Knifa has just released "Music Sequencer"

I've wrote a basic music sequencer in Lua. It has support for multiple tracks (or instruments, whatever you want to call it) too, changing BPM and the likes.

It's not exactly the most useful thing ever, but I got bored and made it for the fun of it :P

If you're going to make a song on it, it's very simple, you should be able to figure out what to do by reading the songs that come with it. Remeber that they are processed in HALF-BEATS and not a single one.

You can also add your own samples by doing something like this at the top of your song file.

Code:
V_TONE1 = AddSample( "file.wav" );

Then you would use that in your song scores/tracks
