'''Human User Interface Protocol''' (commonly abbreviated to '''HUI''') is a proprietary [[MIDI]] [[communications protocol]] for interfacing between a hardware [[audio control surface]] and [[digital audio workstation]] (DAW) software. It was first created by [[Mackie (company)|Mackie]] and [[Digidesign]] in 1997 for use with [[Pro Tools]], and is now part of the [[Mackie Control Universal]] (MCU) protocol.

The '''HUI MIDI mapping protocol''' is a proprietary [[communications protocol]] for interfacing between a hardware [[audio control surface]] and [[digital audio workstation]] (DAW) software. The protocol allows a DAW and a connected hardware control surface to exchange [[MIDI]] signals that synchronize the states of their (virtual) sliders, buttons, wheels, and displays. The user can write [[console automation]] which can then be seen in the DAW.<ref>{{cite book |last1=Thompson |first1=Daniel M. |title=Understanding Audio: Getting the Most Out of Your Project or Professional Recording Studio |date=1 August 2018 |publisher=Berklee Press |___location=Boston, MA |isbn=978-1-4950-2875-5 |page=280 |edition=2nd |url=https://books.google.com/books?id=oHxuDwAAQBAJ&pg=PA280&lpg=PA280&dq=human+user+interface+hui+protocol&source=bl&ots=z6ePLwy7LK&sig=LKwEj0t-uCvNeLFWq29k1GSKQeI&hl=en&sa=X&ved=2ahUKEwjPr-O5idLfAhUEooMKHaBRCO84ChDoATAJegQIAhAB#v=onepage&q=human%20user%20interface%20hui%20protocol&f=false |accessdate=3 January 2019}}</ref>

== History ==

Created jointly by [[Mackie]] and [[Digidesign]] in 1997 for Mackie's Human User Interface (HUI), the first hardware control surface for Digidesign’s [[Pro Tools]]. By the time Mackie introduced the Baby HUI in August 2002, the protocol was supported by a growing family of DAWs, including [[Mark of the Unicorn|MOTU]] [[Digital Performer]] and [[Steinberg Nuendo]].

The HUI protocol was created jointly by [[Mackie (company)|Mackie]] and [[Digidesign]] in 1997 for Mackie's Human User Interface (HUI), the first non-Digidesign hardware [[Audio control surface|control surface]] for Digidesign’s [[Pro Tools]].<ref name=":1">{{Cite web|url=http://www.protoolsproduction.com/control-pro-tools-daw-controller/|title=Taking Control of Pro Tools with a DAW Controller|date=2017-02-16|website=Pro Tools Production|language=en-US|access-date=2019-05-16}}</ref><ref>{{Cite book|url=http://www.synthmanuals.com/manuals/mackie/hui/owners_manual/hui_om.pdf|title=HUI - Human User Interface for Digital Audio Workstations - Reference Guide|publisher=Mackie Designs Inc.|year=1998|___location=USA}}</ref> It was subsequently implemented by hardware controllers from manufacturers such as [[Solid State Logic]],<ref>{{Cite web|url=https://www.solidstatelogic.com/studio/aws/daw-control|title=DAW Control {{!}} Solid State Logic|website=Solid State Logic|access-date=2019-05-16}}</ref> [[Yamaha Pro Audio|Yamaha]],<ref name=":1" /> [[TASCAM]],<ref name=":0" /> and [[Novation Digital Music Systems|Novation]].<ref name=":1" />

=== Mackie Control Universal (MCU) ===

While HUI is still supported on the hardware side, non-Digi software has moved on to more open MCU and other MIDI control protocols as Digidesign (now Avid) has made extensive controllers with proprietary protocols that have much more rich capabilities but are part of a closed system.

In 2003, the Mackie Control Universal (MCU) protocol was introduced, combining together functionality from Mackie Control, [[Logic Control]] and HUI into a single protocol.<ref>{{Cite web|url=https://www.soundonsound.com/reviews/mackie-control-universal|title=Mackie Control|website=SoundOnSound|access-date=2019-05-16}}</ref> DAWs which support MCU (in addition to those which support HUI) include [[Ardour (software)|Ardour]],<ref>{{Cite web|url=https://manual.ardour.org/using-control-surfaces/devices-using-mackielogic-control-protocol/|title=Ardour Documentation: Devices Using Mackie/Logic Control Protocol|access-date=2020-07-28}}</ref> [[Ableton Live]], [[Studio One (software)|Studio One]], [[Steinberg Cubase|Cubase]], and [[Reason (software)|Reason]].
