Musical Chord Progression Arpeggiator (outpan.com)

This is straight up lifted from this demo - https://codepen.io/jakealbaugh/pen/qNrZyw (previous HN convo - https://news.ycombinator.com/item?id=13273901)

Actually, this whole site is pretty strange. Lots of code and open source projects just kinda copied into an app library.


This explains it:

> Developers Earn Money On Outpan!

> How It Works

> Once you choose to monetize your apps we'll take care of everything. Outpan will use sophisticated ads with optimized placements on your apps to autmatically generate revenue for you.

From https://www.outpan.com/developers

So basically this is monetization spam


The website claims it's a monetization method for projects: https://www.outpan.com/developers

Not trying to be overly cynical, but I don't know how true that is. It's still possible this was lifted without the creator's consent.


If you click on the 'i' at the bottom right it shows this dialogue:

"Musical Chord Progression Arpeggiator by LetsPlayAGame A quick way to sketch out musical chord progressions.

So that looks to be mostly in the clear, but it would be nice to know if the uploader really is the creator.


I'm a co-creator of Outpan. You are correct that there are lots of open source projects on Outpan, because we offer financial incentives for people to host apps on Outpan (the incentive is similar to Youtube).

That said, there are also many proprietary apps and games on Outpan too and if an app is posted by someone who doesn't have the rights to do so, it is removed and the user is banned; then again with open source, as long as the license is valid and the terms followed properly, we can't really remove them. In the case of this particular app, it was under MIT license as mentioned in the about section. I understand that the 'About' section of the app may not be super clear causing confusion, we'll try to make it more visible.


That very elegantly sidesteps the question: is this app uploaded by you or by the original author or by someone else entirely?


Definitely cheeky. All work on CodePen is by default MIT. Looking at the first demo on the homepage, the act name is “cpmirror”, so fair to say people looking to jump on making money from others work is a big incentive... but also, what’s new I guess :(


It was uploaded by someone else entirely, but we did check to make sure the license is valid.


Don't you find it odd - to say the least - that you would offer to financially reward someone who did not author the project?


Not really, since the original software is released under an open source license, in this case the MIT license which allows for monetization as long as the terms are followed. If the poster hadn't followed the terms we wouldn't be ok with it.

This is common on mobile app stores too: for example there are many variations of the ZXing barcode app which all follow the terms of the open source license, some are even paid apps.

Another example would be cloud services offering commercial products based on mysql, redis, elastic...


You're not breaking any contracts or laws, but posting a clone of a previously discussed project with ads tacked on by a third party is worthless spam. I flagged the link and I suggest others do the same.

Not the first spam, one of which was even titled Show HN:

https://news.ycombinator.com/submitted?id=ent101


I didn't know this project was posted before; that's my fault and I apologize for it. I have contacted the mods to remove the post if they feel so. That said, I have never tried to spam HN, just posted links from our site which I thought the community might like, I'm sorry if it came across as spammy.


Funnily enough, you said the exact same thing the last time you were called out for it: https://news.ycombinator.com/item?id=21108977, but apparently didn't feel the need to stop posting such submissions?


Sneaky... good find.


Who is to say the poster isn't you, after all you are submitting the link here too to draw traffic to it. I don't like the smell of this even if it may be following the letter of the law. You are essentially monetizing other people's work without even notifying the original authors so they can claim their own work.


Your beef is with open source licenses.


It's really not.

As a community, do we want to be sending eyeballs to the original source, or a monetized copy?

OP is free to do what he or she is doing, we are free to block it as spam or link to the original source.


I don't know man... I tend to agree with @recursive here. I think some of you guys aren't treating the poster fairly.

I can see why this would get some people fired up. It definitely feels a little gross presented in this manner. But... it IS MIT liscense. Nobody made the author release it this way.

He could have easily released the demo on his own website and not provided the code "without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies".

I'm glad people pointed out the original author, I just went and browsed his codepen page. But we have to assume he is OK with people coyping or even selling the code assuming the license is not breached.

I agree the site should be banned.


I'm not complaining about the existence of Outpan, or trying to mount some defense of the original author.

I'm saying that links to this kind of aggregator have no place on Hacker News. What benefit is it to the community to have the authorship hidden and ads added?

Talking about licensing is orthogonal to my point. Blogspam is totally legal and not accepted here. This is no different.


That's a beautiful tool. I should collect and organize all my music links from the past six months or so there are all kinds of very nice tools out there.

For instance this one:

Thank you, looks great and it's open source too! This is another favorite of mine: https://grunfy.com/scaler.html


Great work, Jake Albaugh. Needs one critical revision, though: I, V, VI, IV in major MUST NOT be allowed!

Pretty neat. It'd be nice to be able to choose more chords. For instance with some inversions the voice leading can be improved. Also it'd allow for using secondary dominant and other chords with non-scale notes.


Pretty cool, though it seems there are many common progressions that it can't make, as it forces you to choose a single scale for everything (the block titled "mode" should really say "scale"). For example, minor progressions rarely stick to a single scale like this tool requires.

With that said, you can still make a wealth of cool progressions in a single scale, and the limitation is interesting to work with.


Perhaps "scale" should be its own block. The first 7 modes listed are in fact modes of the same scale so the name is fitting. But "Melodic" and "Harmonic" are their own scales, each with a corresponding set of 7 modes.

It would be cool to select modes of those scales as well. For example Phrygian Dominant (mode of Harmonic minor) is very common in a lot of metal music, some classical, Eastern European, etc.

As an aside, the line visual for the arpeggio styles is really cool! It would be neat to select different arpeggios for each chord and see the whole progression drawn out as a line.


> it forces you to choose a single scale for everything

That confused me as well, but I think what the author meant was that the scale applies to the I. If, for instance, you enter IV III II I Ionian, you get the Lydian-Phrygian-Dorian-Ionian you'd expect (at least as far as I hear it).


I'm launching an IDE for music composition soon http://ngrid.io


Everything on there sounds pretty interesting, especially if it can deliver the goods :) I signed up to be notified, but is there a rough idea of when you’re planning to launch?
