 Hello Oscillator Sync here and welcome to another video in the series where we look at building a patch from scratch for the core monologue So today we're going to be trying to make an organ sound What I say an organ sound I'm thinking of the sort of Hammond organ tone wheel drawbar kind of thing that if you are a much Better keyboardist than me you can do all of your ripping solos on Personally, I don't have that level of skill Let's see if we can make the sound at least so initialize patch As always so a drawbar organ like a Hammond is actually essentially an additive synthesizer where a number of basic waveforms simple waveforms are added together separated or arranged in the harmonic series To build up richer sounds so rather than having a rich sound to begin with like a sawtooth wave What we do instead is we layer Or basic waveforms like a triangle wave, but at different intervals to build up that richer sound now the monologue is it's a Subtractive sense with only two VCOs So we're gonna have to pull a couple of tricks here to really get away with this sound, but we can do it so We'll start by setting the VCO to the triangle I'm gonna bring in VCO to We also set its triangle and we're gonna put it somewhere else in the harmonic series So I'm gonna put it up an octave and then also up around a fifth Or thereabouts, okay, so now we've got this kind of sound going on It's not exactly an organ sound But maybe like a very very basic church organ thing going on. Let's see if we can make it better So what I'm gonna do is I'm gonna switch VCO to into ring mod mode So this is going to ring modulate VCO to you with or rather have VCO one ring modulate the VCO two Which is going to introduce additional harmonics It's time to sound a bit more organ-y. The other thing that it will do is if the oscillators are out of tune Just slightly it's going to emphasize that beating that might also give us a bit more of a realistic organ sound It's time to emphasize those higher harmonics as well Okay, so that's two oscillators and we're abusing ring mods to get a bit more harmonic interest, but I could do with maybe one more Oscillator so we're gonna use the trick that I showed in one of my other videos where we're going to use the filter as an additional Oscillator by cranking its resonance Okay, so we've got an additional sort of harmonic sound in there, but at the moment It's gonna stay still But we really want it to move with the keyboard so we're going to go into edit mode go up to the fourth Light here. We're gonna click until we get to cut off key track Turn that on to a hundred percent and what that's going to do is it's going to automatically move the cutoff knob For us as we move our as we play different keys, so that's basically gonna move this third oscillator around Okay, so this is starting to sound a bit more like an organ this it's already also sounding hopefully quite cool in the lower registers Nice okay, so there are a couple of things that we can do to make this a little bit more convincing One of the main thing that's missing for me at the start of the sound at the moment is that there's no click if you listen to a lot of Hammond organ sounds as this very distinct click at the start of each note and we're missing that the moment So what we're going to do is we're going to go to our envelope generator I'm going to aim at pitch to kind of works aiming at pitch as well overall But I'm having experimented I slightly prefer it on pitch to We're going to send a bunch of intensity over to there So if we had our envelope generator by the way, we'll have it on gate and envelope rather than any of the modes So if if we send a bunch of pitch to Sorry a bunch of intensity to pitch to at the moment with a long decay We get space sounds, but it's not very organi if we bring this decay right the way down We can get this click at the start of the note. So this is without it This is it with it. Okay, so that's helping as far as I'm concerned Okay, so what else can we do? So one thing that you tend to get with your ear big organ solos is that we've got a bit of overdrive on it So I'm just going to bring up the drive control until Start to hear the fizz I'm just going to bring it back to the fizz Okay, so what else can we do? Well, one of the things I've discovered almost by accident is that if we adjust the shape control on VCO2 it's almost like bringing in additional drawbars That's because the shape control on the triangle wave essentially performs wave folding Which eventually gives us octave frequency doubling essentially so we get a bunch of additional harmonics happening so we can do something like this So that's interesting so that might well be a candidate for what we put on our modulation lever because we don't really want Pitch bend on there. So that's one thing we can look at. The other thing that's kind of missing from the organ sound At the moment is We kind of want that Leslie thing happening Now we've got nothing here that's going to properly approximate a Leslie speaker, but If we send a bunch of LFO Sort of on slow-mo triangle over to the shape of the oscillators we can Begin to get some of that kind of Leslie vibe. So I think That's what I'm going to put on my modulation lever because then I can bring it in and out. So I'll turn the intensity back down to zero Sounds quite boring without it now if we're going to edit mode and we'll go over to the second Light which is our slider sign. I'm going to go across until I see my LFO intensity. There we go And that means that I can bring that Leslie effect in and out And I think we've got a pretty passable kind of organ sound now I hope you enjoy that guys I hope you found it interesting and informative and all that stuff if you did please hit those thumbs Give it the like and also make sure you've subscribed to the channel So that you don't miss out on any upcoming videos on the core monologue and synthesis in general Thank you again for watching everyone See you soon
