The two signals look very similar, but if you look closely, the top one has a smoother transition when the LFO restarts. I retriggered the LFO in the middle of the section of the graph shown. I set the transition time to 20 ms (8 Events), and grabbed the following screeshot:
The top Event Table is recording all the events from the Event Smoother, and the bottom Event Table is recording the events straight from the LFO. I built the following structure to take a look at what the LFO was doing: After some thought, I wondered if an Event Smoother would help the situation. Recently, while working on a project that contained an LFO modulating various parameters, I determined that the LFO was causing pops and cracks if I set it to restart on a new MIDI gate. As shown above, you can translate the Control Rate into milliseconds by calculating 1000/x, where x is the Control Rate. If you choose to change the transition time, it makes sense to keep it as a multiple of the Control Rate. The transition time defaults to 100 milliseconds, which means that a new value received at the input of the Event smoother will take 40 events (100 ms/2.5 ms = 40) to fully transition to that value. By default, the Control Rate is set to 400 Hz, which comes out to one event every 2.5 milliseconds (1000 ms / 400 Hz = 2.5). The Event smoother is one of the few modules in Reaktor that outputs a continuous stream of events, the speed of these events is determined by the Control Rate (in the Settings Menu). This value is the amount of time in milliseconds it will take to transition to a new value received at the input. The Event Smoother module has a value in the FUNCTION tab of the properties called transition time. Here, the solution is simple – just add an Event Smoother between the Level knob and the Lvl input of the mixer: When the multiplier drops (or rises) very quickly, it creates a discontinuity in the waveform, typically referred to as aliasing. In this case, the Level of the Mixer module is being translated into an amplitude value, which is multiplied against the incoming audio.

It is useful to think about why this happens, when determining how to fix the problem. If you create this structure and quickly turn the Level knob while playing a note, chances are you’ll hear some pretty bad audio glitches in the form of cracks and pops. Here’s one of the most common examples of a problem that can be solved with the use of an Event Smoother: I’ll identify some of the most common problems and show how to fix them. There are several modules in Reaktor that will respond poorly if the knobs attached to them are not properly set up. Not only will Reaktor 6 Blocks give you some fantastic sounds with endless possibilities, as you connect up the wires to create your own patches, you'll also be subliminally learning the fundamentals of synthesis.In this tutorial, I’ll cover the topic of using Event Smoothers to eliminate audio glitches and bugs from your Reaktor ensembles. We then look at adding oscillators, filters and LFO's, create chords and pads along with percussive sounds and see how we can get the most out of the plugin within our chosen DAW.įinally, we check out some of the more interesting and useful 'blocks' and see what this powerful plugin is capable of. In this course Rory starts with checking out the user interface before moving on to building a basic patch. This fascinating and awesome plugin from Native Instruments - where you build your very own virtual modular synths from the ground up, will see you diving down a rabbit hole of sound creation and losing many happy hours before you know it! Sonic Academy welcomes back Rory from Hyper Production this week for in depth look at How To Use NI Reaktor 6 Blocks.
