Normally Strings voices has noise in the
higher keys ( C5-C6).
This is unfortunately normal and nothing strange.

Thanks for your answer.

I hope so , its normal , its really like a train in the background riding , when you detach the touch knob , its gone
butt you only here it if you softley touch the key.

I try it in the store to another psr , and its the same , maybe a bad sampling of it.

Maybe someone to help with the good Master EQ settings to use , yours are the experts who have a longer use of it.

i am a newby to my Psr 975.

Many thanks in advance four your help.

Best Regard.
