 Hey! I'm Anfa. Welcome to my Trap Drums mini-series. In this video I'm going to synthesize a kick bass or an 808, if you will, from scratch. You'll learn how that sound works, so hopefully you can put your own spin on it. By the end of this mini-series we'll end up with this. As you can see there's a kick bass, a snare and a hi-hat. I'll show you how to synthesize all of that with just one plugin. I'm going to use the Zenfusion synthesizer, my open-source weapon of choice for sound synthesis and Ardour, my favorite open-source DW. Still you should be able to more or less follow this series with any decently capable synthesizer plugin and at all. If you'd like to learn basics of Zenfusion this mini-series should also give you a head start. And lastly you can download the MIDI files, Zenfusion presets and the whole Ardour session to play around with on your own. The link is in the video description. Enough talking! Let's get synthesizing! I've prepared myself a short MIDI loop. For now it's just the in-it patch of Zenfusion FX or Zenfusion which is just a sine wave. So let's open up the interface. Let's go to add synth and here let's first pitch shift this two octaves down. That's more like it. Now in the amplitude I'm going to rise it to make the whole thing louder. Now the amplitude should slowly decay so let's use this envelope. I'm gonna move the sustain all the way down and extend the decay time. Maybe a bit shorter. That's about right. Now we need to add a pitch envelope to give it that kick character. So I'm going to use this pitch envelope. Now tuning the envelope is a very important step so I'm going to spend some time on this. Let's go to the free mode where I can freely move all the points, add new points and just tweak the envelope as I want it. I think that sounds nice. Okay now I want to add a little bit more punch to the sound. So let's go to the second voice. Let's enable it and it's just another sine wave but let's turn it down. You see I'm just in the voice tab turning down just the voice not the whole instrument. Now let's go to the modulation tab and change it from the oscillator or sound to white noise. Now I can go to voice, amplitude, envelope. Let's activate it and we can shorten the noise part itself. I'm gonna also reduce the release time so we can easier see the whole function here in this window. And that's the base of our kick bass. Now let's go to effects. I want to add some distortion. Let's go to part insertion and insert a distortion. It's a bit too much. Let's lower the drive a bit. Also I want to move up the Lopez filter so it is open. It doesn't cut off any high frequencies. I'm also going to lower the amount a bit. So it's parallel. This is basically the dry wet control because for example give it more distortion but mix it back with less amount. I like that. And here's our 808 like kick bass sound. In the next video I'll show you how to synthesize this sweet snare. See ya!
