Live I would say it makes perfect sense to compress an accordion, just as you would do with vocals as it is the same idea
But I know very little about this as this is always done by the sound engineer.
Compression... sometimes good, unfortunately more times bad than good, but it all depends, of course.
First what is compression? Basic compression takes the wave peaks made by the higher volume sounds and lowers them. This is sometimes why the accordion comes out a bit louder, because it doesn't make the accordion louder, but it makes the other parts of the image (like the singers and drums that are also being compressed) quieter.
More advanced compression reduces the peaks and increases the volume of the quieter passages.
My big dislike about compression is that when recording the accordion, it takes out a LOT of the dynamics from of the recording. All that hard work we place to make the quiet parts quieter and the louder parts louder are "evened out" making it all relatively the same volume. There goes all your hard work in adding feeling to that piece in the first place!
Though this can help in a live situation, AND it helps in reducing distortion, on a recording, too much compression is the kiss of death on a song with a lot of loud and soft parts. For reducing accidental distortion due to too high a peak (too loud or too much gain on a channel), a limiter is a better idea. It keeps you from distorting, but does not affect the quiet parts of your songs, retaining your dynamic range.
When do I use compression? It's very much both song specific and even very channel specific. In music it is VERY subtle if used at all. Mostly, I use compression for vocals. When making my videos, my voice is compressed. I *want* that to be a very even and consistent volume level across the video.
