Help on M.Volume voice setting

[Practical Senses]

Hi!
I want to adjust the volume of voices (to equal the volume differences), so I'm selecting voice (for example 002 Bright Piano), press Function button, select M.Volume and input, for example 127 (initial parameter is 104).
But when I select another voice or turn off/on keyboard this settings revert automatically to 104 (initial factory setting)
Is it possible to store M.Volume settings for each voice or it's possible to do only with Regist Memory?
P.S. TouchResponse and other settings stores normally
Thank you.

No it's not possible to keep the M... settings, you have to store your changes into a registration memory.
