    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!

  • osci-render

  • 4klang

    Official 4klang repository

    Project mention: help packing sound in <4k | /r/Demoscene | 2023-05-12

    I had a deeper look at 4klang, it looks like it's not really taking care of sound output, it's "only" creating the sounds and filling a buffer (I might be wrong, that level of assembly is soooooo over my head. still damn interesting to read, tho)

  • 64klang

    Official 64klang repository

    Project mention: help packing sound in <4k | /r/Demoscene | 2023-05-12

    Gopher also made 64klang, and in the examples here they're using mmsystem to push samples to the soundcard, so I'd be inclined to think that's a pretty good way to do it (if not the best way)

  • esp32_basic_synth

    ESP32 based simple synthesizer project

  • Polaron

  • KnobKraft-orm

    Project mention: Opensource Patch Librarians? | /r/synthesizers | 2023-11-04

    Consulting the oracle Google I did find one app Knobkraft but it just doesn't want to work correctly for me on my Mac. It complains about not finding python3.10 yet I know it's installed and have it in the environment path.
