A Unit Delay delays the wave by one sample (1/44100 second
for a sample rate of 44100 Hz).
For a triangle wave, we add the triangle and its delayed version.
This will just get the sum of two samples, actually averaging, since
the amplitude of triangle is 0.1.
This is a low-pass filter (simple moving average).
This is the structure view:
This is the panel view:
This is the Audio specturm of triangle (left) and triangle
+ unit delayed triangle (right):
We can see the higher frequencies are attenuated.
A Sawtooth wave is composed of many frequencies.
We use 1-Pole Filter, 2-Pole Filter and 4-Pole Filter to remove
the higher frequencies (since we get the Low Passed signal
out). The increasing number of poles will attenuate the
higher frequencies more.

This is the panel view (We enabled the View option
for each of the 3 filters from the Properties):
In the last example, we saw the steps in Slow Random output.
Should we not want that, we can use an Audio Smoother so
it will interpolate in-between values.

This is the Audio view showing changes at sample rate:
A Slow Random module will output a random wave
at control rate with the F parameter indicating the frequency
of randomness.
The output goes to scope and Audio out.

A Mouse Area module gives information about the mouse such
as the X and Y location.
From the View tab of Properties for the Mouse Area, the
Style is set as Frame, and Transparency Inactive and
Transparency Active (indicating if mouse within associated
panel area or not) is set to 0.
In most case, the Mouse area will be over some other
module and thus the default invisible setting is OK.

A 8-Step Sequencer, 12-Step Sequencer and 16-Step Sequencer
will oscillate between 8, 12 or 16 different levels. It is
similar to the 6-Step Sequencer (Example 69).
This is the structure view:
A 6-Step Sequencer will oscillate between different levels. It is
similar to the 6-Step oscillator (Example 60).
The levels are 0, .5, -.5, 0.75, -0.75 and -0.25. Then they keep
on looping. The BPM is the default 120, so each beat is 0.5 second. However,
the clock rate (Sync Pls.) is 1/8 note (1/2 beat) or 0.25 second. Thus 6
steps would correspond to 1.5 second for the period.
This is the structure view:
This is the panel view (showing 1 sec view of the 1.5 second periodic wave):
This is the Audio view:
From File->OSC Settings, we can find the receive port # and local
IP address.
We have to use the port # and IP address in external program which
will generate OSC messages.
In the Connect tab of OSC Recieve or OSC Rcv Array, we can set the
address pattern that it will listen for.
Using OSC Send or OSC Send Array, we can set generate
address pattern and values for output for external program.
This is the structure view:
A Level Meter will indicate level of signal in dB.
The Level Meters, Level1 and Level2, have a range -20 to 0, set
in the Function tab of the Properties.
We have two knobs, also named Level1 and Level2. Their range
is from 0.1 to 1. The dB value = -20 * log10(val). Thus 0.1 is -20 dB,
1 is 0 dB.
This is the structure view:
This is the panel view with Level1 knob set for 0.5 and Level2
knob set for 1:
The MIDI out section of modules allow for sending MIDI signals
as well as clock signals.
These are Note Pitch and Gate, Pitchbend, Controller, Chan. AT
(Ch. Aftertouch), Poly AT (Poly Aftertouch), SelPolyAT
(Sel. Poly Aftertouch), Program Change, Start/Stop, Clock
(1/96 Clock), Song Position and Channel Message.
We could generate the MIDI signals in one instance of Reaktor in
a DAW and another could be receiving the MIDI signals.
This is the structure view:
The PitchBend, Controller, Chan. AT, Poly AT, SelPolyAT and Prog.
Ch. can give MIDI information about these variables.
This supposes that you have MIDI device connected and send
those messages.
This is the structure view:
A Sync Pls. will send events at a rate determined by BPM, and
setting values in the Properties for this module.
In the Function tab, make sure its rate is 1/4 (every beat), and
the duration is smaller like 1/16.
If the BPM is 60 it will count at 1 second when the play is active.
This is the structure view:
This is the panel view after 187 seconds:
This BPM is changed to 60 and play is active:
In the Sampler we can load different audio files, as well assign different
MIDI pitches to them, so they may be played by MIDI keyboard or computer keyboard.
From the Panel view, right click on the Sampler and select a file.
It was mapped to MIDI 0 and thus to play original sound send 0 to P input
of Sampler.
It has been connected to output port to make sound.

The IC Send and IC Receive can set wireless connections.
In the Connect tab of Properties you can set the Internal Connections.
Here we connect IC Send to both ICR1 and ICR2, the two IC receive modules.

The 5-Ramp, 6-Ramp, and 8-Ramp oscillator work the same as 4-Ramp
(example 46) except with more levels to ramp to.

The 5-Step, 6-Step, and 8-Step oscillator work the same as 4-Step

A Sine oscillator is amplitude modulated by Clock Oscillator.
The Sine has a frequency of 100 Hz or 10 ms period. The scope is set to view
2 periods, with time scale of 20 ms.
It goes through a H-Env so each value is held for 1 ms.
This is the structure view:
This is the panel view showing 20 hold values of 1 ms each:

A Saturator 2 will limit output using soft saturation, with inputs
for the level of knee hardness, etc.
We use a Sine wave with amplitude of 8. This is fed directly to left
channel after division by 8.
The right channel gets output after saturation with kH of 0.8, and
then division by 8, so the two channels can be compared.

A Send can send a wireless signal.
The two Send modules are renamed Send1 and Send2.
Two receive modules are used. In the Function tab of Properties,
make sure the Connect is to proper receive in Send Terminals.

A LFO works at control rate, which is default of 400 Hz.
The LFO has options for outputting Sine, Triangle or Pulse.
We choose Sine. Because a 5 Hz wave, repeats 5 times per second, we
see 5 periods in a Scope with a time scale of 1 second.

This is the Audio view (By zooming you can see it updates after
about every 110 samples, 44100/110 is about 400):
A Chan. Message will give the MIDI message such as Note On, Program
Change, etc.
Since we only use computer keyboard, the only message we get is Note
On. The Note Off message is indicated by velocity of zero.
We always get Channel 1, as this is the default channel as we have
not connected any external device or changed the settings.

This is the panel view, as q is being pressed:
A ST Gate will limit trigger to first key pressed, when multiple keys
are being pressed.
We illustrate this by pressing letters q and z, at the same time for
5 different times.
The regular Gate will record all 10 note-on events while the
monophonic ST Gate will only record 5 note-on events.
