@rhowaldt: absolutely, samples are the source material that benefit the most from this. Plugins seem almost boring in comparison 
And there’s absolutely no need for external hardware, the dedicated control surface is fully functional and has every feature exposed. It even features PC keyboard transpose and note entry (try pressing keys with/out the shift modifier!!)
That’s it’s based on the Duplex framework simply makes it easier to plug into various controllers, with bi-directional communication, control surface emulation etc. In other words, from a developer’s perspective, it takes care of a lot of the boring stuff that you don’t want to do over and over, each time you want to create something that makes music.
If you want to try it out, I just updated the download link (Duplex beta version thread)
