Show HN: Randomly generated metal riffs using Web Audio API and React

Along these lines, someone posted a neat Web Audio driven chord progression arpeggiator yesterday: <a href="http:&#x2F;&#x2F;codepen.io&#x2F;jakealbaugh&#x2F;full&#x2F;qNrZyw&#x2F;" rel="nofollow">http:&#x2F;&#x2F;codepen.io&#x2F;jakealbaugh&#x2F;full&#x2F;qNrZyw&#x2F;</a><p>Comments: <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;web_design&#x2F;comments&#x2F;4qmgxo&#x2F;musical_chord_progression_arpeggiator&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;web_design&#x2F;comments&#x2F;4qmgxo&#x2F;musical_...</a>

Excellent work ! I saw many random music generators, and this might be the best. I showed it to a coworker playing in a metal band, he&#x27;s stunned ! It sounds really good.

Amazing job :) I&#x27;d love to see it with deephouse or techno sounds. It&#x27;s so tempting to fork the repo.<p>Here&#x27;s my madness: <a href="http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;opYJd9" rel="nofollow">http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;opYJd9</a>

I&#x27;m impressed. Congrats! I would love to be able to generate a 3 minutes long tune with this<p>On Android&#x27;s Chrome the URL shown under &quot;Share this URL:&quot; weirdly glitches the selection sliders.<p>Love the beginning of <a href="http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;OkR9gw" rel="nofollow">http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;OkR9gw</a> TUMMM TUMDUM<p>EDIT : You should add a &quot;Download&quot; option because man do I want that as a ringtone

Can you make the settings link more prominent. I left the page before even noticing it. Came back because of the comments.

Messing around in the settings feels like telling a talented child what to play - it can technically play anything but isn&#x27;t sure what to go for! <a href="http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;gN3Ao9" rel="nofollow">http:&#x2F;&#x2F;djen.co&#x2F;#share&#x2F;gN3Ao9</a>

This is an amazing piece of work! Would love to know a bit more about the implementation.<p>And I really wasn&#x27;t expecting the settings to be such a goldmine.

Hehe!! I love this. Did you record the samples or did you get them from somewhere? The overall all audio and production quality is actually top-notch, with the exception of clipping the samples on rapid cuts. Great work!

This is crazy, man ! Fantastic work !<p>I generate a riff and continue working, then I go and generate another one ...<p>Future of music right here.

Really interesting project. Can you give a brief description of the algorithm?<p>Also, would it be possible to export MIDI, or some other format where you could drop in your own samples?

Now we need to plug Compressorhead to this.<p><a href="https:&#x2F;&#x2F;compressorhead.rocks" rel="nofollow">https:&#x2F;&#x2F;compressorhead.rocks</a>

Wicked fun and glad to get a chance to test it out. Excellent results with tweaking parameters, at least to my ears. Functional and appealing, well for those into this sort of heavy chug style (djent), which I get a kick out of most of the time. Spiffy!

I love it! The instrument selection is good. It generates some brutal riffs with catchy rhythms. As a guitarist, I think this tool is great for finding inspiration and maybe breaking out of a creativity rut.

This is so good. Why did u get djen.co instead of djent.co?

The &quot;safari bug&quot; error message appears for me even though I&#x27;m using Google Chrome, not Safari, on my ipad. Is that intentional?

I&#x27;m a electric guitar player myself, and that&#x27;s amazing.<p>The source code is MIT (<a href="https:&#x2F;&#x2F;github.com&#x2F;RossMcMillan92&#x2F;djent" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;RossMcMillan92&#x2F;djent</a>) but I wonder if the same applies to the audio samples.

Very well done. The music was addictively responsive to even the smallest settings change.

I have absolute no idea what I&#x27;m doing, but damn I feel like a rock star! Kudos!

Amazing. Add basic beat and transitions and i could listen to it all day

awesome stuff, i love it, also i forked it but cant share the url. google api changed but nothing happens when i hit share riff. where are the files saved? keep up the awesome work!

Can we get some european power metal style generators in place? :P

Tried three times and like one. Pretty good. Sounds like Helmet

Nice! I read a little bit about the Web Audio API but haven&#x27;t gotten a chance to try anything with it yet, this sounds awesome.

Ha, I love this. Love the name too, great job

Awesome tool, and great URL to boot :)

This is insanely rad. Great job.

Oh how I love this.

The first web app that blows my knees out!<p>Excellent work!

This is hilariously good. Great work

Amazing!

Sounds great. Now somebody needs to train a deep learning network to recognise the good riffs and it&#x27;s done, heavy metal is cracked.
