Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Manufacturing somewhat novel MIDI controller
You are about to bite off a lot. Ignore all the other advice in this thread, I do this for a living.
You have some software experience, this is good. Assuming you have embedded software experience (which is essential for what you are doing and not at all like web programming) you have a foothold to finish this project without going completely insane.
Hardware is a completely different beast. With software everything happens in your head and when you get stuck you can usually think your way out of it. With hardware, you really do need to learn to do things meticulously and step by step. There are many things that can go wrong. You will learn a lot on this journey.
Don't be afraid to ask for help. Finding a hardware community will be essential to do this as you learn the skills you need. You're going to make a lot of mistakes, best to go in embracing it
A good place to start is to join an open source community for MIDI. Two off the top of my head is http://www.ucapps.de/ for MIDI specific hardware and https://www.electro-smith.com/daisy
A large amount of the work you will find yourself doing at the beginning is just figuring out where and who to ask questions about things like the keybed and other hardware issues. None of this is terribly 'hard' but none of it is easy. Most of it comes from experience.
It is almost always best to use someone else's product when you are designing your first. Roger Linn (https://www.rogerlinndesign.com/) gave me some fantastic advice a couple years ago when I was trying to design switch caps: "Do you want to be a company that designs switch caps or one that designs synthesizers?" and that stuck. I don't want to design switch caps, so I bought them off the shelf, contracted someone to design my own, and moved on.
So to that end... just buy a couple keybeds from Fatar or someone else, or just grab a synth you already have or buy one off ebay and harvest the keybed from that (often times much cheaper than buying direct!)
Don't be afraid to spend money on tools. If you find something difficult, like soldering, I have not once regretted spending money on better tools. They grow with you and save you hundreds if not thousands of hours of unnecessary frustration. When you know you need a tool, find a way to get it.
Maybe I should make a blog post about this... hmm
Hope that helps!
- Is there a programmable module for audio (like EuroPi but w/ bipolar output)?

how to make an “experimenter”?
Check out Daisy DSP from ElectroSmith. They have an entire platform you can build your own synth upon. Many new EuroRack modules being released over the last ~1.5 years are built upon the Daisy SDK.

Rendering audio blocks in a digital oscillator (hardware)?
For an excellent implementation of C++ embedded audio DSP, checkout the DaisySP project and associated hardware. The libDaisy audio drivers abstract this block processing well.

A Chord Synthesizer From Another Dimension
There is a github page for this that has downloadable firmware and a link to the firmware programmer which suggests that it’s running on a Daisy. Although it would be ethically super questionable at best, it probably wouldn’t be that hard to reverse engineer.

Something between Rpi and Rpi Pico?
I have just seen https://github.com/dwhinham/mt32-pi but it doesn't seem as easy to play with and well-documented as the other software I've used.

Cool system. I'd see if you can get a hold of a Roland MT-32 type synth. If your sound card has a daughterboard connector (it does, top right corner) you can get a Serdaco Wavetable board which would let you have generalMIDI output. An external MT-32 or a mt32-pi will also greatly improve your music output.

Roland MT-32 Emulation
Regardless the best option is a MT32-pi solution. https://github.com/dwhinham/mt32-pi/wiki/Custom-hardware

Sound canvas / tone generator
I think MT-32 and SC-55, at least, are wildly overpriced for what they are from a music perspective, thanks to the retro gaming bubble. If you want to mess around with one, I would recommend checking out mt32-pi. In addition to the extremely limited MT-32 sound palette, it can also load soundfonts, which really opens things up a lot.

Raspberry Pi in synths?
Check out Mini-Dexed and MT32-Pi. I use both and they're great. They are built on the bare-metal "circle" platform, so they don't run on top of linux (so no faffing about with JACK routing, etc.).
- Ask HN: What cool projects do you suggest I build with a Raspberry Pi 2W
-
My take on the MiniDexed - first synth-diy project completed
its a CJMCU 5102 DAC Board, which is one of the supported soundcards. You can use the internal headphone jack of the Pi as well, however it only supports 12bit PWM audio there, which is usable but has a lot of artifacts and I would not recommend therefore
-
I'm not sure where else to post this but I need a bit of help.
You can turn a Raspberry Pi into a Yamaha DX7 using MiniDexed or a Roland MT-32 using mt32-pi (which also loads soundfonts via FluidSynth). I use both of these regularly. They're great. Both work with USB MIDI controllers with no additional hardware required and boot headlessly in a few seconds to work like a true instrument.
