Initially, upon flashing the latest HxC firmware, I would have a successful read on the first file, but would usually get a "FORT" error appearing on the Electone MDR Panel (which is saying that the disk is not formatted or corrupted) when I read the 2nd or 3rd file.
Jeff worked patiently over two days and finally narrowed down to some strange "index signal timing" that this Electone required.
Thank you Jeff. Seldom would one get such great support. ❤ ♬
