How to open MIDI-file and get events in a list?
#1
I am planning to make a program that converts a midi file to a readable piano-roll editor. I worked on the design for like more than a year(!) and after a lot of drawing by hand, I want to just make it...
I want the program to open a midi file and render every line for me. I am not very experienced in programming but I already made a lead-sheet program so I know about using libriarys/basic knowledge but this seems really hard to me...

def projectName(): 
    print('PianoScript')
def projectGoal(): 
    print('MIDI to specifically-designed-piano-roll-for-reading-and-playing-piano converter')
The Questions:
  1. I need to open a midi-file and get all midi events in a python list. How do I do that?
  2. I am looking for the best python libriary for midifiles and I think that MIDIUtil is the best. Am I right(I hope someone with more experience in python and MIDI can help me)?
  3. How would you start with a project like this?

Hello,
due to new hobbies, the project you are working with sounds really interesting to me!
That said, the questions you posed are very broad. it's too much to take on all at once, in one thread (especially #3).

1. I need to open a midi-file and get all midi events in a python list. How do I do that?
Have you tried anything? Have you searched online for examples of how other people do it?
On your project building path, you will have a lot of searching and experimenting to do. This is just one example of it, so you better start tackling it on your own and get used to the process. We can of course help with specific coding questions, tips, correcting errors...

2. I am looking for the best python libriary for midifiles and I think that MIDIUtil is the best. Am I right(I hope someone with more experience in python and MIDI can help me)?
The subject you are dealing with is very specific. This is a general Python forum, so chances are you will find better suited audience for this question in a music-software community. Unfortunately I can't answer this question either.

3. How would you start with a project like this?
Now this question is very broad. There are articles written on the subject of software writing. Given that you asked a question like this, start with something smaller. Either a basic project, like a calculator (just an example, there are many options). Or you might prefer to start with implementing a little sub-part of your project idea. Such as reading midi files, storing the data in a list, displaying it in the console as the music is played, or so... This way you will build experience and get a feel of how coding process works. Then you can gradually move on with bigger ideas. Since your project idea (really cool one!) is not a straightforward coding exercise.
Sooner or later you will start using modules and packages. When you become familiar with them, you may start looking at your project design and translate the specifications/diagrams into modules, functions, classes... which your program will be made of.
Again, if you have specific questions, feel free to ask.
Good luck!

Thank you for the kind words!

Yes I made the diagram leadsheet with my first python program..
I learned already that i am asking too quickly, indeed first try to solve on your own. Currently, I am on the point where my (midi)program can open and display midi events on the staff!

(maybe you can recognize the piece from the screenshot;))

I will ask if I have specific questions!

Hello, how has the project been progressing? Have you gotten stuck at any point?

Could this be Moonlight Sonata by LWB? :)

Ah way too late sorry... But I am continuing this project and changed the direction. I created a music scripting language/lilypond-like application where you can enter music through text and the program renders the score.

This sounds impressive! I sure am interested to see the result. So feel free to share some screenshots or even snippets in the Code Sharing forum Wink

Currently it growed to the next level :) Now the moonlight sonata looks like this:
(since I cannot post images on this forum directly I will post the current code and the save file which you can open :)
