r02455212, demultiplexer for 7 octave keyboard Roland RD 300SX. Assuming a spares or repair broken piano is not available. Is the IC likely to be obtainable through the barrage of scammers, timewasters and googlead revenue crap, to genuinly purchase one from the far east? As no reference on ebay, I assume all the apparent "sellers" is a big pile of doodoo The die is cracked or failed lead-out wire, on the common for one 8 note bank of keys.
