone.
-Open a New Ensemble.
-Double click on the Instrument module. The structure window for the instrument then opens
Its her all programming will happen.

These are the modules we are going to use:

Important.
We are going to use a Random Oscillator to control where to start playing in a sample by connecting it to Sampler FM St(art) input.

Listen to the video,
here you can hear that we play small grains randomly at at regular time intervals. The first video had irregular time intervals.
We will start building an ensamble that play at regular time intervalls.

The videoes below,,
describes the programming you have to do to arrive to the result you heard above. It’s a large videoes!
Use the video pause button and Insert the module in Reaktor that the video talks about.

Before you start you should insert the modules shown in the illustration below, in the Instrument Module
(How to insert a module? Right click in the Structure window).

If there are any modules in the Instrument Module you should delete all but the outputs.

Inserting Modules:
Here is a little help with the two modules to the left.
The first module is an Log (F) module. Tis module converts from Hz to MIDI note number. You find this module in the Math folder.
Right click in the Instrument structure window a menue then pops up. Look at the window below.

The next moduleyou have to insert is the Random oscillator module.
You find this module in the Oscillator folder. Tis module outputs a random value. Right click in the Structure window and insert the module Random oscillator. Look at the illustration below.

The next three modules:
-Rectify is in the Math folder
-Single delay is in the Delay folder and
-Sampler FM is in the Sampler folder.

Part 1.
Listen to the (in not so very god) English voice. It guides you along the programming
,(there are some flaws in the text, but I haven’t the time to correct them remember I’m doing this for free……

Read the text below the Large Video download illustration, it lists most of the programming elements.

Double-click on Sampler FM and import (Add) a sample.
Make a controller to log, use the Log (F) module.
Log converts from frequency to MIDI note number.
Freq controls the how often the random oscillator changes its values.
Double-click on the newly created frequency controller and change values to something more appropriate, look at the video for my settings.
Make a connection from Log to Random P.
Make a connection from Sampler Len(gth) to Random A(mplitude).
Len(gth) outputs the sample length in milliseconds.
Random will then output values between 0 and the length of the sample in Sampler module.
Make a connection between Random and Rectify. Use the Rectify(x) module.
An oscillator outputs values between –x and +x. Negative values to the sampler FM St(art) is read as 0, the very start of the sample.
Rectify converts all values to positive values.
Make a connection between Rectify and Sampler FM St(art).

Part 2.

This is how the ensemble looks like at this stage:
Observe the five millisecond delay highlighted in reed, to the Single Delay module in the illustration below.

Also observe the Pitch controller to the Sampler FM module. Just right click on the P input an choose Create controller.

Grain Length.

Adjust the T 1(attack), T2 (sustain), and T3 (decay) controllers to your taste.

You defiantly need to adjust the T1 (attack) and the T3 (decay) controllers, otherwise you will (can) get clicks at the start and end of a grain.
The T2 controller controls the length of the grain 40 is approximately 100 milliseconds.

You should be able to solve these problems:

There will be additions to this text in the feature. Its being edited at this very moment :- )
