keys not working properly
I have a yamaha piagerro npv60. The B & C keys have problems with it. Here's the scenario: - both keys played together, respond to velocity. If you play fast trills or scale, if u hit one first, the next key, either B or C wont sound. You have to time it properly to work. If you hold down either B or C and then press the other... The latter won't sound. But take note, in combination with other notes all is fine. Same issue for the F and F#. This happens in all the B&C and F&F# on the keyboard. Please help! Thanks in advance!
