The Bo Diddley Beat is worldfamous; everybody knows it (though not necessarily under this name) - here's a drummer showing it in detail: https://www.youtube.com/watch?v=YH2N2zgf4MQ

I'm very surprised that it's NOT implemented in B.i.a.b. with all its emphasis on American stuff and patterns... I was so sure it was until I found this thread here - and am somewhat disappointed now since I need not just the beat but the whole pattern for a new song of mine right now and was sure I could manage to put up the playback with my B.i.a.b. .... frown
