is the sustain pedal solenoid or heavy iron trapwork near the E5 key physically or the circuit that reads the hammer sensors? is it possible there is something strange about the hammer sensor for that note or maybe the trapwork some how got adjusted so it is effecting the hammer sensor or the electronics connected to it? could something in the damper tray or stuck on it like a dropped mute or ??? i have no idea how close the damper tray damper wires etc are to the key sensor or if it is possible for something to be moved by the damper mechanism that could be effecting the hammer sensor. be getting into the optical sensor path for the E5 note?
the hammer sensors should be pretty immune to ambient light but is there a bright light shining on the piano that might be reflected into the hammer sensor when the dampers are actuated? does the problem occur if you have all lights off. i once had a strange problem of an optical counter not working properly when the device it was on was used in bright sunlight.
Hi Bill,
Here are two midi files. The first is me playing nothing but sustain pedal three times. The second file I put the sustain pedal down and then play E fours times about one second apart...
Its quite the conundrum... I have been looking for other causes but have come up with nothing.
Maybe my set up will give you a clue..? I have both a DSR1 and a DKC100R connected . The cable goes from the piano into the DKC100R and then from there to the DSR1 via midi cable then from there to my laptop. Could one be interfering with the other?
Cheers,
Carl
