Exploring the Polynomial Modulator in Bitwig Studio
Tutorial | Jul 06, 2021
In this video, I showed how to use the polynomial modulator inside Bitwig Studio to create interesting distortion, wave shapes and overtones. I demonstrated how to use a DC offset device with the modulator, and how to modulate the X parameter with an audio rate modulator. I also showed how to use an LFO, as well as a stereo split to create unique sounds. Finally, I shared some tips and advice on creating presets, and how to save the new device for future use.

[00:00.000] Welcome back to another video today. It's all about the polynome modulator inside Bitwig studio
[00:05.440] It's not my most used modulator at all and you probably know this when you watch my streams
[00:12.720] But nonetheless, it's an interesting modulator and it's versatile and you can do some interesting stuff at it
[00:18.840] And I want to show you some examples for inspiration, you know, and to maybe lead you to new paths to sound design or for sound design in Bitwig studio
[00:29.160] So let's switch over here to Bitwig
[00:35.080] So yeah, we have a completely empty project here. Maybe let's load a pick drum
[00:41.960] Paint a new small pattern
[00:47.320] So we have this running here, so it's a kick drum
[00:52.720] Pretty simple pretty easy
[00:56.080] Yeah, it's recalling nice
[00:58.080] So now that we have this we can insert you may be a chain device, which is just a container with nothing in it
[01:06.080] But then we insert here a tool device and I remove this here because it's my default modulator on the tool
[01:12.520] So we have now a tool in here and we bring the volume down to minus infinity, which just moves the sound
[01:19.640] So we can't hear anything
[01:21.640] So now we insert your DC offset device and when we use a DC offset device, we can just modulate the audio stream or insert values or voltage
[01:33.200] I don't know how you want to call it
[01:36.880] Or we can change the waveform at all. So when we hook up here and
[01:42.280] Oscillator or oscilloscope
[01:44.280] You can see everything that we move here with the DC offset device. You can see in the oscilloscope. Maybe you can also hear something
[01:52.640] Happening on your on your speakers or your headphones
[01:57.040] Because I'm modulating your membrane of the speaker directly with this here, right?
[02:02.040] So you can move the speaker or the membrane in and out or in and out. So like this
[02:07.360] So that's okay, but now we just add here an audio rate modulator, which kind of analyzes the audio signal coming into the chain here into this
[02:19.680] Modulator, you can see the waveform on here and we
[02:25.680] Analyze or grab the mono channel here because it's probably a mono sound. That's the e-kick
[02:31.720] But you have to be aware of that that it's only covering one channel at a time
[02:35.560] So we
[02:37.840] Selecting on the mono channel and then we modulating DC offset device which gets us
[02:44.480] Just the sound as before
[02:48.520] like this and
[02:51.520] Now we answered here insert here a polynomial modulator and
[02:55.960] When we dial in here a certain numbers for instance here zero
[03:00.120] Zero zero zero. Okay, so now we dial in one. We have a perfect nice
[03:06.160] linear
[03:08.760] trans trans
[03:11.920] Transition no, no, it's not so interesting transform function
[03:15.800] Where we get the same signal out as we are sending in so now we modulating at the X
[03:21.600] Parameter and then instead with this one we modulate. We don't modulate the DC offset device
[03:29.560] We only modulating here from the polynomial on the X parameter and then we modulating with this one here the DC offset
[03:36.240] Device which now gets us the same sound as before
[03:40.680] But now we can see here to kick drum
[03:44.280] As values on this line and now we can transform this line in
[03:49.280] In different ways
[03:58.520] So it's it's more like a it's kind of a wave shaper
[04:07.920] I
[04:11.200] Think if when you put in here one and instead of one you go to minus one you have the inverted line here
[04:18.960] And you get a a polarity flip if I'm not wrong
[04:32.560] Well, maybe we
[04:35.440] We dot the gate us here into a chain device and then we flip this year around so it should be quiet now
[04:43.000] It's completely quiet. So it's a polarity flip
[04:45.440] Yeah, so you can flip the polarity with this if you want
[04:53.200] Let's see. Let's put this out here again
[04:56.640] um
[04:58.640] And you can change the waveform or you can you can wave shape basically your sound what you can also do is to
[05:05.920] How do you rate and modulate some of these parameters here which gets interesting sounds? So you can create some overtones to
[05:22.640] Simple sounds or Sine-Wave he sounds if you want. It's a nice way of adding distortion or unique distortion
[05:30.880] But just more important to have some devices that are unique to your to your own sound
[05:36.880] Or at least that's what most people search for write your own unique sound
[05:41.280] So you can design your own wave shaper or come up with some nice patchings for distorting the sound also interesting instead of using here the same
[05:53.120] Audio rate modulator for modulating all these parameters here. You can also switch for a go for
[05:59.520] um LFO
[06:02.480] Which has also here audio rate
[06:06.240] Speeds kilohertz for instance
[06:08.240] And then modulates on parameters here
[06:29.440] Nice huh
[06:31.440] I can also go for a pitch
[06:33.440] Pitch of the current node and because the e-kick is pitch agnostic and it doesn't care which kind of
[06:41.280] Um note you are you you are using on on the piano roll
[06:46.320] Um, but this one does now here this
[06:49.680] This modulator modulator this LFO
[06:52.480] Uh, so we changed this here to pitch and now we can
[06:55.600] Oops can change some of the keys
[06:57.600] I
[07:00.800] And can get kind of different modulations for different
[07:06.240] kick drums
[07:12.560] You can change the overtones to some of your kicks by changing the pitch because now this LFO is um
[07:21.440] Yeah, changing the modulation speed um with the notes. Okay, so that's pretty fine
[07:26.640] The e-kick is a mono um, so we have basically only one channel. We we need to care for
[07:33.600] But what if we use actually some stereo sounds? So this is also no problem
[07:39.040] Can you maybe exchange the e-kick for a policeman?
