Question about Digi-Tech Digitech Vocalist Live 4 Harmonizer
I have an rp2000, everytime i power up a message appears ''mdsper'' and it does not function ,i have tried to reset to factory presets but does not work ,is the solution to pay for repair
If you have ever tried to research this error message and found that there is no real answer to this, it is because "mdsper" is a general error message that can be the result of a few things. It seems to be a senseless thing to do until you realize that if you were Digitech, this would be a boon to your service department when these things go out of warranty.
Most commonly, it can show up if the internal battery needs to be replaced. As you know there is an internal battery in order to store patches in memory. Well, these things tend have (in my experience) a life of between 3-8 years, but can last longer if the pedal isn't used much.
It could also be that a power surge could have knocked out the memory in the main chip, rendering the pedal completely useless.
Another common situation is that many people use a non-factory power supply (wall wart) and often it may have the correct voltage, but not the correct MaH. This mismatch can blow out the unit if too high, or cause the unit to malfunction, if too low.
You should also know that some people continue to do the factory reset procedure until it "takes". So sometimes continuing to try the reset procedure could lead to success. You may wish to try and reset it quite a few more times (maybe 20?), then, if you have the correct power supply and are sure that is not the problem, you may wish to switch the internal battery yourself. Apparently it is an easy replacement. The one thing i do not know is the battery information and where to obtain it aside from going directly to Digitech. I am confident you could find it cheaper through another source. Good luck. Hope this helps.

You can restore the settings in the ME-25 (memories, tuner
reference pitch, and knob response method) to the values set when
the unit was shipped from the factory.
Performing a factory reset causes all settings saved in memory to be
lost. If you want to keep the memory settings, use the ME-25 Librarian
(p. 11) to save them on a computer.
Hold down [EXIT] and press the MEMORY DOWN
pedal at the same time.
"FA" appears in the display.
The Tuning Guide flashes.
Press [WRITE] again.
The display flashes and the factory reset is executed.
Never turn off the power while factory reset is in progress.
