In the end, I bought an expander EMT 10 connected to the Midi and the Clavinova's audio input.Leave a comment:

With reverb OFF just lit makes some very strong shocks when playing, then the sound disappears. While with the ON reverb there is the non-distorted sound but very low, the signal is very low as a 1 watt amplifier.
Does anyone know if it depends on 3 rom memories?Leave a comment:

Re: Yamaha Electric Piano CLP550 no keyboard output
Hello everyone I too have a clp 550 defective with distorsion.
I measured the signal bus going IC12 , the four input signals are ok (SYW, 0G, S00, S01) but does not come out the serial signal on pin 27. I tried it to cool and heat this integrated and in fact made some noise and then remains mute. I do not know if the INPUT serial signal is correct (ROM?). Someone can make measurements on ic 12 on a piano that works?
Thank you
