Reaktor 5 Tutorials – Tutorial 1 Part 1

Building your first synthesizer in Reaktor

hello everyone and welcome to my first I guess actual reactor 5 tutorial 5.5 specifically from Native Instruments and what you see here if you watched my last video what is a synthesizer called synth 1 and if you want to know more about how the program works and stuff I recommend you watch that first video but anyway in this video we're actually going to get into making art our very own synthesizer from the bottom up and so to begin we are going to you can't see this on this window but up in the right-hand corner on both a Windows on a Mac click file new ensemble and this window pops up and so you basically start with something that looks kind of blank and that's good and now just double click anywhere on this this screen here just double click like that and all those who you see this instrument here right just for any reason in case this doesn't show up for whatever reason I'm going to show you how to make your own instrument so this is basically the foundation of how you start building your synth here is this instrument so I'm going to delete it by hitting backspace not delete on the keyboard and for a Mac I think it's a referral windows I think it's the week but on the back its back spacers I don't know try try both and see a backspace and then right click on the screen and scroll down to instrument and you want to put in a new two in two out just like that and that connect these modules together by click and dragging clicking and dragging over to the left channel from in one and over to the right channel from it – and then out from left and right on the instrument – out one and out – and this goes to whatever your computer speakers are set up to be and reactor so pretty easy to set up there anyway now double click and you'll be inside the instrument and you'll notice this set up here this is our starting point for the actual internals of our instrument so what we're going to do first is we're going to make an oscillator and what an oscillator is is basically it creates a waveform and the most common waveform used in creating synthesizers is the sawtooth but you probably recognize some of these other ones like sine triangle and pulse wave which is like a square wave so we'll click sawtooth for now let's select a sawtooth oscillator and if you look at it you see has two inputs and one output and if you click over here to this check mark every select left you'll see left to show up here click sawtooth you'll see sawtooth show up here and then if you click info you could view the properties of whatever the module you want to select it so at the sawtooth in particular says oscillator for sawtooth signal with logarithmic pitch control P which is this and linear amplitude modulation a which is this and so what those are well you can think of pitch as a note you hit on the keyboard and so we're actually going to add that module right now so right click go to built in module MIDI in no pitch and it'll select the snow pitch module so click and drag this little wire thing over and release what you get over pitch and then you connect these two things now you're gonna know that's the pitch and that's how you control the pitch but I'm gonna show you something right now make sure the volume on your computer is low either by lowering the output up here or turning down the volume on your computer speakers because this might get loud drag this over to what's called The Voice Combinator we won't get into what that is right now but drag it to both your outputs and the left and right are connected to the left and right out it's basically a very computer that's how we'll visualize it for now anyways so now play a note just press a key on your MIDI keyboard if it's set up or your QWERTY keyboard I'm getting ready in here but no I guess I can't do this little experiment ok so what we'll need is a gate and what the gate does so now we have 2 pitch selected to go out or it sends a command to the oscillator telling the oscillator what pitch to play and then the oscillator plays it through the speakers so now while we tell the oscillator what note to play we don't we haven't yet told it whether or not it should be on or off and when the oscillator is on sound will come out so what we need to do is right-click built in module MIDI in we need to put a gate in there and a gate is basically an on-off signal if you look at info source for MIDI note on and note off events switching the status of a gate output signal so we're going to drag that over to the a or the amplitude input now when we play again make sure the volume on your computer is somewhat low so now you've made basically a sawtooth you made your I mean a really really super basic synthesizer at this point and it's pretty cruddy sounding as you can probably tell but it's it's a start and so now we have to improve upon our synthesizer right now we're going to add a hay and adsr envelope so to make an adsr envelope we will continue with the right click nature of reactor we're gonna right click selected built in module we'll go down to where it says LFO envelope and we'll click on the letter that says adsr which means attack decay sustain release as you can see up here attack decay sustain release so when you're trying out modules get in the habit of looking looking up here again and so that you can maybe get an idea of what what your modules do if you just have no clue that's a good way to find out and so what we're going to be affecting with with this envelope is the volume or the amplitude so in order to do that so you know that the gate controls the amplitude of this oscillator right it tells the note when to turn on and off which basically means it changes the value of the amplitude because the volume is the amplitude so anyway now instead of in order to make this thing work instead of the gate going directly to the sawtooth way the sawtooth oscillator we're going to make it go through the envelope first so we're going to delete this wire just click and hit the wheat or backspace and drag this down to the G is the G and put on the envelope and so token like it'll connect there and now now this output we're gonna put to the amplitude so now the the envelope which is basically I guess a filter is going it's going the gate signal the amplitude signal is going through the gate first its modified by the envelope and is going to the sawtooth way and so now what we need to do is we need to be able to control the attack decay sustain release properties of our synthesizer

  1. !. Thank you for the tutorial. I am enjoying it and I have time to assimilate it as you are speaking.
    I think that gate outputs the midi velocity value (how hard we hit the key) which is what translates to amplitude. Note off is simply velocity = 0. I only share this because it was a confusing issue to me until I read the help files.
    Peace, Myst.

  2. @MrAldoPaolo As a matter of fact, my latest tutorial shows you how to start making a dubstep wobble bass, check it out and tell your friends!
