Turns midi tracks into Clone Hero charts.

Alright, this thing is a buggy mess, but it works. Kind of. Feel free to fork this and do wathever, my Python sucks, but I hope it can be useful. Couple of disclaimers:

• The algorithm that places notes is very crude still, equal sections will play differently on different times, pitched notes like glissandos will count as one note only, and so on. It needs work, but it's playable and I've had a ton of fun with it.
• I did not make a stand alone program of this, but I did enclude a working python environment so anyone can run by starting "run.bat". If you want to setup your own env, though, just clone the repo and install the dependecies on the 'how to python' section.
• This only works on 64bit because I'm lazy. If you're on 32bit, change the bit in 'main.py' with 'x64' to 'x32' when KMC is called.
• The GUI is awful, but the program is worse, it may crash, restart and bug out of nowhere.
• Some midis don't work well, they get out of tempo. It's weird and will take some investigation to find out why.
• As of now, the program can only do 1 midi track. This is most times enough to make a fun Clone Hero chart, but some songs split their sections in multiple tracks, those won't, as you play a small section and the rest of the song will be just silent. I do want to make a "merge" option, so you can select multiple tracks and sections that you want to play. I kind of started this, but I'm way too lazy to finish it.
• To convert the song to "ogg", the format that Clone Hero plays, chm2c uses Keepy's KMC. Since this was just slapped together, it would take way too much time and work to put KMC embed in source, so the program is just called from within chm2c after the chart is generated. Read the pop up.

• Download the latest release and extract it anywhere you want.
• Run 'run.bat'.
• Choose a midi file.
• Choose the track you want to be converted into chart.
• Read the pop-up if you haven't.
• A folder with the same name as your midi file will be created with both chart and ini files for the song. That's the song folder.
• Render the midi file as ogg with KMC by clicking "File -> Render to OGG" and put it on the generated folder.
• Rename the ogg file rendered by KMC to 'song.ogg'.
• Copy and paste the song folder to your Clone Hero songs folder.
• Scan songs on Clone Hero and have fun.

Those will for sure occur, so here's a little list. If you run into an error that can't be solved by following the instructions, feel free to create an issue here on Github, put the midi file there and I'll take a look when I have some free time. Don't forget to also put in the error from the command prompt.

If this happened, something broke with the program, and not much can be done, try another midi. If you know python, check out the error on the command prompt.

Something is wrong with the 'song.ogg' file. Did you render the ogg file? Did you rename the rendered ogg to 'song.ogg'?

There are a couple of possible problems that may happen. Take a look at the list below.

The program is ready to deal with most standardly written songs. That means 4/4, constant tempo songs. The weirder the midi structure, the bigger the chance of the program getting lost. Tempo changes may work fine, while time signature changes won't work what so ever. The way notes are placed is very dependent on the time signature. If you want to implement this, feel free to do so, I'll take a look at your code and merge it. Another prime suspect for out of sync notes is the Midi Driver. Check if your Windows Midi Driver is working properly.

The algorithm for placing notes is far from perfect. If weird notes are the only problem, try changing the section size. The ways notes are spread depends on how they're read. If a group of notes has a wide range of pitches, a smaller section is better, for similar pitches, bigger sections are better. This means that if a song part is interpreted in different section, it may have different notes on Clone Hero. I'm open to ideas for improving the algorithm!

When the midi file is loaded, the number of notes appears on the side of each track. It's fairly common for midi writers to put empty tracks with their names and so one. Just choose a track that is not empty. If you chose a non empty track and the song is still empty, that's most likely a bug. Feel free to report it here.
