One thing I had meant to add (but forgot) was that you might find the 
DSSI Mono and Stereo Samplers useful for doing this kind of thing.  I'm 
sure you know all this, but I'll summarise their good and bad points.

All these plugins do is play a single sample per instance, triggered 
from a MIDI note, repitched if required, and optionally either heeding 
the NOTE OFF or playing to the end of the sample each time.  They're 
ideal for tracks where you want some simple repetitive pattern but you 
want to be able to tweak it and play it to note timing.

Because these plugins always load the sample into RAM and play it from 
there, they're not good for very long samples -- unlike Rosegarden's 
own audio file playback, which streams direct from disk for audio files 
over a certain size.

On the other hand this means they can be more efficient (and less 
buggy!) than playing straight from Rosegarden, if you happen to know 
that a sample can be played from memory when Rosegarden would normally 
play it from disk.

Also, ironically enough, because these plugins use libsndfile to load 
their sound files and libsamplerate to resample them, they actually 
support more file formats than Rosegarden and produce better-sounding 
output for files recorded at different sample rates from the current 
JACK one.  (They don't do high quality resampling for repitching, 
though, just linear resampling.  Laziness.)

They don't give you audio previews in Rosegarden, and of course you 
can't record direct into one.  You do still have the ability to add 
effects and things to them.
