First, you'll need BMS Editor and Viewer programs.
I recommend BMSE for editing and uBMplay for viewing. Click and scroll down to the download links on each page (Just prefix each link with an 'h', I'm trying to show the links. I hate bemanistyle's auto-link-replace feature)
ttp://ucn.tokonats.net/software/bmse/
ttp://ucn.tokonats.net/software/ubmplay/
Choose to install both programs to the same folder (Saves time).
Apologies if you already know about how to use BMSE, but just in case, here's a basic how-to.
If you're going to make a non-keysounded BMS (easier to make at first), just get an mp3 of your choice, find its tempo, and assign it to the WAV list (Double-Click on #WAV02 or higher)
Then click on the 'pencil' icon, and place a note anywhere in column 'B01' (Background sound). That location will start the BG music.
Click on #WAV01 in the list, and now you're ready to place notes everywhere. Click the green > (play) button to view how it is so far.
BMS creation gets much more in-depth, more than I could ever explain in a single post.
And if you make a BMS, I want to try it
