Limiting this to work only with folks who have MIDI keyboards attached to their machines probably cuts your audience down by 99.9999%. Especially here on hacker news.
I think you’re going to find it tough going to get any real feedback with that requirement. You might find better luck launching in a community of folks who are more likely to meet your hardware requirements.
I made an app to help learn chords and keys too: https://apps.apple.com/us/app/bloopkeys/id6689494178
Mine doesn't require MIDI (although it supports MIDI out as an option), but I can see why you went with that for yours.
Some notes/thoughts: 1. It didn't work on my iPhone (either with Firefox or Safari). 2. A helpful sentence or two would be useful. For example, it wasn't obvious that what you were looking for was midi in and not midi out. 3. Ignore the folks on here talking about monetization (it won't compete with something like Melodics). You made a fun little thing and that's great.
I got it working by plugging my Yamaha P-515 MacBook Pro into my computer. The ergonomics of playing the piano while viewing on a laptop were awkward.
As to the game, well, it doesn’t do much yet. Just prompting me to play some chords. But it’s a start.
Congrats on launching, and good luck with the next steps.
As you mentioned, this is a first step and the main goal is to help build muscle memory for common progressions. And also how chords solve into each other, not just learning the chords themselves.
With the great feedback I got here, I am planning to improve it so that more people can enjoy it.

I built SonicStandard because my music recommendations started to feel weirdly “same-y.” Great production, polished playlists… but fewer surprises. And I was tired of those fully AI generated musics which all sounds like each other. And I kept running into great releases only because a friend happened to DM me a link. So once a week we publish a short “issue” of hand‑picked tracks across genres, languages, and scenes. The goal is simple: a small set of picks that feel intentional, with just enough context to tell you why it’s there.
A few details, since this is HN:
It’s free to browse you can explore the weekly issues directly on the site.
There’s an optional weekly email if you want the issue link delivered.
I’m not anti‑AI: I even in this project used AI to score new releases how those are AI generated! but the final selection is human listening + judgement.
I’d love feedback on:
whether the site makes it easy to explore each issue
anything you’d change to make it a thing you’d actually come back to weekly

I’ll stick around in the comments and answer everything (including the curation process).
