New Post: How to read MIDI notes properly

Hello,

I'm trying to read the MIDI notes of one track with 6 channels properly, so I can export it to C++ code which can be read by another device (Arduino).

The first few notes sound right, but at some point it starts sounding weird. The start and end times are being calculated wrong, but I don't know why.

This is the full code, it's not much tho.

This is the MIDI file, which I edited to have 6 channels: http://dev-ch.com/files/818e6e15-8e92-1b1b-1a18-d0d8ffedcf23/piratesofthecarribean.mid

Any help is very welcome!
