Michael:

It would be a surprise to me if Rosegarden couldn't handle triplets in 
importing from a MIDI file (I love three-against-two, and use it all the 
time).

I would think that from importing a MIDI file, it is only aware of the 
note-on/note-off events, and not any supposed notation behind those notes.

So I quickly recorded a simple three-against-two piano piece on my 
device, and saved it to a (type 1) MIDI file.

I imported it to Rosegarden (version 12.12.25, available with Lubuntu 
13.04), and it played what I recorded just fine.  I can't speak for 
later versions.

In looking at what was imported using the notation editor, it isn't 
expressing the notes as triplets against duplets.  A quick attempt at 
quantization didn't yield triplets either, but what I played was rather 
sloppy, and not precisely with the metronome (I usually play without a 
metronome).

So certainly it can import such notes from a MIDI file, but it may not 
(in the notation editor) show the triplets properly).
