Let's Play with Audulus 3 - Part 2

Patrons unanimously asked for more Audulus and I'm happy to provide it! I'm digging this process of developing a patch that will auto-generate a whole ambient album for FAWM! In this video I add a string section, using my take on Karplus-Strong.

Video Description:

This is a continuation of the patch made in my last video, available here: http://discchord.com/blog/2016/2/12/lets-play-with-audulus-3.html

I continue to develop this ambient patch with the addition of some strings using a Karplus-Strong style of synthesis. If you enjoyed this please consider supporting this series by sponsoring them on Patreon: https://www.patreon.com/discchord

Fascinating stuff as always!

However, as lifelong member of the Grand Brotherhood of the Superfluous U I must take offence at your disregard for the wonders of the superfluous U.

Long time reader, first time commenter... Do you think it would be possible to create an emulation of the make noise maths module inside of audulus? I'm sure all your readers have been captivated by the modular movement, but I just can't get my head around that one!

I've considered something along those lines, Brockalicious. However I think a mini-version of the Tiptop Trigger Riot in probability mode will be more useful in this patch, so I'm thinking about doing that in the next one. I'll keep pondering this though and keep your vote in mind!

If I don't do it, you can probably get Mark Body into doing it!

@bob: Among English speaking countries there has been a divide on the issue of superfluous Us, but Canada breaks the tie in favor of the U.S. Conversely Canada breaks the tie in favor of the U.K.'s pronunciation of Z as "zed" so I try to use that too. I think we all agree that Football is the one involving the continuous application of feet upon the titular ball. So the NFL can suck it.

@Brockalicious - Mark Body (lol, Mark Boyd) here from Audulus - yes, doing maths would actually be very easy...if I understood it more!

I'm actually terrible at math myself, and I went to go look at the manual for the module and I couldn't really figure out exactly what it was doing. It someone can lay-speak it for me, I can either make it or describe how you'd go about making it easily.

There is nothing that anyone has asked me "can I clone X" or "can I do X" that I have not been able to do or at least give a roadmap to doing. This is not a testament to my intelligence, but rather a testament to how amazing Audulus itself is.

The only thing that separates me from other people who use Audulus is that I've used it for thousands and thousands of hours.

Thing is, I'm actually not very great with signal electronics/math/sciencey stuff. Many hundreds of those thousands of hours have been spent chasing my tail and doing it the wrong way. Audulus really rewards experimentation and persistence.

In short, if a question begins with "Can Audulus do X," the answer is 99 out of a 100, yes, it can. Come over to the forum.audulus.com and ask your Maths question there - heck, someone made a fractal generator in Audulus, Maths would be a piece of cake.

I love to watch you work. I learned a whole bunch.

I bet I know why you had trouble with your random thingy. Because of anti-aliasing, the oscillator node makes a lousy trigger without a bit of intervening logic to generate a clean pulse. eg., x > 0
Also, the mux node has a built in mod x,8 so it rolls over. When you feed 8 to the sel input, it selects input 1, etc.

@Mark Thanks for getting back to me on that one. Il move the conversation over to the audulus forum and see if anybody has had a go at it... I love the app and can experiment all day but when it comes to structured thinking opposed to ad lib I start to waver...

@Tim Keep up the good work!

let me try to describe MakeNoise's Maths module.

There are four channels of signal processors. Very simple signal processors actually. They attenuvate incoming signals (gain/invert), and if no input signal is patched, each channel acts as a voltage source. There is also a sum, OR, and invert output from all 4 channels.

Channels 1 and 4 have an additional EOR/EOC square wave output which are usually used as trigger or clock signals. These two channels also have a cycle function, which means they are also VCLFO's or audio rate oscillators. They also have trigger inputs so they can act as AD envelopes as well.

Maths module provides addition, substraction, and mixing of CV or audio. It is very simple, but very valuable because we often need simple operations. Just one example: you have a bipolar LFO (-5V to 5V) that you want to apply to an input that only accepts unipolar signals. Patch the LFO to a Maths channel, add 5V, output 0-10V to the destination.

You can imagine how important such a module can be in a patch. In Audulus, well, it may not be that useful because you already have all this maths stuff available. Still, having such a module in Audulus would make a patch easier to build I guess.

I was wondering about how shaping the noise at the front could make things have a more natural decay. With LaPlace, there's that noise burst that you can shape that affects the overall tone. With this, wouldn't the feedback of the delay effectively be your release parameter?

Also, in I've scene "CV" referred to as "Control Value" which makes sense in this domain.

February 20, 2016  | person_outline stub

@JDRaoul: I've had weird results with the aliasing on square waves in other instances, so I think you're probably right. The mod is definitely rolling over... That was a mistake on my part.

@stub: Yeah! Throwing in an envelope or some other mod to play with the Noise Color knob can do lots of interesting swooshing, or decaying, depending on which direction you modulate.

Exactly. And perhaps for another type of sound, putting separate envelopes on both the LP and HP, and on the noise level itself, and then using no sustain and making the decay of the noise burst pretty short, that you could then enter into the more percussive/plucked kinds of tones.

Having some process that makes the noise bursts happen in a more "creaky" and "random" way....

Ok. Sounds like I need to take your project and go in my own way with it.

Thanks for the help getting started!!

Wait, so CV isn't curriculum vitae? No wonder my patches all sound like line noise.

@Tim: I'm pretty sure the American sportball game most famous for its celebration of the Superb Owl is universally agreed to be called handegg. You can trust me, I am an expert in these matters.

@Arrghonaut: I had to look up the Urban Dictionary on that one. Seems appropriate, but sounded Klingon when I read it all as one word. ;)

You've not experienced the NFL rulebook until you have read it in the original Klingon.
