Improvements: Added the option to route the audio from the Main outputs using Outbox 8. You can now use [FUNC] + [UP/DOWN] to navigate between channels in the channel configuration menus for Outbox 8.
Download the OS file from the Elektron support page. Connect the computer MIDI OUT to the Analog Rytm MkII MIDI IN. Hold [FUNC] while powering on to access the STARTUP menu, then press [TRIG 4] to enter OS UPGRADE mode. Open Elektron Transfer and drag the firmware file in. Calibrate the unit on restart when prompted. Update Overbridge alongside for full compatibility.

Improvements: [MKII] Added Outbox 8 configuration support. Bug fixes: Some devices could become unresponsive when accessing certain samples. A file system check has been added to detect potential problems. If the file system check reports a problem, back up your samples and projects, then reformat the +Drive samples. MIDI messages were sometimes not sent if the device tempo was set to very low BPMs.
Version 1.72 — 30 Jan 2025
Improvements: In the SETTINGS > CONTROLS > SEQUENCER CONFIG menu, there is now a new setting, SAMPLE POS RES, that lets you set if the STA and END parameters should be high or low resolution. The key shortcut to access the PAGE PLAYBACK mode is changed for MKI. It is changed to: In GRID RECORDING mode, press [PAGE] + [NO]. This shortcut is also available on MKII and is added to the previously implemented shortcut of holding down [PAGE] in PLAYBACK mode. Bug fixes: Incorrect tags and machine type could sometimes be displayed when navigating and copying sounds to the Sound Pool. [MKII] It was difficult to see the LED showing the currently playing page when using LED INTENSITY setting LOW. It was not possible to remove a sample lock by pressing DATA ENTRY KNOB D on the SMPL page. When importing projects created in OS prior to 1.70, velocity, aftertouch, performance macro, and scene modulation of TUNE were sometimes not converted correctly. When importing a project that previously was exported from another device, it could under some circumstances, load the wrong samples. Reloading a Sound, Kit, Pattern, or Track could sometimes erroneously also activate the MUTE mode.
Version 1.71 — 16 Oct 2024
Improvements: Randomizing the parameters for the Euclidean sequencer parameter page now bases the randomness range on track length and does not randomize the LEN parameter. The key shortcut to access the PAGE PLAYBACK mode is changed for [MKI]. It is changed to: In GRID RECORDING mode, hold down [PAGE] for two seconds. This shortcut is now also available on [MKII] and is added to the previously implemented shortcut of holding down [PAGE] in PLAYBACK mode. Added support for Overbridge 2.13. Bug fixes: An active GRID RECORDING mode was disabled if the PAD SCALE menu was opened. It was also not possible to enable GRID RECORDING mode again while the PAD SCALE menu was open. The LED BRIGHTNESS screen setting always reverted to MAX after the device was awakened from the screen saver. [MKII] In GRID RECORDING mode, the active [PARAMETER] key’s LED was hard to distinguish from the non-active [PARAMETER] keys LEDs at LOW and MID LED INTENSITY settings. [MKII] When using LED INTENSITY settings LOW and MID and selecting a pattern, the active patterns [TRIG] key’s LEDs, were hard to distinguish from other [TRIG]keys that denote a pattern that contains information. Parameters on the TRIG PARAMETERS page could sometimes end up on the wrong track if they were recorded using LIVE RECORDING. It was not possible to reload a Sound when in MUTE mode. It was not possible to reload a track when in CHROMATIC mode. Reloading an SRC parameter page could result in reloading errors for specific parameters. The HH LAB DECAY parameter did not have INF as max value name. Calibration could, in some circumstances, fail when a previous calibration result was supposed to be used.
Version 1.70 — 22 Nov 2023
Improvements: Added five new machines: SY CHIP, SY RAW, BD ACOUSTIC, SD ACOUSTIC, and HH LAB. Added an Euclidean mode for the sequencer. You can now save a Sound from a specific trig on the sequencer, complete with its sound- and parameter locks applied. Added the possibility to set a specific number of sequencer steps as record length in the sampler, resulting in loops with the exact length. Added pad scales and fold functionality for when playing the PADS in CHROMATIC mode. Implemented functionality that makes it possible to loop selected pattern pages. Added the square waveform as a parameter value for the WAV parameter in the BD SHARP machine. The BT CLASSIC machine now has a new PITCH ENVELOPE parameter. Added two new PULSE WIDTH parameters for the CB CLASSIC and CB METALLIC machines. Added slew functionality to the RND waveform for the LFOs. When RND is selected for the WAV parameter, the SPH parameter now sets the amount of slew. [MKII] Added an LED brightness setting parameter in GLOBAL SETTINGS > SYSTEM. It is now possible to see which PARAMETER PAGES contain parameters with parameter locks. When pressing and holding specific trig in STEP RECORDING mode, the [PARAMETER] keys that contain parameters with locks light up. Improved oscillator tuning by adding new calibration functionality. Implemented the possibility of generating a random name from the naming screen when naming a Sound or a pattern. The NOTE parameter on the TRIG page now shows the note value and the number of semitones in the screen UI. Improved the naming of the DUAL VCO, IMPULSE, and NOISE GEN machines by adding machine type group naming. The new names are SY DUAL VCO, UT IMPULSE, and UT NOISE. [...]
Version 1.61E — 1 Feb 2022
Version 1.61B — 2 Jun 2021
Samples could sometimes become corrupted when transferring them to the Elektron device from an M1 Mac using Transfer.
Version 1.61 — 7 Apr 2021
Improvements: Added Overbridge support for macOS Big Sur. Improved the response of the TRACK LEVEL encoder. Bug fixes: Stopping the sequencer did not send a note off message over MIDI on channels that were set to send MIDI notes. Some unused factory content patterns were not properly cleaned and empty. The error message “Missing Cal:Pads” could sometimes be erroneously displayed even though the calibration was not lost. SysEx dumps could become corrupted when sent to certain computer software.
