• Added Support for Hilo Remote Control.  Added the ability to fully remote all of the volume controls and level meters of the Hilo from the host computer.  The Hilo Remote Control application is initially available on Windows and OS X, with an iPad version available on the Apple Store as soon as it is approved by Apple. 
• Added Support for LT-TB Thunderbolt Interface.  Changed channel names from USB Play and USB Record to Thunderbolt Play (TBT Play) and Thunderbolt Record (TBT Record).
• Added Support for LT-FW FireWire Interface.  Changed channel names from USB Play and USB Record to FireWire Play (FW Play) and FireWire Record (FW Record).
• Added Support for LT-HD ProTools HD Interface.  Changed channel names from USB Play and USB Record to PTHD Play and PTHD Record.  Please note that Hilo firmware update is not possible using a LT-HD card since it has no MIDI interface. LT-TB, LT-USB or LT-FW may be temporarily installed to update the Hilo firmware, if required.
• Added Support for no LSlot Interface.  Removed all references to LSlot channels if no LSlot device is detected.  Please note that it would not be possible to update the Hilo firmware without an LSlot device. 
• Removed LT-USB Mode from Tools Menu if LT-USB is not installed.
• New Standard Menu.  Added new 'Standard Menu' on the Display Page which provides a much simpler interface for the most used functions.  Backlight control; Line In & Line Out Trim; About Hilo and the new Source Select option described below.  To return to the previous menus, simply press the 'Advanced Menus' button.  Please note that the ADAT I/O is disabled, Digital In Sample Rate Converter is set to ON and LT-USB Mode is set to 8-channel when using the Standard Menu.
• New Source Select option in Standard Menu.  This new option allows for simple routing of the audio coming from the host computer (USB Play; Thunderbolt Play...) to all physical outputs.  In addition, a single source may also be mixed with the host computer audio from the Line In or any one of the digital inputs.  This duplicates the basic features of the Output Mix Routing Page and Digital In Source Selection. 
• New Knob Settings.  Located on the Display Page, the new Knob Settings function allows the user to adjust the volume of any of the stereo outputs from the rotary encoder.  A maximum of 3 outputs may be selected at one time.  Pressing the rotary encoder will toggle between the selected outputs.  Previously only the analog Monitor Out and the analog Phones volumes were able to be controlled from the rotary encoder.  Now the following digital volume controls may also be selected: Line Out; AES Out; SPDIF Coax Out; SPDIF Opt.
• New Show/Hide Settings.  Moved the three separate button functions to a new single button with a popup dialog box to make room for the Knob Settings and Standard Menu buttons.
• Output Mix Routing Page: Source Channel Select function 'Sum' changed from -3.0dB to -6.0dB attenuation.
• Dither enabled when digital volumes are active.  Triangular PDF dither is enabled on each output independently when source or master digital volumes are set to levels other than unity gain and off/mute. This prevents noise modulation distortion caused by digital attenuation, but still provides a bit-perfect digital signal chain when volumes are set to 0 dB.
• Mute ADAT In or USB Play sources if the inputs for those devices are not locked.  This prevents any signal from those channels appearing as audio anywhere within Hilo.
• Please note that when using the Hilo with the LT-TB running at 176.4kHz or 192kHz, Play 9-16 and the ADAT inputs are not available to be routed as sources to any of the 32 outputs.  Please use Play 1-8 for the 4X sample rates.

Version 6.1    April 9, 2014

• Fixed issue with digital i/o that might cause the digital i/o to not function properly.
• Fixed issue with battery voltage display when battery is connected.  Now the Info menu shows if the Hilo is being powered from the "Mains AC" or "Battery" and the voltage of the battery.
• Updated About Hilo to show 6.1 firmware and application version.
