We are the music makers - producers?

There are a lot of factors. Both machines have a lot of different sounds depending on the position of the pots and condition of the pots. As well as the swing introduced by 'poor' midi timing there's the slight differences between hits which come from the analog nature of the machine. You can build all that into a sample player but I wouldn't try to draw any conclusions about the machines in total from the samples.

I've had 2 of each side by side in the studio and they had slightly different sound characteristics too.
