i own a great disklavier mx100a since many years and i just discovered this great forum.
Some questions...
1) Has anyone experienced any problem connecting both midi in and out with computer ? It seems that my disklavier works properly only if i connect just midi in or midi out...when both are connected to midi interface, some strange messages and not all notes are played correctly. When i disconnect one of the midi connector from the interface, the behaviour is ok. Is it normal? Is my mx100a "broken" or too old? Any firmware update i may request? I know it's not flash - upgradable...it needs eprom replacement or reprogramming, but it's not a problem for me.
2) Is it possible that the only way of using midi connectors is putting an empty floppy inside the floppy disk drive? No other way to work with midi connectors?
3) Is it possible to use a module for disklavier markIII (also rewiring it if the cabling is not the same) ? I may take one from a friend that upgraded his markIII to dkc-850... i know it may require some extra wiring and cabling but if anyone made it, i would appreciate if he could help me doing that...thanks.
4) Is there any way to "mod" an mx100a to improve midi capabilities and is there any "mod" for eprom firmware modifications that anyone did ? (for example avoiding putting a floppy inside or others)
Thanks!
