Digitakt II OS Release Notes

Last updated Mar 20, 2025


How to upgrade

Upgrading from within the OS
  • Connect the Elektron device to the computer via USB and switch it on.
  • Open the Transfer application on your computer.
  • On the Transfer CONNECTION page, set the MIDI IN and MIDI OUT ports to your Elektron device.
  • On the Transfer DROP page, drag and drop the OS file. The OS file is then automatically transferred to the Elektron device and the OS update initiates. A progress bar is visible on device screen when receiving the OS.
  • On your device. Press [YES] to confirm the OS update.

If your current device OS does not fully support Transfer, you will be automatically directed to Transfer’s LEGACY OS UPGRADE page after you drag and drop the OS file on the Transfer DROP page. Follow the instructions on the LEGACY OS UPGRADE page to proceed with the OS upgrade.

When the update is done the unit will restart by itself.

Upgrading from the Startup Menu
  • Connect the Elektron device to the computer via the device’s MIDI port. (You cannot use the USB port).
  • Hold down the [FUNC] button while powering on the Elektron device. This takes you to the STARTUP menu.
  • Press the [TRIG 4] key to enter OS UPGRADE mode.
  • Open the Transfer application on your computer.
  • On the Transfer CONNECTION page, click “LEGACY OS UPGRADE mode”
  • On the Transfer LEGACY OS UPGRADE mode page browse to, and select, the downloaded OS syx file.
  • Select your MIDI interface.
  • In Transfer, press “UPGRADE”.

A progress bar is visible on device screen when receiving the OS.

When the update is done the unit will restart by itself.

After some upgrades the bootstrap is also upgraded. This upgrade is performed right after the first restart of the device. Do not turn the power off during the upgrade.

Downgrading the device OS is not supported, and is performed at your own risk. User content may be lost.

Should you experience any problems or find any bugs, please report this to

Scrolling to the next sample bank while parameter locking could change the track’s sample.

Navigating back in the Sample browser with [NO] skipped the root screen, causing the browser to close unexpectedly.

Using the quick assign method and navigating folders with [FUNC] + [LEFT]/[RIGHT] caused the Assign sample browser to close unexpectedly at the root.

The SAMPLES menu ([FUNC] + [SAMPLING]) and ASSIGN SAMPLES menu did not remember the last opened directory.

Long sample names clashed with GUI elements.

List of changes from OS 1.01A to 1.02

Improvements

Added a new parameter, NOTE PARAM, in the PERSONALIZE menu where you can select the interaction behavior for whether the NOTE parameter settings should follow the set scale or not. Either turn the knob to set note value in the chromatic scale and push turn the knob to only select values that follow the set scale or the other way around.

On the mixer pages, the name of the page is now shown instead of the track number.

When using the page loop functionality in GRID RECORDING mode, the master playback position is now indicated by a blinking TRIG key on the top row (TRIG 1-8), and the currently played looping page is indicated by a blinking TRIG key on the bottom row (TRIG 9-16).

The LFO destination SAMPLE SLOT could only be modulated if the track used the ONESHOT machine.

Quickly pressing [FUNC] + [TRK] twice changed mute mode instead of exiting mute mode.

When in Euclidean mode, pressing already placed note trigs resulted in trigs remaining on the sequencer when switching to normal sequencer mode.

While transferring samples to the device while in the sample browser, the title bar intermittently flashed the full path of the current directory rather than just showing the current directory name.

Navigating up and down deep folder structures in the sample browser was slow.

The Sample auto-preview toggle’s state was not saved after reboot and always defaulted back to OFF.

The retrig parameters RTRG, VFAD, LEN, and RATE could not be recorded in LIVE RECORDING mode.

Pressing [TRK] + [TRIG] + [NO] gave a reload error message even though the reload worked.

The page looping behavior was not working as intended.
