Korg 01W - Global settings - Midi Transpose frozen

[Derosa34]

Hello,

I am wondering if somebody could explain me why I can't change the midi chanel out or the Key Transpose few minutes after powering the device on.

Use Case:
1) Switch the 01W on
2) Go to Global settings
3) Change the midi channel out from 01 to 02 (press value up button)
4) play some notes
5) try to change midi channel out from 02 to 01 (press value down button)
6) nothing happen... cnahhel stay at 02

Same if I want to change the key transpose

At the end, it seems that some global settings can't be changed after a moment... I really don't understand why.

I probably miss something.....

If you could help.

Thank you

Christophe
