Should those numbers be _all_ different ?

Note that if you sum 1+2+3+4+5+6+7+8+9+10, that's already 55. How many
time units do you have per 48 seconds ? (do you have a base tempo at
all ?)

And then what do you want the distribution to be like ? Is there any
maximum duration of a chord, minimum duration of a chord, etc ?
