[LAU] how to manage expression control?

[confrey]

Hi everybody,
I wrote a few time ago about 'crescendo' in long notes, and I thank you 
for yours suggestes; now I'd like to know what's the finest mode to 
manage  CC #11 : I've began to use Rosegarden, and I've seen in matrix 
editor I can define a lines to manage expression, but it works by big 
steps only, I'd like a better and smoothly effect; which sequencer 
software can I use?
bye and thanks again
