mini notation: change multiple params at once?

[felixroos]

Just a quick idea: I was thinking about a syntax like

"c:1000 eb:500 [f:2000 g:300]".as('note:lpf')
// is equivalent to
note("c eb*2 [f g]").lpf("1000 500 [2000 300]")

So the same mini notation string can carry multiple param values, which are then assigned by as (or another name).

It could even allow to use more than 2:

"c:1000:a eb:500:e [f:2000:e g:300:i]".as('note:lpf:vowel')

This allows notating a rhythm only once, while having full control over each individual value.
Maybe values could also be optional:

"c:1000 eb:500:e [f::e :300:i]".as('note:lpf:vowel')
// is equivalent to
seq(
  note("c").lpf(1000), 
  note("eb").lpf(500).vowel("e"), 
  [
    note("f").vowel("e"), 
    lpf(300).vowel("i")
  ]
)
