1. First steps in Reaktor Core - Native Instruments

Now let’s take a look at another example using a true event signal:
The above structure implements a kind of pitch modulation effect. The effect
is produced by a delay whose time varies in the range 250±100 ms. The
rate of variation is determined by the Rate input, which controls the rate of
the modulating LFO (the value is in Hz)—that is a pure control signal. The
Rst input is a true event signal and can be used for restarting the LFO. The
incoming value specifies the restart phase, where 0 would restart the LFO at
the beginning of the cycle, 0.5 in the middle, and 1 in the end. You can try it
out by connecting a button to send a specific value to this input.
2.7. Logic signals
Now that we have learned about control and event signals, it’s time to learn
about another way of using signals in Reaktor Core, that would be as logic
signals. Here’s an example of a module that processes logic signals:
Notice that the ports of this module are integer type, just as was the RM input
of the envelope. That is because, generally, logic signals carry only integer
values; more precisely, they carry only values of 0 and 1.
For logic signals, a value of 1 stands for true, and a value of 0 stands for
false. The meaning of “true” and “false” is, of course, up to the user; for
instance, it could mean (as in the example here) whether a particular gate is
open (true) or closed (false):
Here a Gate2L macro checks the incoming gate signal and produces a true (1)
output if the gate is open and false (0) output if the gate is closed.
We can use logic signals to do logical processing. For example, here we’ve
built a gate processor that applies a regular clocked gate over a MIDI gate:
