So I have found this website that generates note patterns and I've found a few that I like... And I want to transpose them to paper from off the genrator however I'm not able to tell what type of notes are being played (quarter/eighth/ sixteenth - you know the strum pattern as labeled on the bottom of the image)

Link to the website is: http://www.drumbot.com/projects/key_chords/
The thing we're missing here is the time signature. Without a time signature, I know nothing more than to play two strums per beat. Is it 4/4, 3/4, 2/2??? I can't tell.
