Dear nice people at IK Multimedia I recently updated the firmware of my Uno Synth Pro to the latest version 2.02 and in my surprise it deleted about 4 months of preset design on my side.
You can imagine my frustration but what is done is done (and I am pretty sure it is impossible to get my presets back) though a warning that the firmware update will wipe out user generated presets would be nice on your end.
