arduino_midi_library VS vgmtrans

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:

1 - There are generic-ish tools to dump/convert the with the notation like VGMTrans, but support for various internal formats/methods/effects/commands is definitely not 100%. I've used that one to dump tracks from many games across various systems and often it works fine, but sometimes an effect/track is missing for one reason or another or sometimes a game's music format simply isn't supported and people need to get hands-on.

A question answered before anybody even asks in the first place: I used VGMTrans to get ahold of all the Midi files. You can get it here: VGMTrans Github page

The two best options, in my experience, would be to use either GBA Mus Riper (yes, it is actually misspelled), or VGMTrans. Both should be able to take a GBA rom as input, and give you both midis, and a matching soundfont to go along with them. Then you can use your music editor of choice to load up said midi, and do whatever you want with it.

Here are the steps I'm following btw. https://github.com/vgmtrans/vgmtrans/wiki/Building-the-Qt-version#vs-noide

You can use VGMTrans to extract the Nintendo files to SF2 files as long as you have a Hotel Dusk ROM.
