# SC3
SC3 reorders the inputs, hsc3 does not.

# hsc3
The function klankSpec can help create the 'spec' entry.

> import Sound.SC3

> let s = klankSpec [800,1071,1153,1723] [1,1,1,1] [1,1,1,1]
> in audition (out 0 (klank (impulse AR 2 0 * 0.1) 1 0 1 s))

A variant spec function takes non-UGen inputs
> let {f = [800::Double,1071,1153,1723]
>     ;u = [1,1,1,1]
>     ;s = klankSpec' f u u}
> in audition (out 0 (klank (impulse AR 2 0 * 0.1) 1 0 1 s))

There is a limited form of multiple channel expansion possible at
'specification' input, below three equal dimensional specifications
are transposed and force expansion in a sensible manner.
