Is it more like a trill where there is almost no perceptible pause between cuts
It's hard to know exactly what you mean because of the way your questions are worded.
In neither a trill, nor a cran, is there any 'pause'. Both techniques equally require "full closure" if they are to sound like what they are.
To show what I mean, a trill on F# in the 2nd octave (the most common one pipers do) is the alternating between G and F#
x xxx ooxx
x xxx xoxx
x xxx ooxx
x xxx xoxx
the G finger must fully close to create the F#'s; if it doesn't fully close you don't get F# but a wooly sound halfway between F# and G.
For crans it's lifting AND REPLACING a series of fingers to create a series of upper notes in between a series of clearly enunciated Bottom D's, such as:
x xxo xxxx
x xxx xxxx
x xxx xoxx
x xxx xxxx
x xxx oxxx
x xxx xxxx
Often the first gracenote is A because that can help get Hard Bottom D. That sequence of gracenotes there, AFG, is only one of many, because you can go AGF or FGA or GFA (which leaves the A finger free to separate D melody notes).
Then there's a different thing, a legato triplet FED, in context fingered off the leg, like this:
x xxx xxxx
x xxx xoox
x xxx xxox
x xxx xxxx
usually preceeded by an A cut. You can hear Paddy Keenan doing a load of these on his Doublin' album.
This is the 'cran' that fluteplayers often did in the old days, before Matt Molloy got everybody doing piping crans on the flute.
