Rules
No copying from library or subreddit
Be original. Don't just take some random expression, change a value or two (or nothing at all) and pretend it's yours.
Don't overuse fractals
Your song shouldn't mostly consist of fractals (like t&t>>8
or t|t>>4
). This doesn't mean you're not allowed to use them, however.
Keep your expressions short
The limit is 12k characters. You'll probably not run into this limit, unless you're attempting to use PCM data or something similar.
Don't take too long
Each season has it's own end date. Make sure you submit your expression in time.
