Yep, sounds like the three sons of Donald Duck, or the same names given to the drones on the classic Sci-Fi film Silent Running. The one I want to discuss is HUI and you'll notice the spelling 'cos this one is an old communication protocol between digital devices (Human User Interface). Developed well over a decade ago HUI was the initial protocol adopted by Digidesign (now owned by AVID) for communication between software and hardware, namely control surfaces. HUI uses MIDI as a language base and as such suffers from all the restrictions of this 8bit binary. Now just why NEVE have adopted it for use on their $100k console the Genesys I do not know - it is slow, clumsy and unreliable. I am fighting with the NEVE getting it to consistently speak to Protools and can only wish that the makers of the Genesys are well on their way to adopting a superior protocol, such as that developed by Euphonix known as EUCON - and guess what? Now owned by AVID! I wonder if this has anything to do with it? If I can find out I'll happily let you know.
