Firmware Update procedure


Version 3.0
June 2017

This is a major update with a lot of enhancements and bug fixes. See firmware v3.0 info sheet for more details.

KNOWN BUGS

  • Option card 4 channels out is not working properly: configuration is not restored correctly after a power cycle and audio is corrupted with click noises. A fix will be released soon, use version 2.5 if you need the 4 channel outputs of the option card.

CHANGELOG

  • Fixed SD card ERROR and SPEED ERROR
  • Enhanced note snippet list. Selecting an item will add it to the note (vs replace it). Selecting it again will remove is from the note.
  • Metadata tape can now be freely edited (12 chars max). When set, all audio files are stored in the path /PROJECT/WORKING DAY/TAPE. When empty, files are stored in /PROJECT/WORKING DAY and tape value is the working day
  • Added metadata take type menu, allowing to select the following: FALSE START, NO GOOD, CIRCLED, WILD TRACK, PICKUP, REHEARSAL, ANNOUNCEMENT, SOUND GUIDE. Take type is stored in the iXML metadata according to specification release 2.01
  • Added configuration save/restore to /from SD card (see menu SETUP/SYSTEM/BACKUP/RESTORE). Sub-menu SAVE OPTIONS allow user to select what should be saved in the configuration file
  • Added main screen peak-meters pages (horizontal, vertical)
  • Added limiter to headphones output (HEADPHONES/SETUP)
  • Added limiter to mix tracks (MIX/SETUP)
  • Increased headphones and output preset count from 4 to 8
  • Added headphones presets selection from main screen when level is locked (use rotary encoder)
  • Added RF64 (https://en.wikipedia.org/wiki/RF64) encoding. This format is automatically used if max file size is > 4GB (set it in menu SETUP/RECORD SETTINGS/MAX FILE SIZE). Max file size is now 45GB, but default value remains to 4GB for compatibility reason
  • Added input delays (up to 96k, disabled at 176.4 and 192k)
  • Added project name selection list. Up to 8 project name can be defined in (METADATA/PROJECT)
  • Increased track name and note snippet list length from 8 to 32
  • Added “SHOW F. START” button in TAKE LIST menu, allowing to view false start takes
  • Decreased default alarm level
  • Modified default behavior for input gain long press knobs: now toggle phase reversal (instead of track arm)
  • Added link in sound report title, allowing to download data as CSV file
  • Full rework of the web interface, which allow now to modify monitoring, outputs, user settings, as well as metadata, last takes or track arming
  • Various minor bug fixes and interface modification, such as meters hold returns smoothly, added reset button in filetag menu, fixed battery time to empty, …

Version 2.5
November 2016

KNOWN BUGS

  • A faulty SD card ERROR or SPEED ERROR can occurs during record. It happens mainly with low track count (1-3) and high sampling frequencies, more frequently to the SD2 card slot.

CHANGELOG

  • Added SX-AD8+ and SX-RC8+ operation from SX-R4+
  • Fixed timecode accuracy (was not accurate when cycling power with 23.976 and 30 fps). Also fixed some drift when switching from EXT JAM SYNC to the same frame rate.
  • Fixed SD card filename bug (same filename in a folder).
  • Fixed phase reversal input level issue: when using fader mude, a phase change using a push button assigned function can corrupt the input level
  • Fixed take number generation: wasn’t correct when scene changed during recording
  • Minor interface bugs fix

Version 2.4
July 2016

KNOWN BUGS

  • Modifying metadata of an existing take with the HTML web interface results in a bad filename of next take to be recorded
  • 23.976 & 30 fps timecode formats are not accurate after a power cycle

Version 2.4 is a fix for version 2.3, which has a major bug.

INFO
It is important to apply a full factory reset as described in the simplified update procedure to prevent running new firmware with an old configuration.

CHANGELOG

  • Fixed timecode bug (was not correct on SD2)
  • Fixed SD card ‘SPEED’ error
  • Fixed monitoring bug
  • Fixed take edition bug (metadata wasn’t saved properly)
  • Fixed alarm level (was active even when disabled)
  • Fixed take number generation (wasn’t correct if a take was shot with identical scene name)
  • Fixed sound report (false start takes were displayed and projects were not filtered)
  • Fixed system instability involving 4 channels output option card and sampling frequency changes
  • Fixed monitoring bug for 4 channels output option card (mix channels weren’t mapped)
  • Enhanced WiFi communication
  • Added WLAN channel selection for Access Point (AP) mode
  • Minor interface bug fix & enhancement

Version 2.2
May 2016

CHANGELOG

  • Added optional XLR5-M output card support
  • Fixed input level bug: when entering fader mode with pot closed, level was frozen to MUTE.
  • Fixed track menu bug: in some rare case, modifications were not saved
  • Fixed SD card ‘SPEED’ error

Version 2.1
March 2016

NOTE
Official version jumps from 1.4 to 2.1; version 2.0 only exists as beta. If you’re running version 2.0, please update to version 2.1.

KNOWN BUGS

  • XLR inputs levels remain fixed to MUTE. In fader mode, the input level can be modified using the rotary encoder in the input menu. However, if the input level is MUTE, input level change does not work. Workaround: do not mute inputs before entering fader mode.
  • Record sometimes fails on a SD card with the ‘SPEED’ error on the card. More frequent with low track count (1-2) on high speed cards.

CHANGELOG

  • Fixed playback channels swap
  • Fixed playback timecode (wasn’t displayed)
  • Fixed timecode accuracy
  • Fixed 176.4/192k operation
  • Fixed record start: under some rare condition, record start could be ignored
  • Fixed power failure filetag: was identical to previous take
  • Fixed ambient light sensor calibration and auto dim mode
  • Added User Settings menu
  • Added timecode date in user bits
  • Added system time zone
  • Added fader operation mode
  • Added SD2 Mix Only recording
  • Added 24bits WAV file recording/playback
  • Added note field in Tag Last Take menu
  • Added track coloring
  • Added meter range user selection
  • Added sound report file generation
  • Improved monitor/mix menu: presets are now independent from each others
  • Improved audio performance and behavior
  • Improved various menus (Inputs, Monitoring/Mixing, filetag, push buttons, date/time, split Record Tracks menu into Rec Tracks and Mix menus)
  • Improved HTML5 web remote application
  • Minor bug fixes and interface adjustments

Version 1.4
November 2015

Version 1.4 is a fix for version 1.3, which has a major bug.

KNOWN BUG / INFO

  • Sampling frequencies of 176.4k and 192k not yet supported
    WAV file creation time may be incorrect due to timezone
  • USER SETTINGS menu is not implemented
  • Modifying playback position can result in channel swap

CHANGELOG

  • Fixed file system (setting file to hidden was incorrectly implemented)

VERSION 1.3
November 2015

KNOWN BUG
Applying a false start will corrupt the file system, making some files unreadable. Please update to version 1.4.

NOTE
Once updated, press AND HOLD REC button until boot screen appears to power up the SX-R4+.

CHANGELOG

  • Fixed monitor presets: wasn’t restored at boot time
  • Fixed take list menu: selected take timecode wasn’t correct
  • Fixed pop noise during playback start
  • Fixed AUX AES output: channel status is now in pro mode

  • Added a config save button (SETUP/SYSTEM) to force configuration save (done at power down)
  • Player: loading a take no longer begins automatically playback; encoder can be used to modify playback position (1 step = 1%), to change headphones level, enter pause or stop states.
  • Various minor interface improvements
