Hi Hugh,
The trick is to start off with a drum beat , which you loop ( just repeats itself )
next add a bass line and work forward from there, Not as easy as choosing a style
but a lot more flexible and unfortunately time cosuming
But I hope to put together at least one track done completely on the Ipad this summer
when I am at the caravan , just my ipad and a midi keyboard, certainly a challenge
