Show HN: I created instruments for people who have no idea how to play one (jamfetti.boondoggle.studio)

I designed Jamfetti so that anyone could jam out and make music even if they have no experience. It works by doing the hard part for you. Every note you play is shifted imperceptibly to land on beat. Every note also comes from the same scale so that they sound great together.

You can pair any instrument with a number of cool 3d visualizers. Let me know what your favorite pairs of genre and visualizers are!

Nice job. The notes quantized to the beats is similar to how arpeggiators work, or arranger keyboards such as when you change chord progressions.

If you like experimental musical visualization stuff, you might also check out electroplankton for the Nintendo DS. It's an oldie but a classic.

Yeah, very cool! What is making the sounds? Web audio API/tone.js? Samples?

this is really cool. Are you an actual developer? the studio seems to be owned by non-tech folks so if not, pretty cool...

Hey, I am the developer. Our studio also make the Hemingway Editor, but this is one of our more fun projects.

Cool! The mouse mode was great! The keys, of course, still required alittle skill to sound melodious XD I love your visualizations. What are you using for your 3D? three.js?

Very cool. Did you have to pick a specific set of notes that work with each other in any order whatsoever? And if so are there other such combinations of notes? or is it actually just quantization that makes it sound good, and any set of notes that are played confidently and on-beat will always sound good?

My kids love this! Makes me think this could work as a hardware for young kids

Hi! I know absolutely nothing about music, but I played with Jamfetti for over an hour. It's so well made.

I wanted to keep playing, so here's an idea: what if I could loop what I just played, and see what I pressed on the screen (like a trail of the notes)? Then I could layer melodies and keep building on them.

Thanks for making this.
