I have a problem with my GW-7, it's about keyboard velocity. On the EXR-7 I found that it is able to adjust keyboard velocity from low to high, but on the GW-7 there isn't that feature.
The playing is terrible, because the keyboard is very sensitive. Maybe it is able to upgrade the firmware of the synthesizer? I have no idea what to do...

Do you have any suggestions? Thanks a lot.
