Thank you! But there is no rush on my behalf.
Mostly, I'd like to know which of the 3 following statements apply to my situation:
1- The U220 is too complicated to work with for what it's worth (hence the few people still using it)
2- My unit has something broken inside or a corrupted program
3- I'm too stupid to make it work
Meanwhile, I still have some Sysex Device ID
to try on...
