I bought used M-AUDIO Keystation 49e. I couldn't check it, and later I found that a range from E2 to F3 doesn't operate. I opened the keyboard and found that something had been spilled on it. I cleaned it up but the problem persists. I believe that the block EK49.04.A04 (or a chip on it) is damaged. My question is: can I order a replacement for this part and where? Thanks.

No, but you might try loading parallels and then running the older XOS on that.... its worked for me with other applications

This should help any further assistance please feel free to contact me.

It sounds like a hardware issue, you will need to get your keyboard repaired

Thanks

who cares its just a millisecond and its just takes a while for it to load on the computer nobody actually counts the time it takes

you should go to your  utilities --> audio midi setup and make sure your system is recognising your midi device. Play around with your midi settings, see if you can get something going.
Otherwise the problem maybe with the software clashing with Leopard. Double check on the manufactures website that their software is compatible with 10.5.6, or they may have an update for you.
Thirdly you could check if you keyboard is working correctly by opening garage band and making a new software instrument track, press record and see if you get any thing.
Good Luck hope this helps.

I just found this in the M-Audio forums. I've just called the number and left a message at M-Audio requesting a callback. I'm really hoping that tech support will have a solution for whatever is causing this malfuntion. . . I'll post here again when the parts come.

Sounds like it might be a power supply issue. Unless it is mains powered.

Try removing all other USB devised. If that doesn't work its worth try a Mains Powered USB hub.

Buy a Mac, Then you won't have that problem.

Youve gone through the settings to make sure it is sending and your computer is receiving on the same midi channel?
