SEEBURG HDLM 8 Firmware Updates

Changes

• fixed a bug when changing to DHCP Server from DHCP Client
• fixed a bug on project load when delay value was set to milliseconds or feet
• eq page: there is now a frequency scale in the background if not in GEQ mode
• Firefox is now again the recommended browser for all operating systems
• added additional resynchronisation handling on network failure
• all HDLM software is now ready for 64 bit systems
• lpi: added bandwidth parameter to PEQ and PEQ2 (e.g. peq 1khz 0.3oct -6db)
• lpi: added bandwidth and q parameter to HSHELF and LSHELF (e.g. hshelf 10khz q0.5 +3db)
• lpi: added MUTE command, which is equivalent to set the gain to the minimum possible value
• lpi: commas (',') are now also valid decimal points (2,3dB is equivalent to 2.3dB)
• lpi: utf-8 minus symbol is recognized correctly
• lpi: fixed a bug in loudspeaker's curve plot at low frequencies (audio output was not affected, just the drawn curve)

Changes

• added PEQ2 in lpi languange. PEQ2 is compatible to parametric eqs used in the Harman Group and many other pro audio companies
• webinterface: right-click on the eq-graphs does not show the ugly "About Flash..."-menu any more
• webinterface: adjusted contrast of the eq-graphs for better readability
• fixed a bug in project export where the interface could freeze in some circumstances
• fixed a bug in network configuration where subnet bits may be wrong if HDLM was updated from version earlier than 3 (which resulted in not recognizing the GoHDLM App)
• GoHDLM App: changed reconnection behaviour. The app will try to reconnect to the last screen when coming from sleep, from background or by a lost connection

Changes

• network broadcast address is now calculated correctly for large networks with addresses beyond x.x.x.255 (will affect only network link groups and remote control using GoHDLM)
• version information is now shown for a short time in the boot phase

Changes

• raised drive strength of some internal signals to prevent random noise and crackling in harsh environments (MkII-hardware with 4 inputs only, no effect on hardware with 2 inputs)

Changes (summary)

• new peak limiter
• delay unit can be set to milliseconds
• web interface app is now full-featured
• many bugfixes

Changes (detailed list)

New Device Features

• new peak limiter with arbitrary release time (sounds much better)
• new attack/release/peak release parameters in input bus compressors
• added milliseconds as selectable delay unit
• updated lpi (loudspeaker programming interface) to version 2.2 (new: limiter time parameters)

Major Update of the Web Interface App

• improved re-connection handling, especially on network failure
• right click or double click on an input field (gain, frequency, q, delay) shows a fader
• loudspeakers and folders can now be moved by dragging (if not locked)
• the lock of loudspeakers and folders will be removed by re-entering the lock code
• added output metering with single-channel mute buttons
• added delay unit selector in output properties
• added copy channel function by drag & drop
• added Project Management: New, Load, Save, Delete, Import, Export Projects
• added Project Description
• added Project Security settings and proper lock code handling
• added global system settings page
• added digital input state
• added notification line in the top center showing system alerts
• added physical input mapping overview in input map list
• added legend to frequency plot thumbnails
• added lpi reference documentation to the loudspeaker manager
• added "Duplicate Loudspeaker". Duplicated Loudspeakers are un-locked by default.
• added connection status indicator
• reversed polarity and delay > 0 will be displayed coloured
• lpi editor has now syntax highlighting and error reporting
• level meters have now a scale legend
• double click in the loudspeaker library opens the editor
• lpi configuration now readable even in locked-state
• all eq parameters are now visible at the same time
• changed input dynamics threshold unit from dBFS to dBu
• lpi folder names and positions can be locked/unlocked
• frequency plot thumbnails now implemented natively in html5
• level meters now implemented natively in html5, using less cpu power
• online demo available

Bugfixes

• fixed a severe bug that did not update all eqs properly when a project was loaded in some circumstances
• fixed a bug in exporting project with names containing foreign characters
• fixed a bug with project security settings after loading or saving a project
• selection of channel status better to read in the display of MKII-hw
• maximaum delay distance depends now corrcectly from ambient temperature which can be set in the system settings
• improved precision in delay distance calculation
• fixed coefficient calculation for LR12 and LR36 HPF/LPF filters
• web app: now works with Firefox 29.0
• web app: fixed lpi editor height
• web app: Output EQ page: fixed an issue with initial selection of the output channel
• web app: fixed a bug in renaming a folder of loudspeaker database
• web app: fixed a bug in updating the lpi frequency plot in case of multiple users edit different loudspeakers
• web app: loudspeaker folders will not close anymore if being re-clicked
• web app: fixed a bug with initial drawing of input and output eqs

Firmware Update for all HDLM 8 devices (do not rename!): HDLM8_Firmware_3_1_0.bin (16 MByte)
This is the stable production release version for both MkI (2 analog + 1 digital inputs) and MkII (4 analog + 2 digital inputs) hardware.
Projects, Loudspeakers and System Settings will not be touched by the Firmware Update.
ATTENTION: It is strongly recommended to power-off and power-on again the HDLM before doing a firmware update.
