MPX1Z (U1 Mark II XG with silent system) - no sound from silent piano

MPX1Z (U1 Mark II XG with silent system) - no sound from silent piano

2019-08-22 by James Fry

Hi all,

I have an MPX1Z Mark II XG U1 disklavier that I purchased new in 2001. Recently I went to use the silent piano for the first time in a few months and there was no output. If I adjust the settings to play the XG sounds I can hear them fine. MIDI output from the keys appears to be working, and I can play / record and the keys all move etc.

Is there something obvious I might be overlooking? If not, what is the prognosis? Is it likely that a repair is going to be cost effective on such an old (and essentially worthless) instrument now?

Many thanks!

James

Good morning, everyone.

James, does your control unit have a “Voice” button? If so, when you push it, is there an option to set “PianoTone” of On or Off? You might check that.

Hi George,

Thanks for the quick response - it does have the button and the 'piano tone' is set to on.

If I adjust the voice from '###' to a number (eg 001 for GrandPno then I hear the XG voice, so some of the audio path is working at least). The XG sounds come from a DB51XG card (presumably a variation on the DB50XG soundblaster expansion) so sound is getting from there through to the headphone sockets at least.

Do you know where the main piano sound comes from? Is there another board like the DB51XG or is it built into one of the main boards? If I turn the volume control all the way up I can hear a very very faint chromatic sound in the background noise, but it's barely audible.

Many thanks again,

James

The main piano sound comes from MIN Board
I recommend to check following points.

1:Aux in and aux out sound check.
2:Enter test mode and check piano type ( UPS)
3:Enter test mode and do the MN test.

Good morning, everyone.

James, there are 2 other things that I can think of: Local Control and Reset.

If your control box has a Local Control option, make sure that it is on. If you can find a Reset option, I recommend doing a reset of the settings.
