Hi Zhao,
I’m glad that I found this forum yesterday.
I bought a CME product (CME-UF80 Classic) 4 weeks ago and unfortunately It has a similar problem.
I try to use this midi keyboard with my Roland Sound Module (Roland XV-2020) and when I change the program to (for example) 3 on the keyboard, the Module changes the program to 6 (and 8 instead of 4, and 10 instead of 5, and 14 instead of 6, and so on…)
I had a red CME-UF8 keyboard before that and it was working well with this module.
I attached a picture about the midi signals.
The actual firmware version is UF8 2.01 and I tried to reset the keyboard.
Please help me!
Thanks
Zsolti
