This covers some of the same territory as my Virtual Instruments magazine tutorial but goes more in depth about the clock and modulo operations, as well as featuring a sequencer driver macro that syncs to the host.

I was going to work some of this into the first chapter of a book - I still might - but decided I want to have this info freely available. That way people who want to write tutorials or instructional material on Reaktor don't have to keep reinventing the wheel to teach the basics.

I'm writing some more advanced tutorials and will be posting them at my blog,, in the coming weeks.

The tutorial is written with the expectation that the user will have at least some nodding acquaintance with the program, has done the very simple build-a-synth tutorial in the manual, and has already configured his audio out and so forth.

Update 1.4: Bug fix. I've added a second step filter before the output of the SeqDriver macro, to trap duplicate events. Also, thanks to Nicolaas Cottenie for catching an error in my explanation of the step filter.

Nice one! I have a dream! To build a "bass" part sequencer. Basically - a new sequencer / piano roll that works in any host with drag+drop import / export. This is step one!

My first tutorial, very good, easy to read, and fun. The modulo 'remainder' output needed some thinking about though when I switched on the 'information' and aimed it at the wire, took the numbers and did the maths it all became clear. I was rolling around the floor! all those numbers and they work out everytime, I was wowed, thanks.

Thank you SO MUCH for putting together this document (Basic Clock Demo). I'm just getting started with Reaktor and this is exactly what I needed! I did find the basic clock structures in other ensembles but had a lot of difficulty deciphering them. This document explains how and why everything works. You've saved me a lot of time in experimentation!

Good catch, Nicolaas. I'm updating the PDF accordingly.

This tutorial is 100% gold. You should have wrote the Reaktor manual!

I think there's a small mistake on page 4: it says that the default Tol value of a Step Filter is 1, while it's 0, which means that with nothing connected it blocks events with the same value as the previous event. In this example that has the same result as if you put a 1, but it's not the same when you work with non-integer values. At least i think...
