@Balrong It is possible to install a click by browsing the web site open-store.io, download it and install from there. yes the install is an option as advised by @mrt10001. I have found no other way to install again with UT already installed than running 'sudo reboot bootloader' and launching the installer from there (after connecting the USB cable of course).

@Balrong : You're welcome! It's good to hear that you managed to restore your notes. Kind regards, Alter

@mrt10001 Fair enough. Worth a try though! Thanks

Another update: Qtractor can be installed via Libertine (with libqtcore4 as prerequisite) and functions. Trouble is that Jack doesn't work and so actually recording on Qtractor hasn't happened for me yet. I think a real-time plugin is needed. I'm hoping someone who knows more than me will weigh in, but would this be useful to us?: https://ubuntu.com/engage/an-introduction-to-real-time-linux-part-i Or does anyone know how to get Jack working with interface? I will mess around with ALSA and see if I can get some MIDI stuff done. Balrong
