Pattern problem

[Randomalan]

I've probably missed a trick in the help guide but here's the problem : In the sequence of patterns below I want pattern #1 to play as an intro - once only and the other 3 patterns to carry on playing in sequence ad infinitum. How do I stop #1 from coming in at the beginning every time. I'd be grateful for any help

<S100 R 1.1 2.4 3.2 2.2 4.1 3.1 2.1 4.1>
<100 B 60 20 60 20 60 20 60 20>
<100 B 60 1 60 3 60 5 60 6>
<100 B 60 4 60 6 60 8 60 9>
