Elektron Tonverk

You can parameter lock (extensive) routing parameters, that says it all. I still think it lacks a little in functionality - it is a sample animal, but raw sample manipulation is rudimentary, sample housekeeping is also somewhat sparse, i.e. no search filtering, no removing samples from projects once they are allocated... stuff like that. But that aside it is a creativity powerhouse and it sounds fantastic, good headroom. Also a very seamless midi integration.
