Last update November 9, 2011

Changes introduced in 2.67 include:

Fixes

  • Low level File system improvements.
  • DC offset removed when HPF is enabled for high sample rate recordings.

Known Issues

The list below are the published known issues for the latest 722 Firmware.

  • If a single storage medium (i.e. CompactFlash card) is selected/available for recording and it is unintentionally removed the unit will briefly show that the volume has been taken off-line, but the display will still indicate recording and the record LED will remain illuminated for up to 30 seconds or until STOP is pressed.
  • When initiating a repair on an unformatted volume (not likely...but), the unit will begin the process and lock up, requiring a hard shut down.
  • FireWire storage volumes with a PL3507 FireWire chipset and hard drive fail the speed test. Threre is a problem reading from these external drives. There are no problems writing to drives of this type.
  • These known issues will be addressed in future revisions of firmware.
  • Cue Markers are deleted if file is automatically split.

2.67 - Present Release November 9, 2011

  • fix - Low level File system improvements.
  • fix - DC offset removed when HPF is enabled for high sample rate recordings.
  • posted November 9, 2011

2.66 - Released July 28, 2010

  • fixed - bug in which the recorder's drive(s) would would not properly mount when connected via FireWire to Mac OS X 10.6 (Snow Leopard).

2.65 - Released November 16, 2009

  • new - firmware revision number shows in boot up splash screen.
  • new - ability to mark a take as 'NG' (No Good). Typically used to identify a take as not the one to be used in post, although there may be sections of it which may be useful. Data stored in the iXML chunk.
  • new - STOP+LAMP shortcut for quick access to Circling or NG'ing the last recorded take.
  • new - add ability to change take status of any take from the take list.
  • new - addition of iXML (v1.52) parameters including <FALSE_START>, <NO_GOOD>
  • fixed - RF hash/noise no longer causes the recorder to incorrectly stop recording in ExtTC/cont - Auto Record mode.
    It will only stop when stationary TC code is detected.
  • change - When daily folders are selected, the daily folder is only created when record is first pressed. This prevents empty daily folders being generated if the 7-series is powered up every day but without recording anything. This also applies to the generation of top level and bottom level folders.
  • change - Drive "Erase" menus renamed to "Erase / Format".

2.63 - Released April 16, 2009

  • change: enhanced write algorithm to significantly improve real-time multi-track recording to DVD-RAM even while simultaneously recording to 2 media
  • new: LCD scrolling direction menu enables user to select which direction the rotary encoder scrolls through the menu
  • fixed: drive warning corrupt file bug

2.61 - Released March 16, 2009

  • fix - condition where keyboard combinations pressed with a connected keyboard (via the CL-1) could freeze the recorder.
  • fix - condition where Windows Media Players-generated WAV files would not be recognized or playable on the recorder.
  • added - periodic, automatic file header saving during recording to preserve WAV file integrity in the event power is lost during recording. Does not apply to FLAC or MP3 recording.
  • added - menu option to allow display of gain settings instead of sample rate/gain in the LCD.
  • added - latching tone - press and hold tone button >2 secs to latch on.
  • added - option to enable tone activation during record. Set in the Tone: Record Lock menu.
  • added - menu to prevent start up messages appearing at power up.
  • added - default 'tape' metadata if mid-level (daily) folder is set to none (important for EDL based workflows).
  • change - 10 Hz steps in the tone generator frequency.
  • change - scrolling through menu made more intuitive.
  • change - remove drive repair function and associated menus.

2.54

  • fixed - SPEED and TAKE tags were sometimes not written the BEXT chunk when the recorder was in EXT_TC AUTO or EXT_TC/CONT AUTO. This bug did not affect the iXML tags - they are always correct
  • fixed - The REC: Timer Start/Stop function did not function if the recorder was set to record to daily folders and the record start time was after midnight.
  • new - added beeps to Rec-Pause Mode, so beeps occur when recording is paused and un-paused.

2.48 - Released June 04, 2008

  • fix - MP3 time code stamp bug - time code was not getting stamped correctly in the ID3 tag

  • added - Family UID added to iXML metadata
  • change/fix - "record pending” notification when a record command has been given and the DSP is not available to begin recording.

This improves the overall performance and reliability of the CL-1 in particular. “Record Pending” also replaces the “Busy” notification.
  • change - CompactFlash formatting now adds a partition so that CF cards can be exchanged between all 7-Series Recorders including the 788T.
  • change - poly files no longer contain unused tracks. The 7-Series will no longer record zeros to unused tracks.

  • fix - metadata note data saving. When notes were added and then edited, the edits occasionally did not take affect. Bug introduced in 2.34.
  • fix - when recording FLAC to CF, the recorder had the possibility of producing a file of length 0 seconds.
  • fix - when changing from FLAC format to MP2, the unit had the possibility of locking up.
  • fix - lockout of transport controls now operating properly.
  • fix - gain display only shows when gain knobs are turned.
  • change - estimate of available drive space when recording FLAC format. Original estimates too optimistic.

2.34 - Released September 25, 2007

All other operations work the same. Note that low-cut and phantom are not permanently linked. i.e. once channels are linked, low-cut and phantom can be individually set for each channel.
  • addition - folder options menu with folders/subfolders for project, daily, scene, and name-your-own folder
  • addition - now prompted to generate new daily folder (for users who are on a set over midnight). Before creating a new daily folder, the unit checks to see if one exists for the previous day. If so, it prompts the user to see if they want to create a new one.

Please read and follow the steps below carefully. You may want to print them before upgrading firmware.

Sound Devices recommends backing up any existing audio data that may reside on the recorder. While no data on the storage is changed during the update process, it is best practice to backup the unit. In addition, it is highly recommended to save the current device settings since a firmware update can result in settings changing to factory default.

Prepare to Update

  1. Download the 722 firmware file 722_2.67.zip using the link below.
    From the zip archive, extract the file within named 722_2.67.prg file. Copy this .prg file to the root level of a SD or CF memory card. Do not place the file in any folder. Do not place the 722_2.67.zip file on the SD or CF card. The card must be formatted as a FAT32 volume.
  2. Apply Update to 722
  3. Power the 722 from external DC. Do not perform the update with low batteries or unstable power sources.
  4. Power down the 722 if it is already powered up.
  5. Insert the SD or CF card with the .prg file.
  6. Power on the 722.
  7. Navigate to Setup Menu option SYSTEM > Update Firmware and follow the on-screen instructions.
  8. When the update is complete, power down the 722.
  9. Power the 722 on. The version number 2.67 will be displayed briefly on the splash screen while booting up. Please note any changes or additions to the Setup Menu (if applicable). Consult the 722 User Guide and Technical Information for details.
