Release v22.4 fixes a storage issue which caused errors when storing large patches, contains important refactoring and robustness improvements, and brings support for the Genius Eurorack module.

Known Issues: USB Host does not support reconnecting devices

To ensure a smooth upgrade, consider to do ERASE STORAGE from the Device Page first.

To upgrade a device with MIDI boot loader go to the firmware page (Chrome/Chromium or Edge browser). To upgrade a legacy device with DFU bootloader go to the webdfu page (Chrome/Chromium browser only).

Download a .syx file for use with the MIDI bootloader, or .bin for DFU bootloader.

Please make sure you use the correct file for your device and bootloader!
