Hey, Bohan…  Thanks for your precious suggestion…

Unfortunately, Direct Updater does not appear to be able to communicate with the H9, even over a direct USB cable…

Guess I should open a ticket?!?  (do consider I live in Italy)…

If and factory reset doesn't work and your PC/Mac cannot recognize your H9 as a USB or MIDI device, you should probably get it repaired. Please contact the seller or email support@eventide.com