[07:44.080] Dial in your unison. So we have a nice stereo spread
[07:48.800] So we kind of create a
[07:50.800] It had sound or something like this. I don't know. Let me turn this up here. Maybe we go
[08:00.400] Um, dial in here some
[08:05.360] Some sounds
[08:07.360] It's a bit longer
[08:17.360] Oh
[08:36.880] Okay, so now that we have this you can hear
[08:40.000] Um, we get only a mono sound out of this distortion device or
[08:43.680] Oh, out of this um, yeah, wave shape, but we created when we um
[08:49.200] Remove this you can instantly hear how how the signal becomes wider
[09:02.720] Okay, but now to to make the stereo or the distortion device stereo um
[09:08.960] We just duplicate the modulators here
[09:13.680] Um, like this and for the first one we use the left channel for the
[09:18.880] For this one we use the right channel and then we put this here the DC offset device into the stereo split
[09:27.280] And this goes into the left channel here. So we modulate here the left
[09:32.000] um
[09:33.520] With this uh thing here and then we need of course also twice the um
[09:41.440] polynoms. So this one modulates this and
[09:46.000] This one modulates this one here
[09:50.080] Like this and then we modulate here the the right one. This one is modulating this one
[09:55.840] We put this in here
[09:57.840] So
[10:02.480] This one is modulating this device. Let's see
[10:13.760] So this is the right channel is the this the right channel and there's the left channel here
[10:20.000] Okay, so now we have it finally
[10:22.000] And then we have just one LFO modulating both of these polynoms, right
[10:28.640] So now let's try this
[10:30.640] Oh
[10:46.000] Nice
[10:49.520] I've also got here too much for you, which is the most pitch
[10:55.200] Or one octave higher
[10:57.200] Oh
[11:00.400] Now we get some overtones on um digital distortion on top
[11:05.360] Can be interesting when you put the reverb on on the end so we get more overtones
[11:09.440] Maybe modulate your more of these
[11:29.360] But we also interesting device instead of in front of this reverb we can put this here in the tank FX
[11:35.280] So it would be also interesting
[11:39.280] Oh
[11:41.280] So
[12:01.280] So you have some distortion or device in the tank FX that adds some overtones to your sound in the pre reverb stage
[12:18.720] Which can be nice
[12:20.720] Maybe not always what you want, but you have the option and you have the possibility to do it
[12:26.560] I'm just here to inspire you on trying to inspire you
[12:29.680] So
[12:31.680] Okay, so this is also possible we need basically for stereo version of this device just two
[12:38.240] polynoms we also need to
[12:40.240] I'll do rate modulating modulators and then
[12:43.760] You feed everything into a DC offset device inside
[12:48.160] Stereo split for the left and the right channel
[12:51.680] Pretty much an easy setup you can do this every time you want to use some kind of device like this
[12:57.280] But you can also of course
[13:00.640] Save yourself some time and create some
[13:04.240] Yes, I'm pretty sad yeah, maybe modulator the intensity with this call it
[13:08.720] intensity
[13:10.720] And then you have a device with just a nice macro you can use dial in the effect maybe also at your preset page
[13:18.960] Bring in the mix knob and intensity
[13:21.360] and then hide all the modulators and you have a new
[13:27.440] um unique
[13:30.240] um wave shaper
[13:34.000] Right, and then you can save it as a preset
[13:41.280] And recall it every time you need it
[13:46.080] Distortion there's no distortion category
[13:48.560] um
[13:51.280] I'm called modulation
[13:53.280] And save it so now we have a nice new device for bitwik studio we can use every time we need it
[14:10.800] So that's just one use case of course of the polynom inside bitwik studio, but for me it's probably the most interesting
[14:17.280] um
[14:18.400] Set up to use it with
[14:20.240] uh audio audio rate speeds to create overtones and nice harmonics distortion and so on
[14:26.640] and
[14:27.520] Yeah, you can of course use this with much much lower frequencies to change the modulation
[14:32.880] Um or some modulation values over time in a nice curvy way
[14:38.320] Um, so it's an interesting modulator
[14:40.880] Um, I probably use it more often than in the future try out some new
[14:45.440] um patches
[14:47.120] Maybe I release some presets in the future. I don't know
[14:50.400] But for this video, I want to give you some inspiration some tips
[14:53.600] What you can do with it. Maybe try it out for yourself
[14:55.840] Maybe you come up with much much better ideas than I am in this short video
