It seems there is no way to update the boot code at the moment. Since I've tried to downgrade the software the synth is not able to receive Midi anymore. Setup is still the same, was working before and not working now.
You think is necessary for me to upgrade the boot ROM on the Hawk 800 or would be the code enough?
I'm new to this and I've recently got my first Poly800 so any help is really appreciated.
Thank you in advance
