Hello, of cours this is the “Orchids signature sound” 
More seriously, this is indeed something that we witnessed a lot in our trials (and we gave it this nickname). And this is actually something that tipped us about a major flaw in the Partials computation. In fact, with medium complexity targets, the system tries to “over-optimize” with the remaining instruments and starts to try to put instruments where there is even a small-to-useless event (such as end of a sound where the loudness drops) … This lead to a strange staccato in the end.
We are actually working very hard to fix the partials-related issues and will make a new release (0.9.1) that fixes all of these problems before the end of this week !
All the best,
Philippe
