1. First steps in Reaktor Core - Native Instruments

7.4. Building a rising edge counter macro
Now we are going to discuss a sign comparison technique which you might
sometimes need in building Reaktor Core structures. Sign comparison is a
special way of comparing two numbers, in which you ignore their values and
pay attention only to their signs (plus or minus). Naturally, plus is considered
greater than minus. So for example:
3.1 is sign-greater than –1.4
2.1 is sign-equal to 5.0
4.5 is sign-equal to –2.9
Beware that the sign of zero is undefined, which means that result of
any sign comparison involving a zero value can be arbitrary.
Of course you could have implemented the sign comparison using several
Comparison modules and several Routers, but there is a more efficient way.
The sign comparison can be done in Reaktor Core structures using the Compare
Sign module (Built-In Module > Flow > Compare Sign):
This module produces a BoolCtl signal at the output, so that you can connect
it to a Router.
One of the possible uses of such a module is detecting the rising edges of an
incoming signal. Below we are going to build a rising edge counter Reaktor
Core macro:
Note that the output is set to integer mode because the count is an integer
value.
The first thing we are going to need inside is an edge detector macro to convert
the detected edge to an event:
This is how the detector macro can be implemented:
