Reaktor Core: Building a rising edge clock detector for a Counter

federico giuliani

Hi,

I am trying to learn Reaktor 6 Core with the goal of building my own Reaktor Blocks.

My first attempt is to take a clock signal and count its rising edges. I want to create a detector that outputs a single sample equal to 1 when the clock goes from 0 to 1, and then send that sample to the 'up' input of a counter.

However, I'm struggling to build this detector that generates a single sample of 1 at every rising edge of the clock.

I already tried using a Z-1 delay to compare the current sample with the previous one (using Current > Previous), but it's not working as expected.

The counter remains at zero. My hypothesis is that perhaps a single sample equal to 1 is too brief to be detected by the 'up' input of the counter.

Any suggestions on how to fix this?

Hello.

There was a Threshold Crossing macro in R5 which might be what you're looking for. It triggers an output event when input events rise or fall below a given level. I've used it regularly.

It, along with a bunch of other core macros, were dropped from R6. I don't know why. I've attached the entire set of them, many of which I've found to be very useful.

The Threshold Crossing macro can be found in:

Core Macros > Standard > Event Processing > Thld Crossing

If you put a constant of 0.5 on the comparing input, it will trigger an output whenever your clock rises from 0 to 1. A separate output will trigger when the input falls.

Also, the same directory has a Counter macro in it.
