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.

Help to made a piano midi and cv controller for eurorack (see my comment below).
You can look at https://github.com/elkayem/midi2cv for a complete MIDI to CV implementation with Arduino and cheap DACs. Instead of (or in addition to) receiving MIDI, you'd also need to implement keyscanning and MIDI sending.

Arduino eurorack cv
This project would be a great starting place, it's for a MIDI to CV circuit but it's got all the pieces in place for any random Arduino-based CV project, I'm adapting it to a Raspberry Pi Pico MIDI to CV module and it's working great so far

Stripboard layout for Elkayem's MIDI to CV convertor
I spent some time creating a stripboard layout for Elkayem's excellent midi2cv project. Hopefully this saves someone else a couple of hours ;)

Arduino based midi to cv converter breadboard version
I can't read Japanese but translate works ok-ish on OPs linked page but it mentions: https://github.com/elkayem/midi2cv which is what I am basing mine on - or at least the majority of the hardware that's not the microcontroller.

Finished my power module!
Any reason not to build a MIDI to CV module? Having a MIDI in is pretty handy.

DAC compatibility?
hello, electronic noob here. i was looking at the midi2cv module (https://github.com/elkayem/midi2cv) which uses two mcp4822, and this arduino based cv quantizer (https://youtu.be/op_DhPr2goc) which uses a mcp4726. My question is, can i use in both projects an mcp4725, (https://www.microchip.com/wwwproducts/en/MCP4725) since it has the same resolution and its the only available in my contry

How popular is MIDI to CV?
My starting point for MIDI2CV will probably be this: https://github.com/elkayem/midi2cv - which does seem to have PB provisioned. The fun/creative/potentially frustrating part will be adding a dedicated breath CC channel and matching that up to a symbiotic ADSR/VCA unit.

Synth wars: The story of MIDI (2023)
That makes me wonder how often one runs across a synth that doesn't support running status. I'm working on a MIDI controller myself, and that's a thing I probably ought to enable if I want the lowest latency.
It seems the standard MIDI libraries that Arduino uses don't enable it by default, but it's a configuration option you can turn on, along with a note not to try to use it with USB[1].

Ask HN: What is the most impactful thing you've ever built?
The Arduino MIDI Library [1]. Back in 2009, I learned C++ to build it and control my guitar effects pedals with custom electronics as part of my engineering degree.

Help to made a piano midi and cv controller for eurorack (see my comment below).
Your project can be broken up into a number of subprojects. For keyscanning you don't need additional hardware, just the pins from the ribbon cables going to the arduino's digital pins and ground. Since the keys are just switches (two per key, the time difference between the two switches closing giving the source of velocity), you could start with some examples from the Arduino MIDI library (https://github.com/FortySevenEffects/arduino_midi_library). To test MIDI sending you don't even need to start from the keybed just yet, and if you do, you can start with a single key. Once you've got that part figured out end to end (key press/release generates note on/off events) you can work on iterating through the matrix, CC controls etc. MIDI out can be done in different ways. With a 5 pin DIN plug you'd just need two 220 ohm resistors.

What frequency should a timer interrupt be to receive MIDI messages?
On an Arduino compatible platform the configuration of the baud rate at the bare metal layer is taken care of by the library when you call its begin() method. Looking at the example code included with the library it appears that there are no timer interrupts or anything like that required of you in order to use it. Another thing that jumps out is that the call to read() returns a non-zero value if anything has been received that you should use to predicate whether any further attention needs to be spent on it by your code. You may know this but it wasn't apparent from the loop() { MIDI.read\`() }` example that you gave above.

FastLED run Parallel & Simultan multiple Led Strips
As i have started to combine this with Midi Implementation from FourtySevenEffects lib, i only have done a quick test with two/three strips and did discover follwing issue(s):
-
Reading MIDI stream
Using a library for the midi shield you can register two functions as callbacks. One callback for NoteOn(...) messages and one for NoteOff(...) messages. But thre is much more. In the end the source of truth should always be the docs for the library itself.
