Hallo All!!
I'm broke my mind over my MTX9..
This sh*t don't give any sounds to me...
I replaced a battery recently... but this takes no effect..
Inside machine is clean and has no leakage...
Someone have schemes or service manual of this "computer"?
And after power up it blink all leds in sequence!
Triggers no responding...
I know this one sucks but i found its sounds awesome (some eeproms
fits in my Oberheim DX:))

Any help will be great cause i didn't find much info om MTX9 here..

Hallo again!
Recently i am resurrected my MTX9 and after years of craziness it
became normal fore some hours, ha ha!
Its power up some times work correctly, other times not... 
Everything works and sounds but this machine remains very unstable...
Many bugs in system... Sometimes user presets make him mad, but it
remember all setup and kits i made (incl. MIDI).. Strange but this
thing have 13 sounds instead of 11... (Extreme Gate Tom and Simmons
Snare as bonus?).. And how i can check voltage of main power supply
maybe problem still there?
Thanks!
