1. inplace assignment

for ((i=0; i<13; i++)) do echo $pat pat=${pat:2:0}${pat:0:2}

1. shift the pattern
2. ${name:offset:length}

done

cat << end

} } end

1. bash clap.sh | midge -o clap.mid; timidity clap.mid (straight from bash to timidity without going through all the steps)

OR

pat="xxx_xx_x_xx_"
