1) I have the user's manual and the service manual in pdf format.
2) No, because I don't know how to do it. I couldn't find any instructions anywhere.
3) Ummm... do you mean the readout of the lcd display or the readout of the midi software? After pressing the Function button, there is a text "FUNCTION CONTROL | MASTER TUNE ADJ" in the lcd. The software doesn't react at all.
4) No modification or damage can be seen.
