Midi

Does anyone know how to write MIDI files in VB?

Any help would be appreciated.

are you talking about writing a file with the notes that you input into the computer?

If so, I have a question first: are you able to write binary files with VB?

No... I mean generating a MIDI file from scratch.

I found a few ways to do it with the API but it was long and tedious, and I was wondering if there was a shorter way.

if you can figure out a way to write binary files in VB, you can just write it with a few codes - just formating the file. midi files are binary, and they have a standard format (I know you knew it).

I don't know if VB can do what c does: in c, you can define a structure, and specify the bytes in every chunk (midi files are divided into chuncks).

I don't know if I'm clear or not.

.......wait a minute, take out your vb book and turn it to page 245, read the part called Processing Binary Files. I think you can also write your bytes into an array (ARRAY!!!!!!!!!!!!!OMFG I hate array) and save it into a binary file. I got homework to do tonight so I can't study it right now.

Yes, you can write binary files in VB, but the problem is figuring out the standard format of a midi file.

oh emily don't worry about that I just studied the file format on Sunday and I can help you with it at any time

I don't know how much you know about binary and hex. Do you know how to convert them into decimal?

You need to find a "binary file viewer", in order to open a midi file and analyze it. I'll be online tonight sometime.
