Here is the re-init procedure

1. hold function+reset and power on 2. "test mode y/n" press yes 3. rom version -- press function 4. "route test" press function 5. it says "fail" that's ok, press function 6. "destructive test" press yes 7. "ram test/ram good" press function

After which you should see an elapsed timer. Turn it off for a few seconds and turn it back on. Unit should be at "#1 INIT".

Keep in mind these things use an old Z80 processor, the same CPU found in old Radio Shack TRS-80 computers. They are very sensitive to static electricity. If the reset procedure in the above doesn't work for you, then your processor is most likely shot. In which case, you will have a hard time finding a new one unless an electronics surplus dealer has a stockpile of Z80's laying around.

In this day and age, you can get more mileage out of multiple USB MIDI interfaces and have a PC control the routing with MIDI-OX for Windows or JACK for Linux. So if your MX-8 is dead, don't lose too much sleep over it, they're not hard to replace with USB MIDI interfaces, and give you far more capabilities at the same time.

I bought my MX-8 back in 1993 and it worked great for the longest time. Then all of a sudden, the LCD would just light up and nothing would be displayed on it. Sent it in to Digital Music Corp (or, now I guess they're called Voodoo Labs, www.voodoolabs.com) and they just did a factory reset on it. Sucks because the manual doesn't tell you how to do a factory reset. A year later, the same thing happened and I had to call them to find out how to reset it myself. Today, I have the same problem with the LCD, but the factory reset won't fix it. So I guess I have a $400 boat anchor in my rack. If anybody has any suggestions at all for a new MIDI patch bay, I'm open to anything. Seems strange that MIDI patch bays are relatively extinct now. I can't imagine working without one these days. Maybe I should design my own and go into business for myself again. :-)

My MX-8 seems to be an earlier version with a built-in power supply and the front panel does not have that blue stripe going across it. It seems very solidly built so perhaps the later version was a bit shoddier in construction. Anyway I find this unit indespensible for my live and studio setups. Since I use more than one controller keyboard, it's great to be able to re-route your entire studio system at the press of a button, so your master becomes your slave and vice versa. Also the patch chain function is great in that you can send patch changes to all your keyboards & modules. Another useful feature I use often is MIDI offset so that if your controller is set to channel 1, you can control a module at channel 3 by 'offsetting' by 2, instead of having to change either the master or slave MIDI channels. Plenty of other advanced features too numerous to go into here. The contacts on my buttons could probably use some cleaning as they sometimes double-register, especially the function key, which drives me nuts sometimes. I've had it for 10 years not and couldn't imagine getting by without it now.

I like this baby a lot. My current setup is a Oberheim Cosmos Stagepiano, a Korg Z1 VA and a Roland JV-2080 Module. I Needed the MX8 to merge the signals of my two controllers so that both could work the JV-2080. But on top of that it had some, in my opinion, nice processors. My piano is without any assignable knobs and buttons, but now i just merge the signal of the Cosmos and the Z1 together, but filter note on/off and program changes from the Z1 away. This leaves me with the option to play both controllers and using the knobs on the Z1 to edit the JV-2080 live, without the Z1 playing along on the module. For a larger setup and for live use, this unit is really nice.

Mine works without a problem. But that does not mean it is the best. My wishes: If only it had merged 4 channels. My complaints: Cheesy keys , dark LCD, very limited processor capability, relatively poor construction... It is just OK if you get one for cheap.
