riff 4

I'm not so sure about the end of riff 4.
The ryhthm should be correct : -55- are 16ths
                               -5-5- are 8ths
                               -5--5- are 4ths	etc
                               -5________- means sustain 5 for _ 16ths
                                (half a bar in this case, 8 16ths)
