arduino_midi_library VS eap_proxy

take a look here

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.

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.

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.

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):

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.

Here’s a library that might work.

Solution from GitHub here:

The inspiration is the EAP Proxy that I used to bypass the AT&T router and connect my router to the AT&T fiber, before I learned about the vulnerability that allowed me to copy the 802.1x certificate from the AT&T router to my router. https://github.com/jaysoffian/eap_proxy

I use an EAP proxy to put my router in front of theirs and got a %20 speed improvement.

With my wife, I built two kids both in college now. That's definitely the most impactful.

In the online world, I've contributed bits and pieces to open-source here and there as far back as the late 90s. I think my first contribution was to the shadow package, but I've contributed here and there to Apache, Radius, random packages that I use that I discover bugs in, etc.

A python script I wrote to allow folks to bypass AT&T's residential gateway was used by more people than I ever expected:

There are forum threads about people rooting these routers to try and extract the certificate/private keys from their provided router, which worked for a limited time with certain router models. For now, the most popular way to do it is with a tool like this: https://github.com/jaysoffian/eap_proxy

If you use a Ubiquiti router, then another method to bypass your ATT router is called EAP Proxy.

WEEELLLLLL, there is a way to get into a true bridge mode on some ATT fiber plans/service by using something like EAP-Proxy: https://github.com/jaysoffian/eap_proxy

If you're up for a more complex setup, it is possible to put your home network on AT&T Fiber without going through their boarder gateway. I've had luck using https://github.com/jaysoffian/eap_proxy to bypass the boarder gateway for traffic flows.
