Sound Devices MixPre Series firmware - (v 3.01) is an update for the MixPre-3, MixPre-6, and MixPre-10T as well as the M-models: MixPre-3M, MixPre-6M, and MixPre-10M. This update provides new features and performance enhancements to previously released firmware.

Last update December 14, 2018

Changes introduced in 3.01 include:

Fixed

For all models:

  • The potential loss of recorded audio due to a failed automatic file split has been eliminated.

For MixPre-3, -6, and -10T only:

  • Media slow messages no longer appear when invalid or intermittent Aux In timecode is used with pre-roll.

3.00 - December 10, 2018

New

For all models:

  • USB control from the Korg NanoKontrol Studio, Korg NanoKontrol2, Akai MidiMix, and Novation Launch Control XL USB control surfaces. Other USB control surfaces are not supported. Includes support for fader, trim, pan, low cut, reverb, solo, mute, track arm, monitor, transport control, LR output level, and user-programmable shortcut buttons.
    Note: available features depend on the control surface being used and whether Audio or Music projects are enabled. For more information, see the USB Controller chapter in your MixPre User Guide.

For MixPre-3, -6, and -10T only:

  • Pre-roll: saves up to 10 seconds of audio before the “record” button is pressed. Select up to 10 seconds of pre-roll on the MixPre-10T and 5 seconds of pre-roll on the MixPre-3 & -6. Pre-roll time is reduced at 96 kHz and higher sampling rates.

For MixPre-3 and 3M only:

  • Phase invert option now available for the MixPre-3. Phase invert is already available for all other MixPre models.

For MixPre-6 and -10T only:

  • Ambisonics and binaural recording/monitoring (-6 and -10T Audio projects only). Requires installation of the free Ambisonics Plugin available at the Sound Devices Plugin Store. See [Ambisonics user guide link]

For all M models and Music projects on models with Musician Plugin:

  • Bluetooth LE wireless remote control using the Android or iOS Wingman app. Includes 12-track monitoring, mix metering, transport control, time counter, track naming and arming.
  • Support for the new Windows ASIO driver, v2.9.92.1. This enables a MixPre running a Music project to be used as a multichannel USB audio interface with Windows computers. This ASIO driver is required when using the MixPre-3M, -6M, or -10M or when running Music projects in the MixPre-3, -6, or -10T.

Known Issues

For MixPre-3, MixPre-6, and MixPre-10T:

  • The 4 GB automatic file split feature is not working correctly, resulting in lost audio. If your workflow requires recording for long duration, manually split the file by pressing the record button or backdate your firmware to 2.21.

Changed

This lightweight, 10-input/12-track recorder offers world-class sound quality, flexible powering, and built-in, highly accurate timecode generator/reader – perfect for production sound mixers, field recordists and sound designers. See https://www.sounddevices.com/products/recorders/mixpre-10t

1.20 - Sept. 28, 2017

New

  • The MixPre-6 now offers 4-channel linking. (This feature is only available on the MixPre-6.)
    When channels 1-4 are linked, gain, fader, limiters, track arming, low cut filters, and input delay are all linked and controlled from Channel 1 screen and knob.
    Note: Available options vary based on set mode.
  • Input Delay, a feature already available on the MixPre-6, is now supported on the MixPre-3. Available on channels 1-3, adjustable from 0 to 30 ms in 1 ms increments.

Changes

  • In this firmware, the Linking feature was moved from Custom Setup > Gain > Advanced to Custom Setup > Channel > Advanced. This change now lets you link inputs while still having the option of one or two gain stages.

    Users wanting to link inputs, but control all levels from the front-panel channel 1 knob should set System > Mode to Custom and then in Custom Setup, set Gain to Basic and Channel to Advanced.

    Users wanting to link inputs with two gain stages while in Custom mode, ensure that Gain and Channel are both set to Advanced. Then, you can adjust gain levels for linked channels from the Channel 1 screen and adjust fader levels for linked channels with the Channel 1 knob.

Fixed

  • Corrected offset in timecode file stamps when using external LTC via the 3.5 mm Aux Input.
  • Limiter Indicator would not properly show activity after unlinking input channels.
  • Input delay for linked channels 1-2 incorrectly applied to linked channels 3-4 after power cycle.

  • Channel 5 and 6 did not correctly show limiter activity when Input Source was set to Aux In.
  • Clip indicator showed twice for one clipping event.
  • Changing headphone gain while in the Solo/Mute screen caused incorrect monitoring and routing of signals to the headphone output.

1.00 - Initial Release

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

Sound Devices recommends saving a setup file prior to loading new firmware.

Prepare to Update

  1. Download the MixPre firmware file MixPre_ 3.01.zip using the link below.
    From the zip archive, extract the file within named MixPre_ 3.01.prg file. Copy this .prg file to the root level (not within a folder) of an SD memory card that has already been formatted by the MixPre recorder.
  2. Power the MixPre via USB-C to external DC power or via "fully charged" batteries. Do not perform the update with low batteries or unstable power sources.
  3. Insert the SD card with the .prg file.
  4. Power on the MixPre.
  5. Navigate to System > Update Firmware and follow the on-screen instructions.
  6. When the update is complete the recorder will power cycle itself. The version number MixPre_ 3.01 will be displayed briefly on the splash screen while booting up. A message box appears "Firmware updated successfully Version:MixPre_ 3.01". Tap "OK". Please note any changes or additions to the main Menu (if applicable). Consult product documentation for details.
