Also, if you go to the More Info page , I explain how to define and use your own rudiments to make bigger patterns. See this page for how to do this. 32 32nd notes that you either turn on or off. This is fine if you like to stick to one note type or sub-division in your patterns.
Most rudimental drummers prefer to mix note types in their patterns.
That's what I've done with this website. This has been designed to handle any mixture of note types as long as it all fits within the given time signature. You're able, if you're so inclined, to actually define, using a pseudo macro language, your own rudiments. Flams are supported as well as the ability to widen or shorten your flams. You can choose Intro and Transition Patterns, set the number of repeats, the start tempo and the amount to change the tempo per repeat.
