I look forward to seeing this. There isn't enough Scandinavian music
available on the web.

We've said this all before. Rolls are instrument (and player) specific.
The whole idea of the roll, unlike classical ornament notation, is that it
be generic (unspecified) and left for the player to determine.
This is a "good thing."
I know the question was phrased in terms of the +roll+ notation, but it is
equivalent (near as I can tell) to the following macro notation. [Thanks to
Phil Taylor and his descriptions of roll macros in BarFly, of from which
this is drawn.]
Breandan Breathnach, in the CRE, specifies this for fiddle
rolls. Other instruments were specified with rolls
appropriate to their inherent limitations.
m: ~n2 = (3o/n/m/ n
m: ~n3 = n (3o/n/m/ n
Banjo style rolls. (Sometimes used on fiddle too.)
m: ~n2 = (3nnn
m: ~n3 = (3nnn n
Flute rolls. They can be generalized to this:
m: ~n2 = (3p/n/m/ n
m: ~n3 = n (3p/n/m/ n
but the bottom and top notes have to be handled differently.
m: ~C3 = C (3E/C/D/ C %Cranns on C?
m: ~C2 = (3E/C/D/ C
m: ~c3 = c (3e/c/d/ c
m: ~c2 = (3e/c/d/ c
m: ~D3 = D (3F/D/E/ D %and on D?
m: ~D2 = (3F/D/E/ D
m: ~d3 = d (3f/d/e/ d
m: ~c2 = (3f/d/e/ d
Henrik Norbeck reckons that rolls should be timed like this,
based on experiments with a MIDI sequencer.
m: ~n2 = {o}n{m}n
m: ~n3 = n{o}n{m}n
He specifies that the gracenotes should take their time from
the following note, so perhaps they should be written as
~n2 = o/4n3/4m/4n3/4
~n3 = no/4n3/4m/4n3/4
